The longtime seller “A” has been fully remodeled and now called “A-1”. The thin-model cutter, featuring a full-scale pocket-clip/blade snapper and carbon-like engraving on handle, fits hands and pockets perfectly. Thanks to its special fine control Auto-Lock slider, the sharp angle SAB/DKB blades are its official spare blades along with the standard AB/ABB blades. For both left- and right-handed users.
