Yes the only difference I've noticed is the sawyer blades has a plastic screw that you use to secure them. But it fits in the same hole with the same diameter and position
They used to have a screw that could damage a cataract shaft if you were using oar rights and the blade hit something that caused the blade to want to spin. The shape of the old screw could crack the shaft. The newer screw is shaped in such a manner that this is very unlikely. At least no more likely than anyone else's blade
Hey, if you want me to take a dump in a box and mark it "guaranteed", I will. I got spare time.
