切れ味が良くて楽だった。

めっちゃ切れます。少し遠い枝も届いて切れるので重宝してます。ただ太い木を伐採するのはチェーンソーには負けます。切断面も綺麗に切れます。

年金生活になり植木の剪定に毎年10万も払うのが大変になってきたので、背の高い木を切るために購入しました。 68歳、女の私でも、太めの木を切ることができて嬉しいです。

こんなに切れるノコギリ初めて見ました。直径30cm位の丸太も、楽々切れます。 背中に背負えるケースも便利です。 これはいい買い物をしました。

イチョウの少し大きな木を伐採しました。 斧と併用です。 そんなに疲れもせず切り倒しました。 玉切りも楽でした。

ノコギリ関係はほとんどシルキーです。今まで他のものも使っていましたが、Big boy 以降は全てシルキー。信頼度が違います。

びっくりする位デカイですね。太枝はあっさり切れます。小枝はかえって小さめのシルキーボーイの方が取り回しいいです。替え刃も高いですが、切れ味に見合います。

Prova di taglio rispetto l'archetto da muratore questa taglia di piu, i denti sono piuttosto grandi e tende a impuntarsi percio la giusta tecnica è quella di non spingere quasi niente e sfruttare tutta la lunghezza della sega, si fatica anche con questa ma vuoi mettere la soddisfazione? Lo strumento dal punto di vista costruttivo è impeccabile ottima anche la custodia.

This purchase was part of my quest to find durable and environmentally-friendly alternatives to common power tools. In the case of the Katanaboy, I was looking for a hand-powered substitute for a chainsaw. After about 18 months of owning and using this tool, I can honestly say.....it does not replace a chainsaw! If you want a tool that turns trees into firewood quickly and with little effort, buy a chainsaw. If you are like me and want to get a bit of exercise while doing chores, don't mind spending a little extra time outdoors, and appreciate effective tools, the Katanaboy is a fantastic choice. It is my primary firewood cutter, as I do not own a chainsaw. I cut a cord of old, hard elm in about an hour, with frequent breaks, although the more I use it, the fewer breaks I need. Most of the branches were under 8 inches in diameter, but I cut a couple of sections that were twice that size (it wasn't easy, but it was fun). I bought a second saw from another vendor for use at work, where part of my job is management of a nature preserve (which includes trail construction and maintenance). In the nature preserve (and at home), I prefer to avoid the noise and pollution of a chainsaw. Trail work volunteers are envious of my "samurai saw" and argue over who gets to use it first.Volunteers almost always bend the blades of my pull-cut saws, but none of them were able to bend the Katanaboy's blade. In fact, after extensive use, I haven't even come close. The saw's handle is comfortable enough. Since it's a pull-cut saw, most of your effort will be on the pull, so a straight handle works just fine (like a tug-of-war). If you pull by bending at your waist or even rocking back and forth on your feet, you can give your arms a nice break. The teeth are extremely sharp, but the locking mechanism has sort of a half-cock safety that minimizes the chance you'll get your fingers caught between the blade and handle while folding the saw. Interestingly, the back of the blade is a pretty effective machete and is good at cutting grass, non-woody weeds, and small dead branches (although this is obviously not its intended use, so be careful). It's fun to pretend I'm swinging around a real katana sword! If I had a big job to do, I would opt for a chainsaw. While I'm confident I cut bigger logs with the Katanaboy (or more than one cord, if I were in better shape), I really don't want to try. I prefer the Katanaboy for small jobs that can be completed in the time it would take to get a chainsaw ready, and for medium jobs that won't take too much time or wear me out. I also prefer its low maintenance, silence, small environmental footprint, and its aesthetic (the experience of using a quality tool, smelling cut wood rather than burnt oil and gasoline, and the sound of birds rather than a two-cycle engine). I am seriously considering buying three more for the family so we can have a nice family outing while getting a larger amount of firewood (and overcoming the saw's main shortcoming when compared to a chainsaw).

As a professional arborist this saw has come in clutch on some jobs but it god send when it comes to camping and cutting wood. The folding ability allows for the saw to store comfortable under the back seats of my truck so it always there when needed. I have cut down small tree (10-15 feet) and it did the job, but I would probably prefer a chain saw on any thing over 8 inch in diameter even though the Katana would work.
