I don't entirely agree. A knife is so critical a piece of gear that having a spare blade (like on a multi) just makes sense to me. As far as guns are concerned, I never carry more than one unless its a class, practice or competition that calls for more than one, but I imagine combat is a different story.
Just saw a fella leave the range when his AR firing pin broke,supposed to be a very rare occurance.....

I carry some spares for my AR including a firing pin, but so far my rifle hasn't had any of those issues.

I agree that "2-is-1, 1-is-none" falls flat as a truism, and can sometimes overstate things. Really, do you need to have two bandanas to be sure to have one? Now in the case of fire I can see the need for redundancy.

There are probably places or situations where a second firearm would be a high priority. Yet I would rarely have a 2nd one along. Perhaps if I had a chance to go on a once-in-a-lifetime hunt I'd have a spare rifle along. I do have a CCW permit, and I do carry a sidearm concealed where I can, but I never have a BUG. Considering that many police don't carry a second gun, I probably don't need to. I do carry at least one spare magazine, though.

Any gun can break but when I'm carrying an HK I feel my heart is more likely to fail than my sidearm!

I've never liked the phrase, I think this pretty much nails why:

I also find this to be true:

While having a backup blade is fine (and I do!), I've come to the realization that the probability of needing it is extremely low. You have to compound the probability of being in a true survival situation with the probability of either losing or breaking your primary knife (the latter being near impossible with many quality fixed blades now a days). This is the math that is important and, I have a feeling if one was to crunch the numbers, the probability of that backup blade being critical to survival has got to be getting close to lottery winning odds.

So, while I have no issue with having a backup blade, I can't buy into the idea that to not have one is some disastrous failure of planning.

A much better idea. Or carry extras.

The other thing is that chances are if it does break, it still may be at least partially usable.

Is your next thread going to instruct us that the sun doesn't actually rise, but, in fact, the earth rotates?

That's probably a question for Bertrand Russell depending on your point of view! wink

"One is none, two is one"

Yet I never see the instructors who advocate this saying with two backpacks or two sleeping bags...
