I bought the exact same razor as my first straight. The only difference been that it did come shave ready from the vendor. When it was ready for a refresh I emails the vendor to see if they taped the spine when it was honed. The reply was surprising and a little disappointing. Apparently all they did was strop it on pasted felt to bring it to shave ready !
I have since reset the bevel and rehoned it. In my mind it now shaves better than when I first got it (that's not to say it didn't shave well before, it did).
If it was me I would send it out for a proper honing, that way you can be 100% sure it is as good as it can be. After that it is up to you weather you hone it yourself in the future but at least you know how it should feel :) I've been making bits of metal sharp for as long as I can remember but without that first honed razor I would never in a million years have understood just how sharp a shave ready razor is and would either have given the game up or struggled on with what I thought were shave ready razors.
Its up to you but it really is worth a few extra dollars to send that bad boy out to a pro. I know you will be itching to get shaving but honestly you will be doing yourself a dis service by not having your first shave with a blade you know for sure is ready for the job.
