quercus

I like all silky's mate... In fact we've got quite a lot of them.
-1 back up folding type in the rear pocket of my harness. + 1 extra for occasional extra climber
-1 sugoi for pruning (MY FAVOURITE)
-1 Ibuki for cutting branches when feeding chipper and for groundie.
-1 root cutter with diamond dust teeth tips for cutting of roots and dirty and sandy wood)
-1 fixed blad with double type edge for pruning fruit trees (rough and small teeth combined in one saw)
-1 small foldable pole saw for climbing (2 extension parts, for those buggers you just CAN'T reach, saw is very light and there are straps for hauling it) MY FAVOURITE POLE SAW
-1 hayate for delimbing the first 8 meters for takedown jobs (rigid, thick and strong but heavy pole saw with three extension parts)
-1 hayauchi for smaller pruning from ground or deadwooding with three extension parts(lighter then hayauchi but loses a lot of force in the bending of the aluminum tubing)

I like the fact that they cut really fast, and leave a silky smooth surface of the wound. 60 % of pruning I do is with the handsaw.And the fact that all parts of them can be ordered seperatly when something breaks. Gotta be carefull with the polesaws though. the aluminum profile can bend when it comes down along with the branch or when they get stuck in the cut. We've encountered these problems before. If you respect a silky, it'll last for decades.
