The Crain No. 974 is a 4 mm replacement blade for the Crain No. 973 Rolling Hand Groover. It fits both the front and rear blade positions on the 973, so a single blade type covers the entire grooving process. The 974 cuts the groove that prepares vinyl seams for heat welding, and is the same blade the No. 973 ships with.
