Knife information such as serial number, production date or steel type can be found either on the pocket clip or blade. For reference M390MK or M390 is the blade's steel type.

Some configurations do not have a printed date, serial number, or steel type. This does not affect their warranty or validity.

If further information is needed please take clear well lit photos and upload them to a new ticket within our support portal at: https://support.microtechknives.com/en/support/tickets/new
