I wonder if SR-77 is done as the flagship of Scrapyard. It seems most of the new blades are SR-101, 154 CM, or INFI. Only the Scrapizashi has been SR-77 lately. Maybe it'll be just for the larger blades and the smaller ones will be SR-101 or 154 CM.
That is what I have been thinking for a while since most new blades have been SR101 and Infi.
