I just designed my Ideal Combat Knife ICS: Critique my design I Included all the various grips because most people really only think about two of them, when all five grips can usually be used on most knives except larger more cumbersome knives, and each grip has particular advantages and uses in a Combat Situation. It's better (IMO) to train to be able to fight with a knife how ever you happen to pick it up, rather than having to worry about changing grips during the fight, and I wanted to design a knife that would be easy to use in any of the five, yet would still call for unique techniques in each position. Let me know what you think! EDIT: BTW there is actually a sixth grip which isnt shown which is the same as grip # 4 except the knife front edge is facing the opposite direction. It takes more training to fight this way as well as with the suicide grip, but again both have there own advantages and disadvantages.
