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.

With just firm finger pressure, you can open and close the knife thanks to
its snap-fit closure. Snapping the blade is easy, too — the knife has a built-in
blade snapper tool. Use the knife to cut through packaging, shrink wrap, vinyl,
window film, wallpaper, caulking, foam board and other materials. (A-1, #5023)

Good For: Applications such as paint, window film and
packaging. Cuts tape, shrink wrap, wallpaper, film, cardboard, caulking and
more.
