Please pardon me if this has been discussed. I tried several searches, but came up with a ton of unrelated threads. I'd like to hear from those who have used a knife to protect their gun from someone trying to grab it. Also, would like to hear from those who have drilled for this in training classes. What did you learn from your experiences? How have your blade choices and tactics been impacted & improved upon? Are your experiences applicable for civilian concealed carry ? Thank you -
