Since they are the same razor and your SRD razor came with a Free Honing Certificate I'd shoot SRD an email and see if they'd let you use it on the Knife Center razor and BAM you are then sitting with 2 razors honed by SRD allowing you to use one until it is ready to go back in during which time you switch to the other... And so on.

Pretty cool problem to have overall, huh, two brand new razors and now what to do?!
