## How to Perform the Knee Cut Knee Slice
Here's a detailed breakdown based on expert instruction:
# Knee Cut / Knee Slice
All right, guys, let's learn about the knee cut or the knee slice. Of course,
there is many ways to do this. Let's focus in a basic way, okay? Let's imagine,
lay down here, close guard. Let's imagine I just opened Sab's guard,
okay? And I have to use the knee cutting. Why? If I use the same side knee this
is the same side knee guard pass the knee cut would always be across so I have to
hold his collar I have to push his leg once I push his leg let's move a little
bit this way yes so I'm holding his collar and I'm holding the leg once I push I
have to Faa o trabalho para fazer o corte do dedo.
Este o corte do dedo, ok? O que muito importante aqui?
Eu sempre deveria escutar este gato e eu sempre deveria escutar o dedo dele,
ok? Note como a minha palma est postada por cima do meu dedo.
Ento this way I have a better control, I have better leverage. Very important.
I cannot forget the underhook. This is a very common mistake, especially for the
beginners. They grab the head and then they change base. And here is not good why
because Sab he can escape underneath my
arm. So what's important? Once I'm here,
I'm holding his arm, elbow above my knee. I will get my underhook.
Once I have the underhook, I can keep sliding my knee to change base.
Now I'm waiting on his side. How I'm going to establish side control now. I walk
back a little bit, get on my knees, and then control the side control position okay
so one more time so imagine I just open his guard one hand on his collar the
other hand on his leg I will push his leg down and then I will do the footwork
move this arm here a little bit in order to cut my knee once I cut my knee he's
probably holding someplace I also hold his arm four arm above my thigh so this is
a very important way to to keep him more flat not much to the side get your under
hook and then you can seizure your base rock a little bit to this side and then
establish this side control position okay so that's a basic way to do the knee cut
see you next lesson guys
