The term "K Cut" gets its name from the obvious letter "K" which is cut out of the center of the round pill.
Note that not all Klonopin have K's cutouts. Only the Roche brand have K cutouts which are more expensive than the generic ones at a pharmacy. Hence why you are unlikely to see any K cuts Versus you everyday genaric brand Klonopin witch out a K cutout.
