I just finished 2 plasma cut blades. How should I go about heat treating the blades after sharpening? I only have an oxy/acetylene torch to heat the blades so how should I go about it. The blades are made of mild steel about 0.77 in wide and about four in long. I would upload a photo but I forgot my USB cord.

Hi all, I've got some questions about normalizing before a quench. In "The Complete Bladesmith", Jim Hrisoulas cautions against leaving steel for too long above critical temperature when quenching, and against quenching multiple times, because the metal is subject to rapid grain growth above that point. I've seen other sources talk about normalizing the steel before the final quench (often repeatedly) to relieve stress and refine the grain. As I understand it, normalizing (a basic 10XX carbon steel) involves heating the steel above the critical point and then letting it air cool. H

Properly heat treated this steel is great! It cuts very well. It has good contrast and is easy to etch. I know many knife makers who prefer to work with this steel! This is how we heat treat our stainless steel Damascus when the layers are AEB-L and 301. HEAT TREATING: Preheat furnace to Austenizing temperature Place blade in furnace Allow furnace to cycle back to Austenizing temperature Soak for 15 minutes Quench in oil Temper 2 times for 1 hour each time Quench in liquid nitrogen for 4 hours and re-temper 1 time HEAT TREATING TEMPERATURE MATERIAL AUST

Currently in history, I'm studying the Homeric period, and especially the Epics, the Iliad and the Odyssey. I got a reading assignment, chapter 9 of the Odyssey, the situation with the Cyclopes. I will say it's pretty gruesome at places, but at the area where they're blinding the Cyclopes, I found some interesting text. I'm not quite sure how exact the text is, as it gives Roman names instead of Greek, but this is supposed to be a very close translation. The thing is, was heat treating as such developed by the time of Homer (7th and 8th centuries B.C.)? I do know that Iron would have been w

To preface i want it known that yes i am aware of parks 50 being the ideal quenchent for simple steels however im trying to get a few knives done before next week as they are for a school project so im on a time constraint as far as getting a batch of parks 50 and also my budget will not allow that at the moment. So i am moving my attention towards oils available in grocery stores i know canola oil is a favorite among many however next to a bottle of canola i noticed a bottle of this grape seed oil. i sloshed both around to see how they compare in terms of viscosity and it appears that gra
