Exploding Knives, and Other Hazards of Kashering
Let me just start by admitting that I probably didn’t really need to put the knife directly on my burner. But it was the first time in a very long time I was kashering anything, and I had conflicting guidance from my rabbi and my mother, and I thought I needed to drop a hot metal object into my hot water urn to make it kosher for Pesach (I was totally wrong. Do not try it at home.).
