What do you say about using a SAK for self-defense? I know that without a blade lock there is always a risk of serious self-injury. However, as a last resort, could you use a SAK? Since it is legal to carry a SAK almost everywhere it is likely that this is the only blade you are going to carry whenever you may need to defend yourself. What is your opinion, would you use a SAK for SD and if so, what would be the best procedure in order to minimize the risk for self-injury? Any specific SAK which is better for SD?
