Brass Handled Knife I.D. Help Please

[Clubs & Arrows]

Hello.
I picked up this blade at an estate recently, and was wondering if anyone could help me identify it. The overall length is 13 1/2", I don't see any markings, and the handle is pretty heavy with makes me think that it is solid instead of hollow. Is it a trench knife? Any help would certainly be appreciated.

Best regards,
Joe

Unusual, perhaps it is a mid 20th century divers knife. I have seen many with brass handles.
