If I can split a pencil line with the saw, does it matter whether you want to call it a pruning saw? I tend to use it just for end cuts anyways.

I also use a chainsaw for end cuts quite often. The electric chainsaws are a little easier to handle because they're lower RPM and lighter.

I haven't tried to use an axe for a finished cut, but I use it all the time for roughing out housings, scarfs, lap joints, and tenons.
