This type of strike becomes much more important when your looking at self defence and being able to stun or stop an attacker quickly that could be much bigger than you,so you can safely escape,this type of punch is also not seen in MMA ,one of the main reasons is modern Boxing gloves dont allow you to land with the part of the knuckle that gives you this sort of power MMA gloves and bare knuckle do and thats what I teach
