Currently unidentified trench knife. Aluminum grip, sharp double-edged steel blade. We know we've recently seen this distinctly shaped trench knife on line or in a book, but after a quick search through several bayonet and weapon resources, the memory still remains elusive. Plese email if you can help identify this knife.
