Maybe I missed something, but I thought all US-made Kershaw folders had a stamp with the month and year of manufacture. I got another Skyline today (this makes seven for me) and it has no date. Same Kershaw logo, same model number, everything on the other ones, but no manufacture date. I only ask because I'd like to know the blade steel as it changed to the newer Sandvik in March 2009.
See photos below; mine is exactly like this.
