I feed argon into my Paragon to prevent heavy scale. The result is a light, thin, soft scale. I grind my blades after HT. Doing that removes the thin powdery scale and and surface decarb or slight pitting that might have occurred. It also saves a little time getting to the quench since I don't have to remove any foil (coating the blade would also have that advantage). Argon is cheap and apply it to the furnace requires only a cheap regulator available on eBay. Lots of ways to skin this particular cat ....
