Guess I never did thid proper when I signed up. My name is Corey Nilson from north central Nebraska. I ranch and have way to many hobbies. I love making things and I was hooked when I found this forum. I want to thank everyone for letting me be a part of it.
What I have is a large propane cutting torch. I heated the blade till it did not attract a magnet and then went straight to heated 10-30 oil. I do not have a hardness tester,but I tried a file on it and it seemed pretty hard. The file mostly just slid across.
