Just some of the folding knives I've collected over the years:
Top: CRKT SRT High Risk environment
Left: 2 Spidercos, a Delica and a Credit Card (not very useful but cool)
Right: 2 Gerber EZ-Outs, Big one is a 3" blade, 3 1/2" overall
Center: Frontier Double Eagle (thought it was an Old Timer but I was wrong). Broke the tip of the locking blade somewhere along the line, and ground it to compensate. Skinning blade doesn't lock.
The SRT is the meanest looking folding blade I own.
My EDC is a tiny Leatherman Squirt Ps4, not even 2" long, 3/4" wide, 3/8" thick. Since it's not a for self-defense it's very handy. Blade, file, scissors, 2 screw drivers, and a tiny but surprisingly tough and useful pliers.
Another GREAT EDC (if not for SD) is any folding razor knife. You can change blades, and it does everything a Stanley knife does, but it no bigger than any of the bigger ones in the picture. And if it breaks? (Which they hardly ever do) they are cheap to replace. The Depot sometimes sells them in packs of 3 and occasionally there's a smaller one with a down-sized replaceable blade.
