Got mine yesterday. Here are my initial impressions:
Blade finish... love it. Stonewash is my favorite for a working EDC. I wish more companies would use it.
Blade/handle ratio... excellent. They fit as much blade as possible into the handle.
Fit & finish... very good. Locks up tight. Grinds are right on.
The knife opens a little "griity" but I suspect it will smoothen out with use. Most people, myself included, have said we prefer a different handle material. I would still like to see a version with g-10. I have been doing some research on Nortyl GTX and it seems to be a very tough polymer. It has been used in race cars. I think it will hold up just fine. I have a 550 griptillian that has seen a lot of use and the handles still look new.
All in all I think the Rittergrip offers a lot of value. It has an almost perfect balance of materials, fit/finish and price. I am glad I got one. It will get a lot of pocket time. It really is "everything you need and nothing you don't".
