I see talk about the pole saws. The Silky ones are really poor design. Clips don't hold and detent buttons don't stay in place. I've heard the newer, more expensive pole is a better design, but its a pound heavier than the Hayuauchi. I now own a Stihl branded ARS 20 footer...better tool for sure. The Zubat pole saw is nice, but the clips are the same poor design.
Re Corona handsaws, note my post from some time back. The new ones no longer are the same, handle is different, and prolly blade quality as well. Samurai makes the identical saw as the old Corona....and for extra $, the thinner, hollow ground Ichiban is a great blade...but I've broken two of them. Have to cut with finesse with them and then they'll work fine...prolly faster cutting than a Zubat and last a long time...till they break. I'm going to buy more Zubat blades for that reason.
