Hello Everyone, I just finished up a small batch of carbide straightening hammers. These end up being roughly a 6oz hammer head with a 3/8” carbide ball pressure fit and glued into the hammer face. For anyone not familiar with this tool it’s for straightening hardened blades after tempering, you place the blade with the warp facing up on a flat anvil or metal surface and lightly hit the inside of the curve. The carbide slightly deforms the blade and causes the material to stretch and straighten out. I’ve used these to fix warps in carbon steels up to 66rc, stainless steels like aebl, nitro-v, and magnacut upwards of 63rc with no issues. You can either leave the dimples left by the hammer or grind them out they do not go very deep, the key for removing them is grinding equally from both sides of the blade after it’s been straightened. Sold out, Thank you everyone!

I have one already, but if I didn't I would grab one in a heartbeat. These are legit, and the best way to straighten a blade. GLWS Josh, great item to offer!

Thank you David, it’s one of my favorite hand tools in my shop and makes heat treating and straightening very efficient and low stress.
