Edge honing is vital in increasing cutting edge strength, as non-honed edges have a tendency to crack, gall, and crumble under the stress of dry machining. However, honing does reduce edge sharpness, which can increase heat generation during machining. The larger the hone, the duller the edge and greater the heat generated.
