If you want REASONABLE sized knives you may actually carry and use -
1) Al Mar Eagle - old school Al Mar, feels great in the hand, classic lines, and slim in the pocket - was also used a lot by diplo cover guys, referred to as the Green Cover Special due to US Passports being green at the time
2 and 3) Chris Reeve Sebenza with a BG 42 blade - a little older than the current - my own experience leads me to the conclusion that BG42 holds an edge better than S30 or whatever the proper designation of the new steel is, plus it is a tougher steel in my experience. Choose the Classic and the Standard profile
4) Spyderco Endura - plain edge, VG10 blade, real clip - best buy in a semi-disposable one-handed opener. Perfect for the pool, the beach, the road, whatever.
5) Benchmade 710HS - the best of the Benchmade Axis locks, high speed tool steel holds an edge forever. I used mine to cut up a house-full of carpet without dulling it past shaving sharp. Good ergos, great lock, and the knife is fun to play with as well as great to use. Run a little emory cloth on the handle in some spots - these tend to come with the odd burr or raised edge on the handle.
SAK's and Buck 110's you can buy as you need them - the Chris Reeve Seb is really the only folder I am carrying these days. Tried others and they just don't do much for me.
You may want to consider swapping out one of the above for a Strider SNG - it is really lightweight, has a great framelock and a great blade profile - they need a lot of dehorning in my opinion, but it would take a bunch of abuse to break one. Look for the Gen 4 or newer, they have larger pivot pins on the knife.
