Apache Revolver
History is filled with weapons that are best characterized as novelty weapons, such as the Blue Peacock Mine. However, the Apache revolver was arguably the most useless of all the firearms of this type. With a knife blade, a gun, and a pair of brass knuckles, it was obviously intended to be three weapons in one, but it was potentially worthless when used as any of those things, let alone trying to use all three at once.
The revolver had no trigger guard, so there was always a chance that it might accidentally fire. For some reason, the brass knuckle portion of the handle was made so small that only someone with very little hands could possibly hope to slip their fingers through the holes. The blade was attached very shakily and ran the risk of breaking off.
The gun was practically without a barrel and had no sight. Only at extremely close range would it have been successful. For safety concerns, you would need to store it unloaded due to the trigger guard's absence. And to load it required taking out the complete cylinder. Therefore, if you needed to use it quickly or from a distance, it was truly one of the most impractical weapons in history.
