In a word .... "Yep!" <img src="/images/graemlins/grin.gif" alt="" />

A lot of people around here would agree with that philosophy. Even Doug, according to what I remember of his articles on this site, (it's been a while since I last read through them) has a scalpel blade in his smallest kit for a backup to his EDC which in itself includes both a large folder and multitool as well. That's three blades.

I personally don't go much for big knives. If I need more than a 5" blade then I must be in some serious #$%^ like waking up in a south american rain forest. <img src="/images/graemlins/tongue.gif" alt="" /> With a 5" blade I can split logs up to 4.5" diameter... maybe even 4.75" if I'm careful. My current outdoors EDC is a 4.5" fixed blade (BM10505DPT) although I just put an order in tonight for an upgrade (BM190DPH) to that knife which will actually be taking me down to 4.0" for my one and only outdoors EDC blade.
