You didn't specify your intended use/setting, but generally speaking, I agree with MJ (that's not to say I don't have some of the fine knives others mentioned above; mostly for various kits). One of my favorite and most-used small fixed-blades is the A.G. Russell Woodswalker. Not "beefy" by any stretch, but useful. 6" OAL. 2.375" blade. Light. Choice of Kydex or leather pocket-pouch sheath. <$30. And for me, one of its best features for a small fixed-blade, the handle is generous enough that it makes the knife useable. Went with Kydex; didn't care for the "flap" on pocket sheath (many folks slice off the flap). Good value for the $$$.
