I would say to look at Benchmade and Spyderco in that $100 price range. The Spyderco's are really weird looking to me, but mine have good steel (VG-10), are easy to keep sharp, and the weird looking thumbhole works well, so I have learned to like the looks. I like the blade design on several of them, but stay away from the crazy hook-looking things. They look "tactical," whatever that is, but in daily use, they are useless. My $.02.

SOG and Gerber have knives in that range, as does Puma and Boker. I prefer the last two brands over the first two.

As I said in the other thread, I don't care for Kershaw or Buck, never have, personal preference only.

CRKT has great designs, but I haven't been happy with there steel and blade grind. Seems a little too hard to sharpen and keep sharp.

I do recommend liner-locking knives for folders.
