I'm looking for an inexpensive knife that would fit into an Altoids sized PSK. Any suggestions? I found one yesterday (not sure of the brand) but it was $25.99 - more than I'm able to spend - I'm looking to make several of these kits to stash in various bags, pockets, truck etc. I normally EDC several decent knives - but I'd still like to have one in the PSK just. in. case.
