As per my sig-line, I agree with the RatCutlery recommendations. An RC-3 is a great companion. The Izula is lighter but the RC-3 is a better knife.
Other contenders - Falkniven F1 (mentioned before), Bark River (mini CDN, woodland special, highland special, bumble bee, gunny), Mora2000 or Mora #1, Jarvanapa Pukku, Helle, Kellam pukku.
Custom makers - Koyote Knives (he has several smaller, 3/32 fixed blades that are killer), Bryan Breeden CUB, JK-kit knife, Gossman PSK - he now has a little warncliff version that is very cool.
