Here is my absolutely cliched answer! The Trifecta of folding
knives.
Rick Hinderer XM-18 3.5"/XM-24 4" Spanto blade: Crave worthy
knife not just for the apparent ergonomics (from what I read, not
yet owned it), but also for the interesting cross between Tanto and
Spear point blade. Can personalise the G-10 scales some more (got
glow in the dark ones)!
Chris Reeve Sebenza Large: What can I say, this 21 year old
design is the Rolls Royce of pocket folders. Refined and
Sophisticated, I might be reluctant to actually use it for EDC
though. We'll see.
Strider SMF Tiger Stripe blade: 4" of badass blade! The
antithesis of the Sebenza. Use it and abuse it, the Strider can
take it all and ask for more. Old design but proven in military use
since its inception. EDC it and don't be afraid to use it.
