Roland Sasser, in Georgia USA, sent us an S.O.S. He was looking for a professional gap-knife that would help him prevent ugly zig-zag cuts on things like car doors and fuel-filler doors. So we invented the SasserCut series for him.
This positively driven, steel-bladed knife with a specially shaped support-wheel comes in three different versions, each exposing a different length of the blade. The larger wheel (6.5) exposes less blade, while the smaller wheel (4.0) exposes more blade.
