Well, I heat treated 2 O-1 blades and 2 1095 blade with success today! they take and hold a great edge. I used an oxy-acetylene torch, quenched in Vege oil. just gotta temper then in the kitchen over, finished them up, and put handles on them! Consequently, I will get pics up this weekend or early next week and 2 of them will be for sale, hopefully! The ones that might be for sale are 2 of my first knives I ever made, so the plunges and grinds are a tad off, but they will still look nice and cut!
