When I started wrestling a single leg grip was taught by my coach as a palm to palm grip with the outside hand on top to avoid someone stripping the grip. BJJ guys call it a gable grip, but I have never heard many wrestlers call it that. I had great coaches with one being a 2x NCAA D1 runner up and olympic alternate. Here is a video of him teaching his navy finish.
That still is a great finish and one that I use all the time, but in Brazilian Jiu-Jitsu I started to have issues with the grip. BJJ and mma doesn't have shoes and a lot of the better Jiu-jitsu and MMA guys would limp their leg out of the single leg. For a highlight of that limp leg technique in action check out the video of Demian Maia vs Tyrone Woodley at 0:32, 1:20, 2:18, 2:25.
And here is a video of Ben Askren showing the technique behind the limp leg.
So how are the best guys in the world holding the single leg these days. Olympic gold medalist Jordan Burroughs showing what I call a guillotine grip because it is the same grip we use all the time on our guillotine choke so BJJ guys are familiar with it. It leaves the palm of the hand open to control the leg and get more control vs the limp leg.
Here is Ben Asken showing the same thing, he was the NCAA champ and undefeated Bellator fighter.
Here is John Smith, olympic gold medalist showing a gable grip in an older video. But more recent videos show him demonstrating the guillotine grip. Which he instructs his athletes to "cover that hand".
