I have tested a lot of my "failure" handles to see what kind of force it takes to break the epoxy butt joint,I have never tested how much heat they could take.I had to remove a Wa handle to regrind a blade so I took the opportunity to heat test the epoxy.So I wrapped the blade in a wet rag,clapped it in the vise and busted out the heat gun.I was expecting to just heat the wood up and slide the handle off the tang but that was not the case.I heated the wood up for a very long time slowly for 20 minutes,the wood was hot enough to burn me through a leather glove but the handle still did not come off.So I just kept heating the wood up for 10 more minutes until it was just about to catch fire and still the handle would not come off.In the end I had to cut off the chard chunk of wood(sorry mark) and had no true heat failure off the epoxy holding the tang in.
