Product Description

Includes HAYAUCHI 21-ft 3-Extension Extra Large Tooth Telescoping Pole Saw – 179-39, Blade Cover

From the Manufacturer

The Silky 179-39 Telescoping Landscaping Pole Saw HAYAUCHI 390 (21 feet) is a bestselling, professional, aluminum telescoping pole saw – the pole saw of choice by professionals. The aluminum alloy extension poles are oval shaped, providing precise control over the direction of the blade (especially important for high cutting) and giving strength and rigidity to the pole thus reducing bending to the minimum. The base pole has a pole-end shock absorber and comfortable rubberized over grip which ensures good hold and control. The 15-2/5-inch curved blade utilizes proprietary Silky 4-RETSUME (Four Rows of Teeth) Technology. Teeth are set in such a way that there appears to be 4 rows of them. Ideal for toughest pruning jobs! Blade can be adjusted to two different angles for lower or higher cutting and features an upper and lower sickle. The upper sickle is used to cut vines and lower sickle to undercut bark. Lower sickle provides clean cut without damaging tree, while upper sickle prevents blade from slipping off limb. HAYAUCHI is the finest telescoping pole saw available on the market today. Black rigid-plastic blade cover is included. Made in Japan. To allow effective use of HAYAUCHI pole saws, two locking systems are incorporated to assure structural rigidity of the extended poles: 1) locking pins/buttons – the primary pole locking mechanism; and 2) friction clamps – the secondary pole locking mechanism. The two systems are designed to work together. This dual locking system allows 100% of the effort at the handle to be effectively transferred to the blade up to 21 feet away. Spring-loaded locking buttons allow multiple length adjustments and safety friction clamps hold the extensions firmly in place. Safety considerations require that the pole saw user must wear a hard hat and eye protection at all times. Manufacturer Warning: Do not use aluminum telescoping pole saws around electrical power lines or equipment. Electrical shock may result. Incorrect use of the Silky pole saw may cause injury.

Customer Reviews

Silky Pole Saw ~ reviewed by Informed Buyer

I spent significant time researching extension pole saws that I could use to prune the many hard and softwood trees on my property without incurring the expense of a professional tree company. I was impressed by the 21′ Silky Hayauchi but very skeptical about its ability to cut branches at this distance off the ground. I was also skeptical of my ability at age 66 to physically handle this saw at such an extreme height. I called the Silky Store and spoke to a representative regarding my concerns. They advised that I would not experience any problems as long as I engaged the double locking system on each pole extension and allowed the saw to do the work. They explained that the blade was designed to cut only on the pull stroke and that gravity would provide most of the required cutting force. The effort required on the push stroke would be minimal since no cutting occurs on the up stroke. Based on their advice and the Silky guaranty I purchased the 21′ Hayauchi pole saw. I received it in 2 days! I was totally amazed with the incredible performance of this very high quality saw. I easily cut large limbs at least 20′ or more off the ground. The guideance received from the Silky Store representative combined with my actual experience with this superior quality tool was very impressive. I intend to purchase additional Silky saws from the Silky Store.

Best Tool I’ve Ever Purchased- Great Design-Quality-Delivery ~ reviewed by Hoosier

As engineers tend to do, I reviewed the specs of several saws designed for cutting limbs before I purchased the unit.

As evidenced on this site, the ratings were all very high except for cajun-dancer’s. When I went to his other reviews, I noticed that almost all of his reviews are very negative regardless of the product or manufacturer. His comment regarding the pole coming apart warrants a comment. The telescoping sections have popup pins to lock sections in place when properly used… key words being “properly used.” As is commonly the case, the person who doesn’t use the product properly blames his problems on the product. Just imagine him building his own saw by putting a blade on the end of a pole.

Because of the other reviews, I ordered the Silky Telescoping Landscaping Pole Saw HAYAUCHI 390 21-Feet #179-39 to remove tree limbs damaged by high winds associated with Ike. I choose to use Amazon’s FREE Super Saver Shipping and received it 2 days later.

The only assembly required is installing the cutting head using the (2) bolts provided.

I used it to cut approx. 75 limbs that were 1/2″ to 5″ diameter. Having cut many limbs without the device in the past, I was very pleasantly surprised as to how much easier it was to cut the limbs that were 8-20+ above the ground.

