Replica US Model 1918 Mk 1 Trench Knife. Based on the original patent blueprint. Can be printed in full tang or half tang version for smaller printers. Prints in parts to make painting and weathering easy. With unmarked handle, as there are many historic engravings possible. You could add your own engraving with a Dremel if you wish to do so. I printed the model at 0.15 mm layer height, but up to 0.25 mm should work just fine.
