If your assumption about shards being created by the bond - would that preclude the possibility that now, with a resurgence of Surgebinders, more blades/plates could be created?
The reason I pose this question is this: IIRC there was mention of some 200 or so blades in existence during WoK. Due to the priceless nature of them - they are almost exclusively restricted to privileged seats. Kings, Highprinces, and others of the sort.
But as of the pre-release content, with this new Agent Smith fellow who went after Lift, and just other spine tingle feelings I've had, I am beginning to think there are a lot more shards out there than 200, if that number was wrong - a vast underestimate, or if new ones are being. Grown? Either could be accurate. Plus we know that Parshendi have access to them as well, at least to some extent.
And another question - more than likely somewhat related.
Chances that Dalinar has a Glock-26 strapped to his leg? (By that - I mean a second shardblade. It has been confirmed that it can happen - and IIRC it was stated that he was a highly competent duelist and had won many shards - while he could have given them to friends and whatnot, I find it odd. Especially beings Andolin grants his brother his blade, even if he is the bobby hill of the Kholin family, I would have figured that honorable pops would just give him one if he had a back catalog)
^That may have already been postulated as well, I'm new here still and working diligently on catching up to everything.
