That is one of the reasons I strip all the varnish off as well. You expend so much energy just trying to hold on to the slippery varnish, it tires you out faster and there is the blister issue. I prefer wooden handles over metal and fiberglass anyway. I think they hold up better and when they do fail, are easier to replace and cheaper than buying a new tool.
Its a wood handle, nice shape actually. Just yea varnish sucks, why do they do that?
I have tightened up some old axes in linseed oil soak.
I am not a fan of fiberglass either. Hence avoid fiskars. I dont like the metal on em anyways, too rigid and brittle....as if they made the whole thing out of what should just the edge.
Not a fan of that do not strike warning either, real axes can be hit with a sledge, or flipped around and used as one.
I am a bit of an axe snob.
I can be a real axehole sometimes.
Big fan of metal collars too, I tend to bonk the neck after a few beers and a little cockiness.
