Sheath for curved knife?

[DaleksInc]

Recently, I found this knife for cheap at an estate sale: https://imgur.com/a/dktTmFO

I would like to make a sheath for it. However, I am not sure how to do so. The designs I have seen in the past fold along a flat edge, but neither the top nor bottom edge of this knife are flat.

How would I go about constructing a sheath for a knife like this?

Just do a 2 piece sheath with a front and back panel and a welt running all the way around. And it can be whatever shape you need.

You would make a sheath for that knife about the same way you would make a sheath for any knife.  Trace the shape and go from there.  The blade would follow the shape of the channel inside the sheath.
