I can not possibly imagine that boiling water would affect the temper of a knife. Another manufacturer of carbon steel knives told me that I would have to exceed 850 degrees F before I started to lose temper with his blades. This was a topic of discussion because people were asking about using one of those baked on finishes like Kalgard (sp?). He was more concerned about damaging the micarta than the blade.
