I would never deem to argue with the man who feels two firearms to be preferred.
However, my practice is: one firearm, 2 knives, 2 extra mags, and 1 pepper spray.
The knife and pepper spray give me some options the firearm does not provide. You can't use a gun to cut yourself out of a seat belt after a car crash nor to open (most) boxes and letters.
You can't effectively threaten a vicious or aggressive dog with knife or firearm, and I really don't want to harm someone's dog just because he is bad mannered and got out of his yard -- pepper spray supplies another option.
Carrying a second firearm for me, comes in down below carrying two extra mags. My firearm WORKS (or it gets replace/repaired), and I am more likely to need the ammo than a 2nd firearm.
The knife works for self-defense, the knife can be taken more places, and it is more ubiquitously available in the environment (e.g., kitchen, shop, your pocket) than pretty much any other tool or weapon.
(I too have a policy to avoid places with 30.06 signs, including the darn gun shows) but there are some place I can't avoid: Hospitals, the Austin Data Center (State of Texas so go figure, and court (for jury duty.) At Court they are going to make me leave my knife usually, but most places with a 30.06 will allow the knife.)
Learning to USE a knife for defense is NOT very hard -- I practive this and teach actively teach it. Eric mentioned we practice in Austin, plus there are similar groups to ours across Texas, other states and even internationally -- we are not-for-profit so cheap (gym fee we pay is small) and if you want to come try it then please let me know as it is always free the first couple of times.
However, like anything, using a knife without SOME training is not generally as effective as when you have that training.
As Eric said, a
BIG PART of knife defense is ACCESSING UNDER PRESSURE -- if you NEED it you will like need it about 3 seconds ago so be trying to stay alive while under attack AND deploying the knife.
This is big key for those (here) who carry a firearm, with or without a knife or other tool: When you NEED your FIREARM you likely will ALREADY BE UNDER CLOSE ATTACK.
Criminals don't stand across the street and say, "Hey dude, wait right there I have a knife and I am going to come over and rob you."
They find SNEAKY ways to GET CLOSE. The first time you SEE the knife it will likely be against your body -- or already have injured you and maybe be coming in again, fast and hard. (Knife defense is also NOT MUCH LIKE what you see on TV nor what most people practice in the typical McDojo Martial Arts.)
We have learned through FORCE ON FORCE training that to REACH for you firearm while under close attack by a criminal wielding a knife means taking one hand out of the fight and likely you will be seriously injured or killed well before the firearm offers any assistance. (And it does YOU little good to shoot the attacker if you go to the morgue or in for a liver transplant.)
Before you have a firearm problem, you typically have a "Combatives Problem" (and yes, before that you have an AWARENESS and MIND SET issue.)
The best GENERAL strategy has been shown to be: DEAL with the knife (or other serious) attack FIRST, gain time and space (e.g., push off), and THEN DRAW YOUR FIREARM.
You really need TIME AND SPACE to deploy a firearm effectively in most close attack situations.
We have all heard (or practiced) the 21' Tueller Drill
http://en.wikipedia.org/wiki/Tueller_Drill but that is a LONG WAY compared to most knife attacks. Inside your home it is unlikely you will even SEE an intruder at further than 10-12 feet, and outside the home the criminal will likely be within arm's reach before you KNOW his bad intentions (you may suspect and that is good, but few criminals will make it obvious before reaching contact or near contact range.)
We only know ONE WAY to get good at this: Practice.
And
PRACTICE against full speed, fully resistant partners SOME of the time. It' s amazing how many martial arts techniques go to pieces at full speed (even by life long martial artists.)
And sure, someone will say, "Aw, I'll just shoot him." But time and time again we have put on the AirSoft mask and loaded up the Airsoft pistols and then watch the "guy with a gun" get sliced to ribbons. And realize, that is when HE KNEW someone would attack.
Please don't read me wrong -- this is NOT the gun controller's fantasy that "guns don't work" - they do.
FIREARMS are the MOST effective SINGLE way to defend yourself.
However,
knowing how to deploy them UNDER PRESSURE, that is UNDER CLOSE ATTACK, will make you far safer than merely having the firearm.
I am pretty passionate about this issue, and that is the very reason that I formed a group (in Austin) to PRACTICE.
We would love to have any of you join us.
And yes, we scale the force for YOUR readiness and robustness. For those not prepared to go full speed we find the level that is JUST CHALLENGING and build skills. Eventually our goals is for those who continue to practice to reach FULL OUT, but any improvement will increase your odds of staying alive.
Our practice has ONE CLEAR PRIMARY GOAL:
"Go Home Safe!"
