According to Dr. Windrum, Kelly Yeaton identified this exact same knife as matching, in size, one he owned. Kelly referred to his as “an early prototype,” sent to him from Shanghai in 1934. (This turned out to be the knife known as the “Pilot Model.”) Our dagger is stamped on the tang as being made in 1933 and has a nicely turned walnut handle. Unlike later Shanghai daggers the handle profile is a full round in cross-section, not a flattened oval shape.
Our Walnut handled knife is the exact same knife illustrated in Windrum’s book “The Earliest Commando Knives,” page 23. A better photo of it can be found in the book “Military Knives: A Reference Book.” However, despite believing it to be a legitimate knife Dr. Windrum candidly states: “there is nothing about it to link it to a bayonet blade.” I am not sure what prompted Dr. Windrum to say this. I laid Pete‘s Shanghai dagger on top of an original, unaltered, 1888 Lee-Metford bayonet and the two are absolutely identical to within a hair’s breadth. It is my opinion that a skilled craftsman may have simply ground the blade a little thinner and in the process erased the hollow grinds and flat spot on the central spine of the original bayonet blade. I have proof of this happening in several of the half-converted knives I own. Of course it is also possible the maker simply traced the tip of a bayonet blade onto a blank piece of steel, using it as a pattern for this blade and others.
