What's your budget ? Some like the Cold Steel pocket Bushman , Kershaw has some very stout offerings , The Zero Tolerance folders from Kershaw are very tuff , and well crafted , in particular the ZT 200 . As regards slipjoint offerings , the old Sodbuster patterns are simple , stout , and slice well . Don't forget the Vic. Farmer , very Bush friendly !Chris
Then get one of these mate...http://www.heinnie.com/Knives/Spyderco/Spyderco-Dragonfly/p-92-191-1668/They really are a superb knife, and certainly one of the best handling knives I ever owned
What bushcraft like tasks are you wanting to do? I only ask as a 3" folder doesn't sound like a typical "bushcraft" ideal to me.
Well you'll be wanting a flat ground knife like the Dragonfly then
