A scalpel is a kind of melee weapon that appears in NetHack. It uses the knife skill, and does d3 damage to both small and large monsters. Scalpels are not suitable for throwing like other knives, and doing so carries a -2 to-hit penalty. They are made of metal.
Scalpels are very poor weapons roughly on par with orcish daggers, with the only real advantage being their inherently erosion-proof material. However, knives tend to be sparse compared to other projectile weapons like daggers, and are slightly worse melee weapons themselves. In any case, the starting scalpel for Healers may be worth keeping as a backup weapon against monsters such as acid blobs that can corrode or rust weapons; you can stash or simply ditch it once you gather a decent stack of knives and/or obtain a primary weapon that is either non-iron or erode-proofed.
The scalpel first appears in NetHack 3.0.0.
A bug caused player monster healers to receive stacks of scalpels during monster generation; this was fixed in NetHack 3.6.2.
In dNetHack, Healers also apply their healing spell skill level to-hit and damage with scalpels (+0 at basic, +2 at skilled, +3 at expert). At max skill, a scalpel is roughly equivalent to other starting weapons in the hands of a Healer, though it is still outperformed by a unicorn horn or quarterstaff at high strength.
