The RS-25524-U would be from Tenryu’s Rapid Cut series. Not quite at the level of their Japanese made Gold Medal series, but is a good rip blade. However it’s pretty thin relative to the riving knife.

KDC68’s point about riving knife thickness is valid…the blade’s width (0.079”), plus whatever runout it may have needs to be a tad wider than the riving knife, which I believe is in the 0.09” range. A regular 3/32” thin kerf blade would work fine. The ultra TK will spin a lot easier, but you’ll need a different riving knife that’s less than 0.08”.
