Hi there, So I've just started out knife making and I think I overheated the blade during heat treatment. It has left it with some pitting as you can see in the photos, I was wondering if I have damaged the steel significantly or whether it is still use able and just affects the finish? Thanks
Hi everyone, I have seen on several you tube videos that people only bring the blade section up to red hot before quenching but the full tang of the handle is not red hot ?

He turned me on to the idea of injecting argon - I guess it's a fairly common practice in industry. My kiln is a Paragon 24 with a digital controller. It's chamber is 4 x 4 x 24, and it's pretty damn tight as far as gas leakage. I bought the Paragon Argon Injectio
Hello. I'm new to the forum, and relatively new to bladesmithing. At least new to creating knives with a little bit of knowledge. A friend of mine is using my forge (and what little I know) to make a Tai Chi sword from a piece of rebar. We first flattened it (meaning I held it and he did the beating--it's his sword, after all), straightened it, and he has been working it over on a belt sander to clean it up. I know rebar isn't the greatest steel for a blade, but it's got some spiritual significance for him. I understand how to harden it, but how do I temper the center of the blade with
