Many so-called knife experts have heralded the "wear resistance" of a steel as the key to edge retention. This may very well be true if a knife is designed and intended for the cutting of soft materials ONLY. However, we have never inspected a dull knife and found the edge to be perfectly smoothed away, like a ball bearing. Instead what we find are microscopic chips where the edge has broken or chipped away like glass after having impacted against bone, gravel, or other hard surfaces. This micro chipping dictates that the edge be reground during the resharpening process, which will ultimately lead to a thicker edge and a radical change in overall blade shape. |
