Hi, I’m new to the forum and knife making. After years of watching forged in fire and other blacksmithing shows I decided I would try making a knife of my own. I bought a billet of Damascus off eBay and set to working cutting to my design. I only have access to basic tools such as hacksaws, files and an angle grinder. I have gotten my shape cut and bevels started and have left the cutting edge about 1.5 - 2mm wide as this is what I read it would need to be for heat treat To stop warping. I would be sending the knife off for heat treatment as I don’t have the equipment for this. What I am worried about is once hardened will I be able to take my bevels down to a cutting edge with only hand files or will the metal then be too hard?
