Master surgeons are hard to find, but you are one of the best.
In game terms, this schtick allows you to do thinks nor mindanely possible. You can remove or negate the effect of other Medicine schticks, and several other types of schticks as well. Cyber technology and Arcanotech can be removed by your healing knife, and you can restore patients transformed, possessed, shape-changed or otherwise magically altered. All through mundane means (honest)!
If you perform a full surgery to restore someone who has failed a DeathTest, you are automatically successful, but the patient always requires bed rest and recuperation afterwards.
In case you were wondering, Cyber is designed using Professor.
