This is the perfect, economical tool for removing those stubborn retaining clips found on rim cylinders and profile cylinders. This tool is originally designed as a plexi-glass cutter but it has a durable blade that is the right thickness and the right angle to get under those C-Clips to gently remove them without sending them half way across the room. Pull one side and then the other and the clip will come right off. The blade folds into the handle for storage so you can safely carry it in your pocket. Also, the tip and the beveled edge can be easily rounded off with a file or grinder if you want to eliminate the pointy end. This thing really works!
