Razor is an incomplete dominant mutation.
Razor is a fairly rare incomplete dominant gene. It is allelic to black pastel and when bred together makes a Black Razor, which is a black snake with a silver stripe down its back. I proved out the super razor this past year (2017) and it is a promising super. The super form is not too overpowering and has lots of room for gene addition. 
The head of a Razor Ball Python is very similar to that of a Normal Ball Python, though with slightly darker tones fading to a light crown with a dot stamp near the neck.
The body of the Razor Ball Python is usually covered in “one-eyed” misshapen “alien heads”, with slight blushing between.
The tail of the Razor Ball Python follows the same patterning as the rest of the body.
