Here's a Kopis I made based on an illustration of a Kopis in "El Armamento Iberico” by Fernando Quesada Sanz. Im a fairly new bladesmith, so I kept it simple.

Hand forged a piece of 1084 to the rough shape and dimensions then finished it by grinding. Mild steel pin and JBWeld for the handle scale construction, water buffalo horn scales and a thin full convex grind at 20°

Overall length: 23.5"
Blade length: 17.5"
Mass: 475g
PoB: 4.5"
CoP: 5" from tip (approx.)
