So the last night I found myself slightly intoxicated, and my wife decides that the smart thing to do is hide my knives..... Understandable.... But she decides that the oven is the best place for them..... And then forgot about it. When does she remember you ask? About 45 min into cooking her lasagna. Sheath is completely melted, but amazingly no damage to the micarta. Just thought I'd share. Oh, and one question, do any of you think this will affect the blade tempering in the long run?
