Scientific Wrestling posted these two great pics. The first pic is of Abraham Lincoln, a wrestler who would have known the double wrist lock by its original name. The second pic is of the famous Masahiko Kimura with the "God of Wrestling," the great Catch Wrestler, Karl Gotch. Kimura learned the Catch wrestling double wrist lock and used the technique to defeat Helio Gracie in Brazil. He is the reason why Brazilian Jiujitsu has such a technique and he is the reason why the double wrist lock is called a Kimura in that system.
