Are D.W. ENGEL Knives a Thing?

[TheSingingSharkOfWhales]

I was looking into selling this knife, but google was not being the least bit helpful in finding any other DW ENGEL knives. Has anyone seen one before?

I like everything about it except the holes.
Homemade? Maybe he only made 2...?
Where did you get it? How old is it?
Someone will know the answers.
