They're useful if you spend a lot of time outdoors or in almost every blue collar job.

Because they like the utility?

Because it's a useful tool

Because every day im forced to drive an incredibly unsafe machine that has the highest chance of anything i interact with to kill me. A machine so unsafe that in the event of a collision, the safety systems could kill me. My knife has a seatbelt cutter and a glassbreaker, as do every one of my knives. Why would you not carry a knife? Do you carry your keys? Or your wallet? Do you out on clothes every day? You act like its some difficult process to grab my knife when i grab my keys.

I also carry a knife always, use it all the time for boxes and whatnot. Would never consider using it as a weapon for like self defense, that's why I carry the gun at a times.

Knives can come in many varying sizes and form factors, and can be specialized for usage in many practical and commonly encountered situations.

Utility knives take this concept further and often feature multiple additional, opposable heads geared toward other common household uses, such as screw driver heads, bottle openers, nail files, or even little teensy weensy scissors.

Legit question. It's weird to always carry a knife with you. But seems like to be normal for the Lemmy community...interesting.
