As of now, we don't have the option listed on the site, but it will be listed as soon as Mark gets another batch in. He's going to send me some outright to "sup-up" and then the option will be listed on the website to just order it that way.
If you're ordering one off of the site brand new and want the upgrade right now, I'm sure Mark would ship the knife directly to me, and I'm sure he could take care of a payment option for you.. if not then I will accept direct payment in that case. I say email Mark and ask him to do the whole transaction, ship me the knife, and I'll charge him later on for the work. Sound good?
