In a preferred embodiment, a six-cutting-portion featured blade is employed. Each point of the six-cutting-portion featured blade features two distinct cutting portions, for a total of six cutting portions located on a single blade. The blade can be rotated about a central axis to expose new cutting portions as old portions wear and dull. In another embodiment, a single-edged blade featuring two cutting faces is housed in a knife handle. The blade can be flipped when the first portion is dull or worn to expose a second cutting face. The handle may optionally include a storage space for storing additional blades.
