Their Top locks are pretty cool, if you get them for less than $50. The steel is rather soft (420J2), but they look classy. Always have good lock-up. I've owned a couple of lock-backs and they are always up to par. Stay away from their "tactical" folders, though. Their Nealy designs are very well executed, and compare nicely to the customs, as far as fit and finish, though materials are a little cheaper. Overall, they are a good company, but as said before, they're not too good at liner-locks. I've returned all of the liner-lock knives I've gotten to the factory, and end up trading the replacements they send.
I intend to eventually get an Optima exchange blade knife, with a few of the different blades, including a ceramic one. The ones I've seen are excellent quality, and look great as well.
