Razor blade under my tongue while I spit this raw shit
Razor blade under the tongue, like mentioned in represent, is an easy way of concealing a blade, mostly used in prisons. He’s rapping with it, which means he’s never left unprepared.
This line is a double entendre: he’s spitting ‘raw shit,’ so it could also be his wordplay that is the ‘razor blade,’ making him lyrically dangerous.
Nas mentions this image in Represent.