I have concluded it is one of the best tools that I have ever purchased.

If you decide to purchase the unit, I suggest:

*Start with cutting small limbs that are lower to learn the best techniques and remind yourself of safety considerations: i.e. not being where the falling limb can strike you..
*Determine the length of pole needed for your highest limb. (A significant number of limbs that I cut could not have been cut with a shorter unit.)
*Not loaning the unit to anyone who has a history of reckless behavior and/or not using tools properly….

Best tool I have ever owned ~ reviewed by Greg

Got my Hayauchi about 4 weeks ago, and have been using it to limb trees just about daily ever since. The 21-ft extension, coupled with the stability of the oval-shaped poles, allowed me to get far up the tree and with very little of the wobble that I’ve experienced with other, much shorter, pole saws at full extension. The system for securing the poles when extended is top notch, featuring spring-activated “buttons” that pop up through a hole in the shaft and clamping tabs that also secure the poles in position.

One caveat: the saw blade (great blade by the way) is secured to the pole by a sleeve with two through-bolts. These in turn are secured by wing nuts. Be sure to check the wing nuts for tightness after each day’s use (and maybe midway through a heavy session. I’ve already lost the lower bolt/wingnut twice due to failure to check this.

Way overpriced, way hyped—- ~ reviewed by Austin reader

First off, I’m a Certified Arborist, ISA. I own two retired Hayauchi saws. I used them, daily. If you are a homeowner in need of a reliable saw that you can baby and take great care of as you use it and store it, this saw may be the one for you. Then again, why would you need to spend such big bucks for a saw you will only use a few times a year? There are pole saws out there for less than half the price and they will do you just fine. For professional use, this saw is a joke, plain and simple. If you look at it wrong, it will bend, making it impossible to fully retract. In no time at all, the webbing on the handle begins to unwind. The end cap disappears, as well, just as the webbing stabilizer band, midway up the lowest section, lets loose. Yeah, great quality, right? The blades are nothing to write home about. They cut OK, but just OK. For about a third of the price, you can order blades, drill holes to match, and use them. I only bought the second saw because I chalked up the poor performance of the first to a fluke. Nope, both are mostly junk. I gave this saw two stars because for the first two weeks, or so, they are fun to use, and do a very good job. Thing is, with regular use, they bend, start falling apart and become a real pain, literally, to use. The sections do not smoothly telescope, after about those first two weeks, if you’re a production worker. Pull one totally out—Oh yeah, real fun putting it back together. The “Hang Fox” is a hoot. It is a hook-like piece you screw onto the blade housing. It is made to fit only this model, as I recall. It made me laugh when I received it in the mail after shelling out, I think, about $30, delivered. It’s made of chromed plastic over tin. Yeah, I really liked trusting my skin to that piece of garbage–NOT! Silky is overpriced on all of their stuff, no lie. They know that there is a “snob factor,” in owning their garbage, and they now are capitalizing on gullible arborists and homeowners. Want a far, far better alternative? Order two, six-foot, Jameson fiberglass pole sections that snap together. Order one eight-foot section. Order a Jameson blade head that has an integral hook. Order a few blades. You will spend less money for this equipment, about $150, and it will last a lifetime, remaining mostly trouble-free. FWIW, when it comes to fiberglass sectionals, that I just described, you can buy the same/similar equipment made by different manufacturers. It’s all good, for the most part. There is a reason why this fiberglass sectional equipment is still found in the kits of 99% of all working arborists, out there: You can’t improve on hard-working equipment that lasts. Silky is a con. Don’t get taken! UPDATE: 4/6/14: I was cleaning out my warehouse and found my two old Hayauchis. I decided, on a whim, to cut out their bent sections and restore these saws with new bat tape, improvised end caps, etc. OK, that I did. They were looking good and telescoping fine. Then I took them to the yard to try them out. Whoa! These guys are heavy and awkward to use! I had forgotten how heavy they were compared to my fiberglass sectionals. Also, even with light sawing, I could see how the 21′ unit, now about 18′, was flexing and threatening to get yet another bend. I couldn’t believe that I ever used these units on the job. Again, I do not recommend these saws, and I can add that their weight is another negative factor. Also, while I have not researched, in depth, the many electrocutions that happen to workers in my profession when their pole saws contact power lines, I can bet that most of the saws they were holding were, most likely, metal ones, like these. While dirty fiberglass, including foam cores, will also conduct electricity, I would much rather take my chances with them versus the Hayauchi.

