I took the the blade to some 600grit sand paper, then stepped up to 800grit & then up to 1200grit. It is super sharp now! A lot of them lines disappeared on my split leather now.
I think the blade had some minor imperfections, but is great now. I think with time it will get better.
I'm fairly sure this is a cowboy 806 leather splitter, or a knock off of a cowboy 806.
I highly recommend it, if money is a concern. It is the Yaetek brand from amazon & seems to work great. It only cost $159.99
