There are so many great blades to choose from today it could make ya crazy. But thats half the fun. I would go for one of the military type blades. As mentioned already in this post : a trench knife, ka-bar, pilot survival type blade.They fit in your price range. I have carried a M-3 trench knife for 30+ years both in the army and working else where. Its worked for me all over the world. But i'm abit old school and like to keep it simple.
