Wonderful news, I look forward to your findings!Traveled by air this week so had to pick up a package of KCG blades at the local Walgreens and they were MIC with the 5/23 date code. Used them for 6 back to back shaves with my KCG razor and was pleasantly surprised with top notch performace. I'm pretty curious if there is a difference - I have a few tucks of PPI KCG's and will do a blind comparison with multiple blades and report back with the results.
