The Logan 271 blade is the same size and thickness as the 270. The difference is that 271 has a single bevel, being ground on one side only. For use only with the 5000 8 Ply hand cutter.
The single edge blade can be better for cutting thicker board and tougher materials, such as cotton rag board.
Logan 271 blades fit the 5000 8 Ply hand cutter only.
Fitting instructions: the side (of the blade) with the ground edge, should be facing you, when fitted, and when you are looking at the side face of the 5000. In other words, the sharp edge faces out from the cutter.
