>>337095There are several kinds of slipjoints anon, it's just a vague category that comprises many different kinds of springs, just like locking knives include linerlocks, framelocks, lockbacks, twistlocks...
A Douk Douk has a spring with a square heel, allowing it to have three fixed positions: opened, half-opened and closed. If you give it a VERY solid bump because the spring is so strong, it'll only get stuck halfway. You'd have to purposedly push hard enough so that it would close on your hand. Laguiole type of knives have a round notched heel, essentially a loose lockback mechanism, making them quite easy to close, but leaving the blade loose instead of having it snap back to a closed position, so accidents virtually can't happen.
Swiss Army knives are some of the worst, they mostly have square springs like a Douk Douk, though with a different design, and a spring tht's not as strong, so the risks of accidents are quite high. They often are what most people consider slipjoints to be when they're in fact a bad example. I'll skip on Chinese made knives which WILL cut your fingers for they have so poorly built, the blade is in permanent tension and can close by itself over time.
There are advantages to a slipjoint though: it's internationally legal. Try travelling around the world with a fixed blade or a liner/framelock knife, and see how long you can keep it. Not to mention, a slipjoint will often have a thinner profile than a locking knife, and can thus be concealed very easily, even in areas where knives are quite simply forbidden.
Not everyone is a fagget that hopes to survive a zombie apocalypse with his pocket knife. Some simply use a pocket knife the way it should be used, and a slipjoint is enough. People who use Douk Douks would rather carry a fixed blade knife, but then let's not exagerate things either, you'd have to be a complete retard to have one of those close on your hand.
I suggest you learn how to use a knife.
