Nice blade bud although you state self defence recurve/inside curve blades depending on steel I find can be good for feather sticks , shavings carvings etc.... But this would work well similarly to the style of ma that karbits are used for.
Wrist swipes , releasing from grips etc what are your costs for something like this if I may ask thanks.
Edit: I think a sharp top side would work well due to the depth of curve on the inside.
