So I have been bitten by the axe bug, and I have been on the search for a "project". I recently picked up a kelly perfect double bit for pretty cheap. It appeared to be in good condition the bits weren't badly chipped. There was a nice substantial layer of rust and the level of pitting couldn't really be seen, but like I said the price was right and if anything else could find its way on the wall of the man cave. So after a couple days in a vinegar bath and some attention with a wire cup brush I wound up with this.
There is some pitting but I don't think its anything too serious. What has me puzzled is the shape of the bit edge. I noticed when I first got it that the toe, and heel weren't symmetrical. It looks like the heal is further out than the toe. SO I originally thought that someone might have messed up sharpening it along the way. Well I was browsing the online auction and noticed another kelly double bit with the same asymmetry in a little worse condition. Seen below.
So my question for you experienced collectors, Is this a particular pattern or shape? Or did two people mess up the grind on their axes the same way?
Is this a viable head? Should I try and grind the edge symmetrical?
Thanks for the help.
