What is a recurve edge?

Instead of a knife’s cutting edge that goes straight from the handle and then curves up toward the tip, the recurve edge dips a bit before going up, creating a mild “S” shape. If you look at my logo up top, you’ll see an example of the recurve. You can find—or create—recurves on most types of grinds. It’s harder to sharpen because you must reorient your tools, but the recurve generally makes slicing and hacking easier.
