It can dull your edge, cause pitting, and damage the structural integrity of your knife. When we plot toughness vs edge retention on a log scale instead we get a straight line that is a better visualization of toughness differences. Most production knives are more than thick enough at the edge to accommodate a regrind to significantly improve performance, and its a lot cheaper than buying a new knife a lot of the time. In a pocket knife the total amount of steel is rather small. And below shows a chart of carbide hardness, the equation we created to predict edge retention based on edge angle, hardness, and carbide volumes, and then the chart showing the good correlation: TCC (mm) = -157 + 15.8*Hardness (Rc) 17.8*EdgeAngle() + 11.2*CrC(%) + 14.6*CrVC(%) + 26.2*MC(%) + 9.5*M6C(%) + 20.9*MN(%) + 19.4*CrN(%). The most traditional models of pocket knives have different parts, such as the handle and cutting performance. On the flip side D2 steel is much harder than other steels in this category such as 154CM or ATS-34 and as a result holds its edge a little better. This is a bit of a guess because I cant find un-notched Charpy data on it. Not impractical fantasy knives, but these two knives that have a col look to them.
