Lessons of the Swiss army knife
非常好的一个帖子。道出了刀具使用的本质，那些标榜钢材、设计、战术、锁定的现代折刀在普通人90%的使用场景下并不如一把瑞士军刀来得好用。

下面引用帖子中Jackknife网友分享的一段经历：
Over a lifetime, I’ve had several lesions of the SAK. Some just small repairs for convenience, some a bit more important. A few of those lessons come to mind.
We were on vacation in Key West one time, and my son-in-law and I went fishing. far from home, a rented boat and gear, what could go wrong? Yeah.
We get out on the Florida straits, and the little outboard on the stern is running a bit rough. But it gets us out there so we go to fish. We have bait, rods, and some tackle in the rented boat. One of the reels is non functioning due to being gummed up and neglected. I’m a little pissed, but it happens. Soooo, take out the little classic I had mailed to myself where we were staying at the Southernmost Guest House, and go forward. Take out the little Phillips screws and dig out gunk jamming up the little gears. Use the SD tip, and the tweezers to scrape out and a bit of rag with some gasoline on it.
Get the thing cleaned out, take the golf pencil I always carry to take notes on a bit of paper folded up in my wallet, and use the knife blade to scrape off some graphite to use as dry lubricant, seal up the reel and replace the screws and fish. Vacation saved, so we thought. Catch some nice bonefish out on the flats for dinner when we meet up with the girls that evening, and after a few hours start home.
Pull starter and motor grumbles very grudgingly to life. Then quits. Pull again and serval more times, get some seconds of sputtering and then nothing. Key West is 90 miles from Havana, but at this point its a blue line on the horizon. Havana is maybe 86 or 87 miles now. Soooo…
Take off motor cover, use SD tip to take off carburetor housing and find a gunked up carb. Being a pipe smoker, I always have a few pipe cleaners folded in half tucked in my tobacco pouch. Ungunk the fuel intake, and check the gas can/tank sitting in the bottom of the stern. Dirty fuel left over form the Spanish American war. Use classic blade to cut off a corner of bandana to fold over and secure of the fuel intake with fishing line as a makeshift fuel filter. We make our way back toward key West, and by this time I’m in a fine Irish Temper. Give the rental place hell, and I dump some of the gas right out on the cement in front of the office to show the idiot the contaminated gas, and how I used a bandana for a gas filter. Then I give him hell over the fishing reel that I had to work on, while on a fairly expensive vacation, in which I had no plans to end up in Cuban territorial waters. He ends up apologizing and giving us a very deep discount and we accepted. After all, we did come back with some some nice fish for the grill out by the patio.
But…some nice big knife with a blade, no matter what kind of lock, would have been totally useless. Out on the water, some miles from and, we had what was on us. That was it. Yes, a nice sharp blade was needed, but more importably, Phillips driving ability was needed more. Tool as well as knife. Drifting away from land was a sobering experience. If we missed Cuba, the next stop, if we survived that long, was Venezuela or Columbia the other side of the Caribbean.
It was a valuable lesson of having a small tool that is ALWAYS on you. My old man told me that once you go out your front door in the morning, you never know what you will run into before you will make it home again. Carry few things with you that fit into your lifestyle. A sharp little blade is handy, but with the world we live in, some tool capability is needed. A dedicated knife is too useless in general. Most of us are not commandos, SEAL’s, secret squirrels, or jungle guides. We need to open a package, cut a pice of sting, trim a rough nail, pluck a splinter, or dig a burr out from between the dogs paw pads. All of which a large lock blade knife is totally useless for. And for cutting open those packagers, some miracle steel of the month is just not needed. In fact, I like a steel that I can, when needed, strop on the bottom of a coffee mug after breakfast.
I only wish I’d learned all that while I was still young. Could have saved myself a lot of money on the silly knife collecting thing.
