I heat treated a 10" O1 blade today the way I always do. Soak for 20 min at 1450-60 in my sugar creek kiln, and edge down into warm (110-120) peanut oil. The blade didn't crack :biggrin: it wrinkled :what!:. About an inch of the edge looked like a dog trying to smile. I had ground the blade to the traditional dime thickness - as usual. Also the edge didn't scate a file like it normal and there was absolutly no scale on the blade when it came out of the oil. I fixed the edge, cleaned the blade and tried again - same result.
Can anyone tell me what I'm missing?
