We are accustomed to seeing knives with a flat ricasso, a small choil and a plunge cut where bevel begins. I understand that this is a distinctly modern design detail. Some of youse who are into historical accuracy and period pieces can correct me here, please. The knives I make have a choil, but I forge in the main bevel, so the ricasso has a taper to it, not flat, and I use the choil to make the transition from edge to no edge; no plunge cut. Savy? Any pointers on correct historical practice? Thanks in advance.
