"Most Ridiculous Personal Weapon of All Time" Topic

Based on the video of a fully automatic Glock pistol with a barely 2-inch "bayonet" mounted on the end of it (from this TMP discussion TMP link ), it's time to nominate your choice for Most Ridiculous Personal Weapon of All Time.
The nominee must be a real, functioning weapon (for certain definitions of "functioning" and "weapon"), not something made up for a fictional film, show or novel.
The weapon must be a handheld object intended for a single person to use, with all components integral to the weapon— a control device doesn't count.

My nominee: The Apache Revolver, circa 1860:

Bring ‘em on, boys.

I always thought the "pepperbox" pistol was a strange weapon, looked too large to conceal and to fidgety to use.

The pepperbox was notoriously dangerous to the firer. It was not unusual for the remaining five cartridges to go off with, or just after, the first. That much explosive power could make the pistol fall apart.

It might work better if made with contemporary materials and at contemporary standards.

I think that the Sedgley OSS .38 was pretty ridiculous – a single shot .38 calibre weapon that was supposed to fire when you hit someone in the face with it

The Wiffle Bat.

I don't think the Wiffle Bat counts as a weapon, though it would be a ridiculous object to select as one.

Here's an odd one:

The Urumi— en.wikipedia.org/wiki/Urumi

Looks like a good way to cut off your own head…

The urumi is a specialized weapon. The article you linked indicated that it is taught last in martial arts courses. Any weapon, and many tools (the chainsaw comes to mine) when handled by an untrained idiot are dangerous. I wouldn't say the urumi is inherently ridiculous.

Cane guns. If you use it as a real cane, you are apt to bend, misalign, clog, or accidentally fire it. If you have to stop, maintain, and load it before firing, the point of having a concealed weapon at the ready is moot. It's just not a good idea, especially when there are so many other practical options for a concealed personal firearm.

I'll add the "rope dart" to the list, which appears to be related to a yo-yo, yet is loved by movie makers. (It features prominently in the recent Marvel movie Shang-Chi: Legend of the Ten Rings. (Good movie, somewhat ridiculous weapon.))
