The knife fits snugly in the sheath and the sheath sans thumb piece does have good retention. I only removed the thumb piece for pocket carry. I'll replace the thumb piece for neck wear, but I foresee predominantly pocket carry. I find the sheath perfectly fine for pocket carry. I have no feeling whatsoever of a need to order a different sheath just for pocket carry. The wide profile of the standard sheath works quite nicely in my pocket.
I'm most impressed with the quality of this knife. The bevels are even and well formed. The knife was paper cutting sharp but not shaving sharp out of the box. Only a few minutes on the hone took care of that.
The KA-BAR scales are a perfect fit. The only issue I had was accentuated by the fact I'm left-handed. Thus, the bolt protrusions through the nuts of the scale fasteners, although somewhat recessed, were at my fingertips rather than pressed into my palm as they would be were I right-handed and that was a little annoying when gripped. I considered grinding the ends of the bolts so as to be flush with the outside face of the nuts but discarded that idea for several reasons. Instead, and lacking small thin washers to use as shims, I made small plastic washers to incorporate into the bolt/nut handle assembly. Considering the handle contour, I used one of these thin plastic washers under the bolt on the front nut/bolt and one under the nut on the rear nut/bolt. Now the bolts terminate flush with the outside face of the nuts and the depth of the nuts in the handle are the same for both nuts. The depth of the bolts on the palm side is much different between the two, but unnoticed as that side is pressed into the palm of my left hand.
The better scale fastener choice, IMHO, would be round screws that terminate flush with the handle surface on both sides. The screws on either side of the handle would screw into a threaded sleeve between them. Just a thought.
I have dozens of traditional pocket knives of various patterns, steels and cutlery makers. They will now be fighting with this BK11 for pocket/EDC time. I really like this knife.
Yep, I really do like this BK11 knife but as I mentioned in an earlier post in this thread, I also have a BK24 and third party G10 scales on the way. Tracking indicates I should have them Monday. I had also ordered the BK24 factory scales. Next week, we'll see which configuration as well as which knife I favor most.
