The KnuckSlap™: A New Take on Knucks

Michael Janich explains and demonstrates the concept behind his new KnuckSlap™--an evolved modular brass knuckle design that combines a classic two-finger knuck with a palm sap. The result is a weapon that can be used to punch, slap, and grab with crushing effect.

The KnuckSlap™ concept was created by Michael Janich. Mark Olson of 5x5 Combat Soltions then took Janich's original wooden model and refined it in CAD to yield a finished, fully engineered design. Mike Mackin of Spectrum Energetics LLC then executed the design in 6061-T6 aircraft aluminum.

P.S. The original name of this product was the "KnuckSap," however, several days before its release, another company revealed a different product by that name. Honoring their first commercial use of that name, we changed gears and christened ours the "KnuckSlap." Nevertheless, if you hear "KnuckSap" in the video, just imagine you hear an "L"...

I'm not gonna water it down; Mike is gold. His mind and work have empowered me, and I am so grateful. I do MBC drills daily, and hope to one day own all of his knife designs. I will be carrying one of these to pair with my defense blade.

[scottlawrence]

I like the versatility of applications it provides.

[TommySalami]

This is a really clever design. Well done.

[PeterPan-kzsi]

Not sure the legal parameters/ but this looks effective another advantage this may have over a palm sap is it’s ability to stay in place when slapping.

[frankiehernandez]

This is well thought out in true MBC style.

[qodeshymchurchwell]

Are you freaking kidding 125 bucks. I can just about get a gun with that.

[martinm.]

I want to see him actually hit something solid without hurting his hand. Then i will be a believer.

[INSDG]

Make this in a hard plastic to reduce weight and pass through metal detector and you have GOLD!

[entheogenocide]

Very cool. I've always thought 2 finger knuckles are way better. This is an excellent upgrade

[davyjones]

i can see this flying off in a high adrenaline moment when you are trying to slap someone

[RealFauxRogan]

Cool looking implement. But it still amazes me in the era of MMA to see slap happy arm strikes.

[bevbiltgarage]

Even though it's a small development of the original design it's a far more effective EDC that you can use in so many different ways due to the excellent shape and size. How can I get hold of one, I'm in England
I can see a decent open hand slap to the ear will be a serious deterrent to put an end to most situations escalating into a physical confrontation. And due to the size of it and striking quickly most people won't have a clue what just happened

[thegiftedone]

I love it! I’m buying it! Brilliant!…..is it legal in California?

[Kevin_drinks_Lead]

You can tell that non of them knows how to fight

[OOOMDW]

Does it Come with 1 or 2 ... 1 for each hand ?

[austinpundit]

The ever innovative MIchael Janich strikes again! (So to speak...) One question: is it a knuck sap or a knuck slap?

[eugenevictortooms]

If you tried to slap with that, wouldn't it fly off your fingers?

[shanemitchell]

The base that goes into the palm needs to be rounded not an L shape. It will still have the same effect, but for punching would be more comfortable. Thanks and have a nice day.

[LeifBurch]

I just thought of a few ideas to apply to this

[richardhenry]

Nice idea just a bit more than I can afford to put out for a one purpose thing I can get a old type for $10
