When confronted by a henchman in a scene from the film, Raiders of the Lost Ark, Indiana Jones (played by Harrison Ford) notices the fancy blade-wielding skills of his opponent. Unimpressed by the acrobatics and the fancy blade-twirling bad-guy, Indy retrieves his revolver from his holster firing a single, well-placed shot, dropping the adversary nonchalantly.

I don’t profess to have knowledge of the type of sword wielded by unimportant character in that film nor do I have expert knowledge in the field of military edged weaponry. What I do have in my scabbard is the ability to use the research tools at my disposal – which comes in quite handy when given an arsenal of knives, swords, bayonets and bolo knives.

The scabbard and blade of the M1910 bolo.

A few years ago, I was asked to catalog and obtain value estimates of some militaria pieces that were part of a family member’s collection. He had passed away some time before and his executor was carrying out the responsibilities of handling the estate. In the previous years, I had only seen a few items from the collection so I was surprised when I saw what was there for me to review. After completing my work on behalf of the state, I later learned that I was to receive some of the pieces that I had appraised, much to my surprise.

Of the blades I had inherited, three were quite unique, different from the rest of the pieces. Two of the three blades were almost identical in form and the other was a slight departure from the others. What set these blades apart from the rest was machete-like design with more size toward the end of the blade, giving the blade a bit of weight toward the end of the blade rather than at the center or toward the hilt. The design of these blades were fashioned after the weapon of choice of the Filipino resistance fighters from the revolt that started at the end of the Spanish-American war in 1898.

Known simply as bolo knives, the U.S. military-issue blades were less weapon and more utilitarian in function.

Now in my collection, the oldest of the three knives is the M1904 Hospital Corps Knife. Though many people suspect that the broad and heavy blade was important to facilitate field amputations, this thought is merely lore. Along with the knife is a bulky, leather-clad scabbard with a heavy brass swiveling brass belt hanger. My particular example is stamped with the date, “1914” which is much later in the production run. The M1904 knives were issued to field medical soldiers as the United States entered World War I in 1917.

The second knife is less bolo and more machete in its design. The M1910 bolo was designed and implemented for use as a brush-clearing tool. Some collectors reference the M1910 as a machine-gunner’s bolo as it was employed by the gun crews and used to clear machine gun nests of foliage and underbrush. My M1910 bolo is date-stamped 1917 and includes the correct leather-tipped, canvas-covered wooden scabbard.

The last bolo in my collection is probably the most sought-after of the three examples. Stamped U.S.M.C. directly on the blade, these knives were issued to U.S. Navy pharmacist’s mates who were attached to U.S. Marine Corps units. This detail leads many collectors to improperly conclude that the markings on the blade clearly indicate that the knives were made for the Marines. While this is indirectly true, the U.S.M.C. markings represent the United States Medical Corps, a branch of the U.S. Navy. On the reverse side, the blade is date-stamped, “1944” making the blade clearly a World War II-issued knife.

Although the blades are relatively inexpensive, they are considerably valuable to me as they come from a family member’s collection and were handed down to me. Though I do not have a desire to delve too far into edged weapons-collecting, I added to my collection by acquiring a pair of US Navy fighting knives to round out my collection. In future posts, I will cover these two types of knives, swords and sabers and even a few bayonets.
