I like my kershaw Blur with textured grip and partially serrated blade. they can be found for $50 - $70.

I also like my Big 5 special Gerber Paraframe $20.00. Blade isn't the sharpest, but for futzin around it's a cheap inexpensive knife.

-edit to add-
the best thing i like about the blur, is that i can carry it tip up or tip down.
