Mine are a size 7. But they have been various sizes over time. BM uses whatever bunch they have at the time because its cheaper to buy them in huge lots. The next lot could be a size 8, etc. They do however offer the new Torx bit Kit. See Mark at MJS Knives. He had them last I saw. Take note, they don' t contain a 9 which is what at least one of my BM needs. What gives BM??
