Answer 1

It’s the handles. Sure they can get dulled by banging around, but you can always sharpen them. The high temperatures are very bad for wooden or composite handles and will eventually cause them to split or break. (Okay you can always replace the handles, but that’s a lot harder than just sharpening.)
