The one that's my favorite is the old Cold Steel Shinobu / Clipmate series. Fortunately, they come in 3 sizes so I can pick the size that best suits my EDC needs for the day. I sometimes carry almost all 6 (2 styles x 3 sizes) but mostly it's just the small clipmate on the keychain and my oldest one, a large clipmate, in the pocket. And yes, I realize it's a bit nuts to have 17 of one knife model when there are only 6 variations.
