Over the years, I have sanded the male joint of two Tokaras and then two Komodo Dragons on at least three occasions each. I've also done it to Carpenters and a couple of Fisherman. I've done it as a matter of necessity because if a rod doesn't fit, I got to make it fit. To date, I've never had a failure from sanding. I'm certainly not recommending you all rush out and do it but I'd suggest that the blanks are not as sensitive to sanding as we are led to believe.
