Grimtooth is a chaotic orcish dagger that has +d2 to hit and adds +d6 damage against all monsters. It is one of several artifact weapons that get in your way of getting Stormbringer from sacrificing. Elven players will never receive Grimtooth as a gift, and it will glow red when there are elves on the level.[1]

As of NetHack 3.6.0, rogues on the Astral Plane have a 25% chance of starting with an orcish dagger[2]. Any player monster's starting weapon has a 50% chance of being an artifact, if there is an artifact with that base item that has not been created yet, so a rogue's starting weapon may be Grimtooth, if it has not been generated already.


While damage bonuses versus all monsters are nice, this weapon is only about as effective as a normal long sword, and therefore is mostly useless. It does, however, average the same damage as a crysknife but without all the attendant bother. It might be useful to wizards who don't want to over-enchant Magicbane, as a +7 Grimtooth will do more damage than a +2 Magicbane, but they would probably be better off using a gifted and unrestricted artifact weapon.

Average damage calculation

The average damage calculations in the following table do not include bonuses from weapon skills, strength, or from using a blessed weapon against undead or demons.

Weapon Damage
+0 Grimtooth \frac{1+3}{2}+\frac{1+6}{2}=\bold{5.5}
+7 Grimtooth \frac{1+3}{2}+\frac{1+6}{2}+7=\bold{12.5}


In UnNetHack, Grimtooth is quite a bit more useful. It is permanently poisoned, so against monsters which are not poison resistant it deals an additional 1d6 damage and has a 10% chance of killing them instantly. Grimtooth is the first gift rogues receive from sacrifice.


This weapon is marginally more effective in SLASH'EM, as it gives a flat +6 damage bonus as opposed to 1d6. Still, there are many better artifacts out there, particularly for the chaotic player. It might be a decent choice for twoweaponing, which is allowed for artifacts in SLASH'EM.
