Probably nothing if it is a knock off, up to $300 if it is authentic. The brass knuckle ones are very common however, so I'm going to say an authentic one of those is worth a little lower than $200.
yes, 1918 LF&C mfg. trench knife. the handle can be removed but not recommended.
yes, brass knuckle trench knife made by L&FC (I think) in the US. Knuckle knife dated 1918. Although knuckle portion was removable, it generally was not taken apart. It was carried in a scabbard made for the knife. It is a collectable item...............
The 1918 US trench knife is worth around $300 if it is original, and depending on the condition. Poor condition really brings down the value. Beware though, there are far more replica 1918 knuckle knifes in the world than originals, fake ones have very bright crome blades, and some have the brass handle cast too small. I have a fake in my collection because originals are too expensive. The original sheath is quality made, the repro ones are cheep and flimsy. A repro is worth about 15-25 bucks.
yes the mariana trench is the largest in the world
A trench knife is a specialized knife made specifically for the close quarter combat on World War 1. Most of the fighting took place in narrow trenches or on "no mans land" a trench knife, which consisted of a brass knuckle with a long blade permanently affixed to it was a handy weapon to have. The trench knife doubles as a brass knuckle and a knife; with the knife securly attached to the user's hand, the enemy could not easily take the knife from the user. In trench warfare where firing a gun while in the trench could accidentally harm a fellow soldier who happens to be behind an enemy, a knife or bayonet was a safer means to eliminate an enemy.
