Stop Sharpening Around the Problem Full Bolster Correction [4K]

A full bolster on a German knife is a ticking clock. Every sharpening cycle without proper maintenance accelerates "bolster droop," eventually creating a clearance gap that prevents the heel from contacting the cutting board. If you are only apexing the edge and ignoring the bolster, you aren't sharpening—you're degrading the tool's functional geometry. This session demonstrates the systematic correction of bolster geometry using a 2-inch machine. I detail the transition from aggressive reprofiling with worn 120-grit ceramic belts to creating a seamless convex grind on the slack portion of the belt. We address the "square bottom" aesthetic failure by re-establishing a professional radius and finishing with non-woven nylon satin belts to erase machine marks and restore factory-grade aesthetics without compromising the primary blade's heat treat. Whether you’re a professional sharpener or a craftsman refining your bench work, understanding cross-sectional geometry is non-negotiable.
