In 1994, my better half came home from work with a little red knife. It was a Chinese clone of a Vic classic that her boss had bought form some ad agency with their corporate logo on it. It was a horrible POS. I went out and bought a real classic and gave to Karen so she could see the real quality difference. She took it to work and showed the boss, who promptly sent all the clone back and ordered real SAK classics.
For the next few months, I watched Karen abuse and torture the little knife, and it not only held up, but kept on keeping on. It made a believer out of me. I had always respected little pocket knives, having watched my dad get by in life with his little Case peanut. So I put a classic on my keys and for the next 20 some years, used the ever loving dog poo out of the the thing.
In modern life in America, and most places in the 21st century, you really don't need that much knife. Last summer I started to carry a Victorinox executive. It had been a long time coming, but I LOVE the 74mm SAK. Unlike the 58mm, the 74mm has a blade just enough longer that it can slice a thick sandwich in half, cut a slice of pie, or carve up some nice BBQ ribs. And it has, for a very small amount of size increase, greater tool capacity than my old classic. The SD tip of the orange peeler works well on the sight adjustment screws of most gun sights. The spear shaped end of the nail file works well on very small Phillips screws like in electrical devises. The scissors are handy as heck on many things, and have greater reach than the 58's. With two knife blades it gives the same choice of having different blade edges like on a two blade jackknife or penknife. And the serrated blade on the orange peeler makes short work of zip ties. To put the gravy on the potatoes, the 74mm still fits down in the coin pocket of the jeans leaving room in the main pockets for other needed items.
I LOVE the 74mm executive! For a retired old machinist now living in Texas and doing a lot of fishing, its a great EDC pocket companion. It's more than big enough to cut what needs to cut, yet small enough to forget about until it's needed. I use the executive to open all kinds of packages, break down the box for the recycle bin, cut rope/twine/string for the garden, deal with loose screws both flat and Phillips, trim beard/mustache hairs, and even trim fingernails with it. The blades are enough to cut plastic sheeting for painting drop cloths, and open bags of mulch.
Like my old man told me on many occasions; 'It doesn't have to be big, just sharp.'
