Words: Jiu Jitsu Style
When we posted this Keenan Cornelius clip back in October 2015, the wrist lock was still the submission nobody in BJJ wanted to admit they respected. It was the move you'd catch a white belt with and then half-apologise for. It was "cheap," it was "for guys who can't pass," it was the thing that got you a stern look from across the mat. Keenan — already one of the most inventive minds in Jiu Jitsu, fresh off building the worm guard and a wall of medals at Atos — sat down and casually rattled off seven of them, smiling the whole way through. The point was obvious to anyone paying attention: the wrist is a joint like any other, and ignoring it is a choice, not a rule.
Eleven years on, that point isn't controversial anymore. It's gospel. So it's worth going back to what Keenan was actually teaching here, because the lessons haven't aged a day.
Watch it: Keenan Cornelius' 7 deadly wrist locks.
Why the wrist lock belongs in your Jiu Jitsu
The whole argument for the wrist lock is leverage versus cost. Your two hands against one of someone's joints is a fight you almost always win, and the motion that finishes it is tiny — a few degrees of rotation or flexion past where the wrist wants to live. That's what makes it "deadly" in the gym sense Keenan meant it: there's barely any warning. A straight armbar telegraphs itself a mile off. A wrist lock arrives in the half-second between your opponent posting a hand and realising he shouldn't have.
The flip side, and the reason every coach drills the tap before the technique, is that the wrist has almost no runway. The margin between "controlled" and "injured" is measured in millimetres, not the long slow arc you get with an arm. Keenan's seven finishes all share the same etiquette: get the control first, apply the pressure slowly, and let your partner tap a beat early. Train them carelessly and you'll run out of training partners. That's not Jiu Jitsu folklore — it's just true.
Seven entries, one idea
What Keenan was really showing in this video wasn't seven unrelated tricks. It was one idea — attack the hand whenever it's offered — dressed in seven outfits. The wrist lock off the failed armbar, when the elbow slips free but the hand is still trapped. The one waiting in closed guard the instant an opponent plants a palm on your chest or your hip to posture. The finish hiding inside your own collar grip when he grabs back. The version that falls out of a sloppy guard pass when his hand hits the mat to base. The one that turns somebody's overhand grip-fight against them. Different doorways, same room.
Once you start seeing the wrist that way, the move stops feeling like a gimmick and starts feeling like a tax you collect on bad hand positioning. Every time an opponent posts, frames, or grips lazily, he's handing you a joint. Keenan's gift in this clip was making that visible — teaching you to notice the offered hand the way a guard passer notices an exposed hip.
From "cheap shot" to championship weapon
The best evidence that Keenan was right is who's finishing with these now. Mikey Musumeci has built half his highlight reel on wrist locks, snapping them on at Who's Number One and ONE Championship against world-class black belts who absolutely know they're coming and still can't stop them. The Ruotolo brothers fold them into scrambles like punctuation. Watch any modern instructional on BJJ Fanatics or any leg-locker's app and you'll find a wrist-lock module sitting right next to the heel hooks — the same "exotic" submission that earned eye-rolls in 2015 now treated as basic literacy.
That's the arc the whole sport has travelled, and Keenan was a decade ahead of it in this video. The wrist lock didn't change. The respect for it did.
So go find a patient partner, drill these seven slowly, and start watching for the hand. It's offered far more often than you'd think — in every guard, every pass, every grip exchange you'll have today. Keenan saw that in 2015. The rest of Jiu Jitsu just took a while to catch up.
See you on the mats.
