Three years out Ive finally sharpened the Stellite 6K blade on my small Model 4--I still carry it every day.
The serrated edge was still cutting just as aggressively, but the straight portion of the blade would no longer pop hairalthough it would still scrape hair, so technically it was still shaving sharp.
I used a diamond rod to true up the edge, then a fine ceramic rod, and finished by stropping on smooth leather charged with CrO. I stropped the whole blade including serrations, pressing them into the leather a bit, and that treatment actually seemed to help the scalloped teeth of the serrations as well. Other than a little coarser finish right above the edge than what Kit put on it originally

, this puppy pops hair like new. The lock still deploys to the same location as shown in the previous two years photos (above), lining up with the left edge of the tang, and whether I nudge the blade open or sling it open hard, the lock-up is rock solid without a hint of wiggle in any direction. In other words I cannot tell any difference in this knife from when it was new, other than my own minor sharpening marks.
I guess Ill hold off another three years before my next review updatethis is starting to sound redundant. Id hate to bore you boys.
