Those are sweet! I need to get those.
I noticed your Weaver Leather full-welt mask, too. They're big, tough and they'll cover most any felling axe.
They will definitely lift more than a standard wedge. I use them in tandem with plain ones a lot, since the hardheads are heavier and more $$. When the all plastic is bound tight, I can almost always get a little more with the hardhead.
Those weaver sheaths are pretty good. I like that they fit the big bits on Jerseys and Connies.
