Does Spyderco stamp the name of the steel that the blade is made of on the blade? I ask this because I understand VG10 is replacing ATS-55 on the Merlin. I am going to order one on line and want to be sure I get the VG10 version rather than the old ATS-55. If not, how does one determine the type of steel that is used or determine that they are getting the latest version of a particular Spyderco knife? Thanks a lot for the time and attention you spend on this thread.
