good luck with that knife, and I love knives, even the junky ones!
Again, my main carry piece is the kel-tec 9mm which has proven itself extremely reliable in the 300 rounds I've fired through it, but, as a back up or an extreme conceal situation against a knife for instance, here's what I see happening. Bad guy pulls knife, good guy (me) pulls gun (junkie raven for instance in hypotheticall .25 cal., 6 shot mag with wood handles and a shinny "chrome" finish, hypothetically) bad guy advances, good guy fears for life, fires one or two rounds into bad guy before gun jambs, bad guy, on pcp, meth, cocaine and alcohol, only winces from the loud noise unfased by the bullets (hypothetically a .25 cal) logged, one in his heart the other in his lung. Bad guy keeps right on comming, good guy (me) pistol whips (literally) bad guy into unconsienceness with palm sized junk gun. Situation averted. Later in court, hot shot public defender asigned to scum bag perpatrator, questions good guy (me) as to the reason he had a junkie raven, notorious for street crime and blowing up in the hand of the shooter (documented?) good guy says, "it's all the gun I could afford after taxes, or I thought it was club, or aren't you thinking of Lorcins?"
