i've got two lb 1's, a lb 3, a baby goddard and a newly acquired jester sprint.
both the lb 1's and the goddard are partially serrated, and i like having one of those if i'm just carrying a pe for edc.
i like the jester because it's a little more robust than any of the frn knives.
i don't carry the jester on my keys though. i use a suspension clip that i made to hang it from the top of my left front pocket.
i'm wanting to get a h1 lb hawkbill to add to my small knives.
don't count out the bug slipits either. they're very functional and affordable.
you really can't make a bad choice concerning any of the knives mentioned, it's just a matter of finding one that suits your tastes and budget.
