When I opened the box with my two M390s, I did out of curiosity line up the Spyderholes and compare blade length. They were not the same - maybe 2mm different. I didn't check whether one is "over" or the other is "under" some nominal spec. Until human beings are taken entirely out of the process of finishing and sharpening blades, there are going to be variations...it's unavoidable.
i can't post a pic right now but i'll answer for him.
i have my M4,a mint S30V and XHP milie in my hands right now. M4 and S30V are similar side by side, i've not bothered measuring both took the M4 to compare.
the XHP measures 3 and a hair mm less than the M4 from ricasso just where the hole meets to the tip, measured with a digital caliper. the XHP and m4 are sharpened, i've just raised a burr once on the XHP, the m4 actually has seen much more use/sharpening.
blade height at the ricasso on the M4 is 32mm, barely 30 on the XHP.
anyway i don't see this as a big problem, we're talking about milimeters here, i won't complain about blade life lost, it sounds really unrealistic to expect perfect consistency on production goods, i'll take a properly hand sharpened and honed blade out of the box for some length variations.
