Can't go wrong with a multitool or even some short utility knife. Not sure why you'd get strange looks for that. If I'm trying to open a blister package or something and I've got my knife, I sure as hell won't care what the person walking past me is going to think. They'll see a person who's on top of their shit, not desperately clawing their way like a savage into packaging.
Now, if you're looking for a decent knife that's not expensive, you absolutely can't go wrong with a Buck 110. Get if off Amazon and it's $28 USD right now and it comes with a thick leather pouch. Not schway looking but looks great nonetheless and people have been carrying them for a loooong time. I've owned one for over a year now and it's a joy to carry, it has a nice heft to it. It's possible to get one customized like in the image I got off their website but that's more money.
I also have a Leatherman Wingman which was $24 and it has a decent knife. Spring loaded pliers and scissors were the selling point for me. If I were you I'd be looking at something similar. The pliers are a lifesaver for me. I know Home Depot has had some heavily discounted Skeletools recently.
I mean a /cyber/ knife would be great and all but don't short yourself of a handy tool over its looks. I mean shit, even get a small Opinel for $12. But if you really have to have something black/grey, just look for a $30 knife from Kershaw or some other reputable brand. I bought an ugly ass Tac-Force knife for $8 and have been using it for a couple years now for all kinds of shit. Not abusing it but opening a lot of packages, cutting up boxes, rope, etc. Even has a glass breaker on the end that's great for cutting up your hand.

This right here. Self defense is the last thing I buy a knife for. I'm relying on sprinting away.
