As with many of you, I too have purchased RSK Lg Mk1 (552-1401). I must say RSK design is outstanding. Concept of having improved design (Close to Full Flat, but it is Saber grind) blade on Production Griptilian blade is genius. (Thank you, Doug! 
)
Love the blade shape, 2 notch more jimping on the spine. Needless to say I really like it BKC, Doug Ritter and KW are now offering in M390. I understand that RSK is meant for affordable, yet value added knife. To be able to have EDC with light weight, full flat grind stone washed M390 steel under $200 is nothing short of best value, reliable folder in your hands.
Here comes my constructive criticism.
I am guessing that because of labor complexity and need to keep the cost down, production line must not have too many multiple tasks. Consequently few of the points in fit and finish areas were omitted. In my opinion, I think it can be improve by following simple "do it yourself" tasks.
* Polish:
By completing this, Blade swing is substantially smoother to operate and such, I can tighten up pivot screw enough to have zero blade yaw angle play.
Because the blade was stone washed, I can see some of the points are not as smooth as other counter parts.
I have used 1000 grit paper and then 2000
* Each phosphor bronze washer, both surface.
* Partial liners: Inside where phosphor washer meets
Outside where AXIS lock glides
Also rouge-ed surface of the blade
* pivot face
* Pivot surface (glide against AXIS lock bar)
All surfaces, including AXIS lock bar are cleared with alcohol and then coated with Slip 2000 EWL and heated to adhere coating.
This is before polish. Blade rotation has "hesitation" as AXIS bar rubs against Stone washed surface, in which it acts like grinding stone. (Unless AXIS lock bar is much harder than M390)
After polish.
Here is phosphor bronze washer. Unfortunately my washers were scratched out of the box.
Left is before and right is after running washer in circular motion on 1000 grit paper.
After thought.
I have recently purchased REI edition of 551 (551-1401). It has G10 handle and it has solid feel that is similar to Rift 950, or 810 class.
Here is red line indicates balancing point.
