Yep, I agree with you, not an easy thing to improve a tools that has evolved for thousands of years. Mostly end up with gimmicks that separate the uniformed from their money.speaking of which, the lever axe. i saw a post on one of these a few months ago, i'd heard of them and not a fan.
one person commented "finally, an axe that uses physics" and that speaks volumes about the attitude people have. rather than flicking an old or decent quality axe, they want the tool to do it for them with no regard to skill or comfort.
they used to be $300 at least, apparently they flopped hard. lowes now sells them for about $70
power tools have spoiled people. they dont even want to invest the $50 bucks and a few hours to learn how to sharpen things.
generally when tools have gone unchanged for centuries, there is no improving it
I have been rewarded by those that were to incompetent or lazy to hang an axe and just went to town and bought a new one rather than change a handle and cursed by others that incompetently sharpened their tools on a bench grinder.
