jmccustomknives Posted June 4, 2012 Share Posted June 4, 2012 More than likely, L-6 if the tips are carbide. If the tips aren't then some kind of HS tooling steel. Sometimes those companies have there own steel formulas. L-6 can make a really tough knife, it's one of my favorites. Quote Link to comment Share on other sites More sharing options...
Rich Hale Posted June 4, 2012 Share Posted June 4, 2012 For blades made to have teeth added on later they do not usually spend the money for a really nice steel for the disc of the blade. For blades that are made to cut wood and the teeth are machined into the disc the steel is really likely to make a good knife. I have used a lot of band saw blades for knives, they came from wood saw mills and no added teeth. I have always heard they were either L-6 or 15N 20. in any case they worked fine. I hav e also bought the two steels new and they seem to work and act just like the band saw blades. There are some shop tests you can do to see about how well they will do in a blade.:spark testing is one. but it takes a long time to really rely on. .And you must have a sample piece of material to compare it to. you can also do shop tests to see how well it works as a blade, Check the testing of blades as recomended by the Ameerican Blade Society. If you do any of this. Keep accurate notes so you can repeat each of the succesfull methods. Quote Link to comment Share on other sites More sharing options...
lab Posted June 4, 2012 Author Share Posted June 4, 2012 i have made a few knifes out of them. i have to heat to cheery red and cool down slow before i can drill Quote Link to comment Share on other sites More sharing options...
jmccustomknives Posted June 4, 2012 Share Posted June 4, 2012 That rules out any of the "voodoo" steels. HS steels don't aneal down that well. I'd bet L-6. Here's my formula. Heat to non-magnetic, quench. temper @ 400F for an hour. Quote Link to comment Share on other sites More sharing options...
MRobb Posted June 5, 2012 Share Posted June 5, 2012 jmc, what do you quench the L-6 in? Air, oil, water?? Thanks Mitch Quote Link to comment Share on other sites More sharing options...

jmccustomknives Posted June 5, 2012 Share Posted June 5, 2012 I use oil or a version of "Goddards Goop", 1/3 pariffin wax, 1/3 hydrolic oil, 1/3 vegitable oil. That stuff stays solid, it's great for smaller blades. Quote Link to comment Share on other sites More sharing options...
