So, this is the En - Nep I started some time ago. Made from ancient (150years+) leaf spring I found in the woods, 10,4 cm long, 4mm thick.
The layout is drawn along a whiplash line making it very whippy indeed in chopping and, together with the recurve edge line, makes for a very slicey blade in spite of the thickness.
The balance point is on the index finger. It feels very light and dexterous and point-centered.
Theoretically you could whirl it around your index finger. I tried;-).
The blade tapers towards the tip. Scales, by the way, are elk antler, fitted with mosaic pins. The bevel is a high convex one, and the temper is---selective of course.
