I sure hope you get some good responses, 'cos I'm in the same boat.
I keep my EDCs (and a few more!) in a big Gerstner machinist chest. The drawers are just the right size for slippies, tacticals, small flashlights, multitools, SAKs, and other such toys. Not very portable, though.
I keep the rest in those cheap Chinese-made vinyl rolls. The small ones are actually fine for slipjoints, and the large size are OK for smaller folders, but the big tacticals, multitools and bigger SAKs just don't fit the elastic loops. As it is, the loops that are stitched in tear out pretty easily, and the snap buckles on the small ones break if you so much as look at them funny, so I end up buying new rolls every year.
In the last SMKW catalog I saw something that looks better, kinda like the Benchmade and Spyderco knife "wallet" cases. The larger size had 12 individual padded pockets in it, not just elastic loops, and look big enough for even my largest folder. Not too expensive, either, at ~$7 each, and I wouldn't have to worry about my "toys" banging into each other in the case, like they do now.
Lemme poke around on the SMKW site, and see if I can scare up a link...
Ah hah!! Found 'em.
