You have to use their blades in the cutter because the notches at the center of most blades will ruin the Martelli bolt.
joe's mom, they also stress to use their mats. Maybe that's why they dull faster. I don't have either one but when my bee met there, we had to use their mats and their cutters. I always wondered if normal blades would fit. Your description of the notches makes sense.
