If I had a decent wheel grinder I’d think about making one out of a drywall hammer. I think you’ll be pleased with the Estwing. It’s a solid piece of gear. It ain’t a SOG but 2 of those weren’t in the budget. LOL.
The edge needs a bit of work but some elbow grease and a file takes care of that.
Made a lot of GOMK’s (get off me knives) for friends and family the last 14 years.... simple durable cheap and deadly . Not one cost me more than 10$ tops to make as gifts, Crude, ugly but functional for purpose intended.
GOMK’n !!
