Knife Sharpening
Precision sharpening using whetstones. Angle geometry (15-20 degrees per side), steel metallurgy (carbide structure, Rockwell hardness), grit progression from coarse (#220) through medium (#1000) to polishing (#6000), leather stropping with compound. The bevel becomes a mirror. Measurable results via paper tests and microscope inspection.
