Need?
Arfin, don't follow. Why do you need 5 knives on you at all times???
Well, I didn't say that I
need five (or six) knives at all times, but I suppose some rationale is in order.
Some years ago I set about discovering what knives were available and which would be useful for my family and me to take hiking and camping. I had been out of the game, so to speak, for a couple of decades, and the knives I used when I was young were no longer manufactured.
I tried big knives, like Bowies and fighting knives and found that they didn't do so well for me in general purpose uses. I tried various medium and smaller knives. I found that the quality from certain countries is generally poor, and that the quality from others is generally good.
I joined discussions here at THR, and found that I had overlooked whole classes of knives, so I picked up some of those, too. Of course the whole point of the exercise was to try out different patterns and designs for usability, durability, and so on. In order to do that, I had to start carrying them around.
So I went from carrying a single knife (a Gerber Silver Knight) that I'd used for twenty years, to carrying two or three, sometimes four or more, just so I would have a variety to test as I ran into different tasks suitable for knives.
After a couple of years of doing this, I found certain brands and patterns that worked well for me. I would not declare them to be the best on the market, but within my budget and the time available, the ones I chose were quite satisfactory.
As a consequence of my geek day job, a multi-tool is appropriate gear for me. A small-to-medium "gentleman's" knife is good to have around people who otherwise pay little attention to knives and mostly don't carry one of their own.
I grew to like having a bigger knife that I could use for hacking up a salad for lunch, so one of those became a regular item, too. Although the basic can/bottle opener etc. are also part of the Leatherman, I found that the ones on the SAK are a little more effective, and besides I had extra room in one of my pockets.
And so it goes.
I generally carry one or two that I'm trying out, and another two or three that are just regular gear.
Need?
Not really. Now it's just more of a habit. If I had to strip down to one, I could, but it's really rare that I wouldn't have at least one general purpose knife and the Leatherman. When I'm "going light" it's the Leatherman, a small (under 3") knife, and/or whatever medium knife I have room for.
"Light load" combos have been Leatherman & Leek, Leatherman & Case Pocket Hunter (same size as the Peanut), Leatherman & Stockman, Leatherman & Sod Buster, and so on. When traveling by air, I switch to the "economy" combo, and carry a Gerber Suspension, Kershaw Vapor, and Gerber Mini Paraframe or similar small blade. The reasoning there is that if the luggage goons raid my stuff, it will only cost me $70 or so to replace it all, as opposed to the more usual $250 to buy a new set of the good stuff.
Nah, I don't
need all that hardware, but I've gotten used to having it around.