An Excellent Saw ~ reviewed by Stephen Parker

I have my own business in Lawn maintanace and often trim palm trees. I have been using a chain saw that extends to 11′. The Trees that I trim have now grown beyond the safe length of use on the pole saw so I decided to purchase the HAYAUCHI 390 21-Feet saw. I used it for the first time this week and it made light work out of taking down palm leaves. Plus I could get the saw into spots where I couldn’t get the chain saw. It’s light weight and sharp, well worth the money.

Switched to sectional fiberglass pole – much better ~ reviewed by Engineer

I posted a 5-star review when I first bought the 21-foot Silky in December, 2010.

Realized that I wasn’t using the Silky, so I recently bought a set of lightweight Jameson blue sectional fiberglass poles. Much better.

After using the traditional saw, I thought to find my review of the Silky.

I was surprised to see the date on that review and realized that I had stopped using the Silky quite some time ago because it was such a hassle to set up and frustrating to use.

Even when brand new and perfectly straight, it is a wrestling match to get the Silky extended, which you have to do on the ground. It takes a lot of thumb pressure on the relatively small locking pins to keep a pin pushed in while sliding the tube section out. Easy to pinch your thumb. By contrast, as another reviewer points out it is easy to extend a traditional pole by sliding it up the tree and snapping on the sections.

The Silky flexes quite a bit at the joints between the telescoping sections. The traditional fiberglass pole flexes – but like a single pole due to how the tapered ferrules fit into each other.

Haven’t bent my Silky yet but it is clear that I would have bent it sooner or later if I continued to use it on big limbs that might fall on the pole.

You can’t use the Silky anywhere near the power wire going to your house because the pole is all metal. (Of course you should always be very, very careful even with a insulated fiberglass pole saw.)

One big motivation in my buying the Silky was that it is compact to store. However the six-foot fiberglass sectional poles are also compact to store.

In summary, the Silky is a very clever product and no doubt the best telescoping pole saw available – but the traditional sectional poles are much easier to set up and use. And I feel much more confident using the traditional pole saw.


* Based on the comment here that the two wingnuts holding the blade in place tend to come loose, I replaced them with metric nylon locknuts (size M6) from a local hardware store. (I just sheathed the blade for storage, so the nuts being easy to remove didn’t matter to me.)

* Easy to pull the last telescoping section out of the base section, because there is no mark on the telescoping section. I drew a line all around on the aluminum tubing with a permanent marker.

* If you need to get one of the telescoping sections back in, hold the Silky so that the locking pins face downward. There is a loose part in each latch that blocks reinsertion of a section if the locking pin is upward.

The “21-foot” designation is nominal. The actual distance from the end of the base to the base of the cutting edge is more like 19 feet. The official US website gives the length as “20.7 ft” – which must be the distance from the end of the base to the tip of the blade.

QUALITY PRODUCT ~ reviewed by Gerry Ecker

This is not your Home Improvement $30.00 pole saw. This is a very well engineered and built product. The telescoping Aluminum shaft is well engineered and easy to extend and will not slip like the flimsy fiberglass poles with compression sleeves.
I use mine for trimming Queen Palms. The key with this saw or, any other saw for that matter is to let the saw do the work. Don’t try to force it or put excessive down pressure on it while cutting and you should not experience any problems. The blade is very well designed and is of a gauge that resists the twisting and distortion of the cheaper blades. It is also quite sharp and should be handled with care. One of the reviewers said that he was “66 and had no problem using the saw.” I am 72 and I don’t have a problem using it either. It is a bit pricey but you do get what you pay for.Silky 179-39 Telescoping Landscaping Pole Saw HAYAUCHI 390 21-Feet

nice saw ~ reviewed by dm

For the reach, this is the saw to get. Fiberglas and aluminum round pole long reach saws from other manufacturers aren’t designed as well, and generally cost the same or more anyway (pro interlocking section saws, not those extendable things like from the hardware store). The Silky saw is certainly more versatile too. It’s quick and easy to go from an 8′ pole saw to 21′, and a few lengths in between. It’s well made, and works well too. I get the feeling that the people who make Silky’s saws have actually cut trees with them. Other saw manufacturers don’t seem to use their own products.

