I'm not sure of the question here. Scalpel blades are very different from razor blades. I would not use a razor blade to remove damaged tissue from a wound, nor would I cut parachute cord with a scalpel blade. Scalpel blades are honed to an edge and razor blades (utility blades) are ground to an edge. I carry both. I carry scalpels, sutures, forcepts, etc. in my surgical kit, and Razor (utility blades) with my light weight kit. Both for different purposes.
