I haven't started a topic on here before and I'm kinda new to the board, so I hope I'm doing this right. Anyway, I use Martelli Cutters - the company I work for sells them. They are extremely comfortable to use because they are ergonomically correct. However, after changing about 2 or 3 blades, it seems the cutter strips out. Has anyone else had this problem? Any suggestions? I've just about got to use this cutter because of being a rep but I do really like it.
