Of late, on the nights I can't sleep, I try to find something productive to do; sort brass, clean the garage etc. Tonight's "sheep" are whetstone strokes. I've always enjoyed sharpening my knives, I think its the repetitive motion and the sound. It takes much longer than it used to. I have to stop and let my hands and forearms rest but it still zones me out. What do ya'll do on the nights you can't sleep?
