True, setting up effective shots is done by doing just that. Even against an untrained flailing person its going to get bloody (or marked up). A lot of people think they will be able to end a fight unscathed but that is mostly bullshit, imo.
I as well. And my Sensi advised us: “if you confront a knife-fighter you will get cut. If it is just someone with a knife you are in luck.”
Excellent video… thanks for sharing that.
