EXACTLY! I'm a former hardcore rockcrawler and now a wannabe desert racer(from the midwest....?) and I've ALWAYS cut my own tires. When BFG came out with the blank Krawlers it was like they heard my prayers.
Oh and knives take WAAAAAY too long on mtb tires and it feels like it actually distorts the carcass itself, concerned me about the the tires integrity, I found endcutters to be the method of choice. Like 10 minutes per tire for even a serious cut pattern, just go over it a few times dry before you even pick up the cutters. Don't want to mess up a pattern on something like that!
