I didn't mean to come off like a total smarta$$. I actually think I know what you're referring to. BM can perhaps chime in to clarify, but I recall the liner edges (both ti and stainless) on my AFCK's, CQC7's, and even '99-era 710's and 705's being far rougher than on current liners. My guess was that this may have been the result of switching from waterjet cutting of liners to laser cutting. Either that, or a finishing technique that is involved currently that makes for smoother edges. Now that I think about it, I think even the flats of the liners are now stonewashed as opposed to being satin-finished back in the day.
Are your knives older-production?
Either way, I was never too bothered with the rougher liner edge finishing. If yours are that rough, and they've still got the parts, I'm sure they'll make it right. Sorry that you're having this issue, and to an extent I understand your frustration.
