Heiniger Clipper Blade set 31-15

This is the blade set for the 240v, 12v, 7.2v cordless, Progress and Delta 3 clipper.  31-15 refers to the number of teeth on the bottom and top blades (in this case 31 teeth lower blade, 15 teeth upper blade).  The blade number is normally etched into the base of the blade (see picture).

The standard 31-15 blade set cuts hair at around 2mm.
