I'm shooting Muzzy 3 blades, just because I have 6 of them with replacement blades and they were given to me.........but I'm REALLY tempted to try these Killzones after reading about them here and on other sights. plus they appear to be significantly cheaper than the rage Hypo's...
Place I buy from has them both at the same price. Thing with the Hypodermics is you have to replace the little clips all the time that hold the blades in. Killzones have an internal clip that is only replaced with a new set of blades. We cleaned up my Son's and resharpened them with a special tool I have and they are ready to go again.
