Recently I took my Yard Hook and ground down the hook.Not all the way off but really it ended up looking almost exactly like a Yard Guard,I'll post pics as soon as I get a chance.Anyway I noticed that even though I was getting a steady shower of sparks,when I touched the steel where I was grinding it was only alittle warm.Is this stuff heat resistant? <img src="/ubbthreads/images/graemlins/ooo.gif" alt="" />
