I'm switching to Slick Tricks.The owner of my local pro shop gave me one to try and was amazed how easy to tune it was and and how insanely sharp they are and even after a half dozen shots into a block target they seemed sharper than a new muzzy.
I was using Rage and get tired of replacing the o-rings that hold the blades closed, it's a yearly headache of looking for the dry rotted ones that won't hold the blades closed, not to mention that i got butterknifes that are sharper.
