OK, you've sold me. I already EDC a pocketknife and a Leatherman Core. A knife is too useful a tool to relegate to the multitool so I have little use for yet another knife.

I would prefer that my kids have something as well and current school regulations prohibit anything that is pointy.

Is there something on the market whose size is on the order of a PS4 but does NOT have a knife? I purchased a knifeless FUSE (which is no longer on the market) but it is a bit bigger. My son is OK with it but my daughters would prefer something smaller and cuter.
