i know there were issues on blade sharpness a while ago, but have heard they fixed the problem and are now scary sharp, like YooperMike said. My question is, are you guaranteed to get the new sharp blades in every package of ST's no matter where you buy them? I mean, is there any chance you might get some old ST's where the blades werent as sharp? Sounds like a dumb question but i just wanna make sure before i buy them.
