I suspect these two are Bahco, they were my dads before me and theyve been well used and abused for at least 30 years. I used to take the small one camping as a kid with no idea about sharpening, edge profiles, how to use an axe responsibly etc
I'm kindof in the process of restoring them into decent tools though I havent got far yet. TBH while I have a lot of Bahco tools, they are not renowned for their axes and while these are perfectly good and usable they are not really comparable with the likes of GB which were a revelation to me, due to their thin edge. The edge is steeply ground and very thick on these Bahco's, they are not at all designed for fine work or carving but primarily for splitting I imagine, though a thicker edge would probably clear chips more quickly where thin axes can have a tendency to stick. I dont know how the edge oin these would hold up if they were significantly thinned down? I'd be interested to know if anybody has significantly reduced the edge angle on one of these.
These are just my musings I'm no axe expert and would be happy to be enlightened as to the benefits of various edge profiles on axes. I dont really use axes enough to have a definitive view on it.
