Anyone recognize this mark?

I feel like I’ve seen that before but can’t think of where.
Feel like there was some historical significance to it but really don’t know.

Reminds me of a sword made into a Christian cross.

It is the maker's mark (?) on the back of the sheath to the smaller custom made knife in my first post. Hoping someone recognizes it and might could maybe give me a name to go with it.
