I carried a BM 943 almost exclusively for about three years. Then I picked up a large left-handed Sebenza 21 and little else has been able to compete with it.
Recently got a blue ZDP-189 Stretch that I've carried for the last few days. It's nice, though I prefer the Sebenza. Still...I probably won't cry too much if I lose a ~$100 knife, but I'd probably cry a lot of I lost a ~$400 knife.
