Hat tip for Wolf Ops for heads up, and thanks for Silver-Otter workshop for digital paintwork (which is significantly worsened later with my crooked hands).
My idea of DPSK, deft practical small knife, become more definite. As I saw Lone Wolf (Benchmade) Mountainside skinner – it seemed nearly perfect to me. Just angle between blade and handle need to be changed, and axis of handle (blue line) raised above axis of blade (red line). Look at the concept picture.
