Final Grind before Polishing

Once the nails were heat treated, the blackened surface discolorations and grime are ground off. The knifemaker's aunt spent time today grinding the blade and spine edges again as well as the sides and butt of the handle.
They are ready for the knifemaker's dad to polish and buff them to a blistering sharp edge. When the knifemaker's aunt asked why she couldn't polish and buff the nails, the knifemaker's dad raised a sinister eyebrow of disbelief and said "No, those are the two most dangerous machines in the shop and only I operate them." So, there you go. The knifemaker's aunt is relieved of what is probably a most dangerous part of the process.

A surprise bonus on this July 4th day.