Silky’s blades are well made. Note that the replacement blade for this saw is about a third the cost of the full saw system. That said, I think it’s a good investment, and in the end will probably end up costing less than the alternatives anyway. Silky has repair/replacement parts for every part of every saw they make too.

For heavier use, it might be worth getting the Hayate (similar, but heavier duty extension tubes). It flexes less, but weighs more. Really, the Hayauchi is probably the preferred pole anyway. It’s reasonably light weight, and reasonably stiff.

I think I’d get one of these before a pole chain saw. A good pole chain saw has its place too, though it’s got limited reach, compared to the Silky (and certainly costs more). Keep in mind that a pole saw is only intended for branches a few inches in diameter. Much bigger than say 6″-8″ in diameter (and that’s pushing it), would be better cut by climbing into the tree, a ladder, cherry picker, etc.. For safety’s sake. (because some other reviews mentioned limbs that weigh several hundred pounds getting cut-and they do fall down as part of the cutting process…). Part of that length helps get you out of the way of the falling branches. What do you suppose the cost of a trip to the hospital is compared to doing the tree cutting right is? Does that end up being a savings in the end?

My gosh, what a fantastic saw! ~ reviewed by Comdet

Up until recently, I was using a pole saw/lopper combo that I bought from a big box retailer. Thought that all pole saws were pretty much the same. Boy, was I wrong!

I purchased the 21 foot version of this, and have been absolutely amazed at how well it works. First and foremost, the saw itself is incredible. Cuts through limbs like butter. It has a blade so you can score the bark to prevent tearing, and is built to minimize (actually, pretty much eliminate) having the saw get bound into the cut.. I’ve gone through 6+ inch branches without any problem. Just let the saw do the work, and remember that it is only cutting on the downstroke.

The pole itself is also a pleasure to use. Very lightweight, but still sturdy. It has a double locking method (a button that clicks into a hole, plus the customary friction snaps) that completely prevents the pole collapsing regardless of how rigorous you’re sawing. Note, however, that it is not infinitely adjustable — to use both methods to secure the pole, you have to fully extend each segment. Now, you can use just the friction snaps and they will hold the pole, but not as securely as using both methods.

There’s another model (Hyate) that is even more advanced, with a more rigid pole and even better saw. I went with the Hayauchi for three reasons: cost, lighter weight, and (most important) the fact that you can purchase a lopper head attachment. The latter is not made by Silky, but, from what I’ve read so far, is of comparable quality. It only fits on the Hayauchi, so if you want to switch out the blade for a lopper, this is your only option. I have not yet purchased the lopper head, but will update this review once I have it and have used it a bit.

There’s also two options for a hook. Get the hook that only works with the Hayauchi, NOT the Hook Fox. The Hayauchi-only hook attaches more securely to the pole than the Hook Fox (plus is about half the cost).

If you’re looking to do some trimming without using a ladder, this tool is a must have. For me, it’s paid for itself many times over already since it eliminated the need to hire a tree guy to prune the higher limbs. Plus, just like in Kill Bill, you can be armed with some fantastic Japanese steel!

Reaching New Heights ~ reviewed by P. Hussey

This telescoping pole saw allows you to safely reach and trim branches 25′ in the air. Both the pole and saw are made of the highest quality materials. The pole is oval in shape which provides strength and minimizes the flexing that might be experienced with a round pole or a pole of thinner construction. The pole can quickly be adjusted to any height up to the full 21′. The saw itself is massive when compared to any other pole saw I’ve ever seen or used. It has an unusual double tooth pattern that minimizes the chance for the saw blade getting caught up while cutting. I was able to cut branches 3″ in diameter with just a few strokes. If you need to cut branches high up in trees while remaining safely on the ground, I highly recommend this product.Buy it at Amazon
