Next time: the wife will be standing there in the kitchen, as you go to put the blade over the flame. You turn to the stove (or othet flame producing device....what
did you use?) and so now with your back to her she cannot see that you are actually not putting the blade into the flame....Put on a good show- "Wow, now THAT's getting hot! Ooooh, I almost burned my finger there.." etc....
As a matter of fact, maybe you can send your razors off for a professional honing, and tell her the $20 is for autoclaving and sterilization?
