I was hoping to replace a woodzig that I bought some years ago.
These blades are a bit too aggressive. I.E.when used in a handsaw, pull force required on the cutting stroke is really a bunch.

Blade is TOO aggressive. Hard to use as a result. Would not work well on a pole saw at all if attempting to cut on anything that had any give I.E. cutting small branches.

Purchased to replace a blade on an old tool, I knew I would have to re-work it a bit. The metal was fairly hard and resistant to drilling and filing, that was a good sign. It is a bit stiffer any the original blade but that makes it easier for me to use. After at least 8 hours of use, the blade is still very sharp and cuts quickly.
I'm a member of my town's conservation commission and spend plenty of time clearing/trimming trails. I am very happy with this blade.

Replaced the very dull blade in my extendable Fiskars trimmer. Works much better than the dull original although I think this one will likely only last a year or two with all of the trimming needed here in Florida.

Got this to replace the flimsy blade on my cheap tree pruner. Had to drill some holes in it to make it fit, but it saws through branches like nobody's business. And the blade is thick enough that it won't flex sideways, as my old one was always doing.

Awesome blade! Cuts faster than any pruning blade I've ever owned. I have a Carona brand pole pruner but they no longer sell replacement blades for it. I bought this Fiskars 15" (same length as the Carona blade). I used one of the existing holes and merely drilled an extra hole so I had two holes that lined up with the two holes in my old blade where they needed to be and , viola!
