I've got a few of Doug's little kits and have added, barely, an oven bag and a few water tabs in each. I've also stuck a SAK Classic in each except for one where I stuck a little L.L. Bean labeled Buck that was a promo freebie with the Buck 110 they have on their site. It seems like a perfect little lock back mini-PSK knife with a much better blade than the Classic but Bean doesn't sell them separately and Buck has nothing like this on their site. It's ChiCom made.

You know the size of the Ritter PSP so what would be the best tiny knife that would fit in the little room leftover in that kit?

I know all about carrying something proper in my pocket, on my belt, etc. I am specifically asking about something that will fit *in* this kit.
