This mod adds 2 extra damaging steel grenades (1 regular timed grenade, the other a contact grenade). These grenades can be very dangerous to use and cause block damage and destruction (earth -> wood -> stone -> metal, in that order of destructive potential), unlike vanilla grenades. These are not as powerful as TNT.
The new items can be crafted or bought from traders.
The forum topic of the mod is here.
