I bought a small a few months ago when I was trying to decide if I should spend the cash for a CRK Umfaan.
I'm very impessed with the quality of this knife. The handles have an even finish, the edges have been chamfered. The grooves in the handle are clean and smooth.
The blade is centered well in the handle and the grinds are good, There is on slight uneveness at the very heel of the blade possibly due to the serration machine. ( I got the combo edge blade. )
The lock is solid, no play, I have noticed that the lockup area, that is the interface between the frame and the blade could be larger, but I have no eveidence that it matters.
This is among the sharpest knives I own. The bevel is pulled back pretty far so it's a good slicer.
It's pretty light in weight, and the pocket clip holds well on jeans and thinner slacks. It probably won't accomodate thicker types of clothing. But remember this is a small knife.
The point of the blade pierces very well. The thumb stud was a little sharp on the thumb but a 20 seconds with some very fine sand paper and that was fixed.
Edge holding has been fine, I don't use my knives very heavily though.
I think it's a great knife, there's been a lot of noise about the Camillus EDC, but for the same or less amount you can get the S2.
Psst, don't tell anyone, I don't feel like I need a CRK Umfaan that badly anymore.
