Without proper self defense training, and compared to having nothing, all self defense tools have some merit. Where these tools vary is in their respective design, methodology of use, and legality.
DESIGN:
The most obvious difference is an aesthetic one. MUNIO is hands down much more attractive looking than any kubotan or monkey fist. In fact, MUNIO’s stylish, innocent looks intentionally soften its raw functionality for self defense. Now if you happen to be the tough-type, you might think you don’t care how bad-ass your self defense tool looks, but that can be a critical factor for many others. Can you get your loved ones to ACTUALLY carry a self defense tool on a regular basis? That element of personal appeal is so, so important, because no self defense tool really works at its maximum if it isn’t ready to use in your hand, so its gotta be something you like. That’s why MUNIO’s sleek shape and designer artwork were intentional from its conception, not as an afterthought.
METHODOLOGY OF USE:
All 3 tools, when held properly in a hammer-fist grip, and used for self defense, have the potential to disable, and inflict serious pain upon an attacker.
MUNIO is a stylish form of a kubotan, or force multiplier tool. In fact, with all due respect to Takayuki Kubota, the inventor of the kubotan, MUNIO has been nicknamed a “flat kubotan” for good reason. Both MUNIO and a kubotan can use both ends as defensive options, and are both held with a “hammer fist” grip with the striking end below the little finger. However, the standard rod-like shape and length of the kubotan has additional applications to submission, pain compliance and joint locking techniques typical to trained law enforcement for criminal apprehension. On the other hand, while some martial artists do use adaptive joint locking and pressure point tactics, MUNIO was specifically developed for the kubotan’s basic striking and whipping motions that are instinctive to practically everyone, and do not necessarily require any specialized training. Ironically, even highly trained martial artists have confirmed that they prefer the simpler basic striking options that MUNIO provides, rather than a kubotan. Additionally, while a kubotan’s blunt, domed or pointed end can be used like a MUNIO, its keyring side typically has less range than MUNIO. MUNIO’s standard 3-ring configuration gives it more range and snap making it more effective for striking an attacker with your keys. Of course, anyone with a kubotan, or MUNIO, can add length or mass onto their keyring(s) at their discretion if they feel it makes it even more effective for them.
The monkey fist relies on a powerful, swinging motion to deliver its strike. While not as overall versatile, a monkey fist’s metal ball can cause significant pain and damage depending on the power and speed of the swing, the size of the ball and the area struck. Depending on the chosen length of paracord connected to the metal ball, its striking range is much greater than a kubotan and MUNIO. However, that length can become problematic depending on your skill level, and unlike both the kubotan and MUNIO, a monkey fist may be extremely difficult to utilize against certain attacks, including common “abduction” grabs over the arms from behind.
LEGALITY:
MUNIO has no legal restrictions and can be carried openly everywhere. MUNIO will pass through TSA airline security checkpoints and can be carried aboard all flights. After all, its just a designer keychain, right?
Kubotans appear to be legal in most U.S. jurisdictions, but are definitely prohibited from airline carry-on by the TSA.
Monkey fists appear to be legal in most U.S. jurisdictions, and may be prohibited from airline carry-on by the TSA. Depending on the size of the metal ball, a monkey fist can be classified as a sap or blackjack, making it illegal.
Use your best judgement. Consider putting them in your checked baggage if you are traveling by plane.
Be advised that the legal status of self defense tools is subject to the ever changing world of government interpretation and regulation, and therefore its status may change from permitted to prohibited at any time. If you have any concerns, please check with the proper authorities.
