Back in December, I bought a set of brand new 13-inch K Zildjian hi-hats. They sound great, but there's just one problem: The edges on both the cymbals are pretty sharp-- sharp enough to chop away at my sticks to the point where a pair of them will only last me 2 or 3 shows. I feel like I don't hit any harder than the average drummer and try to be as relaxed as possible when playing. Has anybody else experienced this issue? I also emailed Zildjian about the problem; we'll see what they have to say.
