[Bigduck1]

Happy New Year to you all! Starting off with another mystery knife that I need your help with to identify. Is this military or what else?? Please see photos. Appreciate any help you can give!

"Theater made" ? nice handle. J.O'.

It’s an odd find for sure! It is very well made so I don’t think it is “Theatre”? The handle is reminiscent of military use. The handle is tight with Brass and I think Bakelite or wood ring spacers. Look more Bakelite than wood. The Blade is obviously well used but maintains a very sharp edge. Filet blade perhaps? This is a tuff one to figure out. There are zero identifying marks anywhere that I can find.
