Damagetype not working?

[The Bug]

i'm trying to make so you could only mine materials with a pickaxe (materials actor is inherited from)

here's an example of a weapon i'm trying to make not work with materials:

ACTOR sword : mcweapon replaces fist 7585
{
  Weapon.SlotNumber 1
  Weapon.SelectionOrder 3700
  Weapon.Kickback 0
  Obituary "$OB_MPFIST"
  +WEAPON.MELEEWEAPON
  meleerange 100
  damagetype "unmine"
  +noautofire
  States
  {
  Ready:
    swrd A 1 A_WeaponReady
    Loop
  Deselect:
    swrd A 1 A_Lower
    Loop
  Select:
    swrd A 1 A_Raise
    Loop
  Fire:
    swrd B 5 a_custompunch(19,0,0,"bulletpuff",0,0,0,0,"damage","sword")
    swrd C 5
    swrd D 5
    Goto Ready
  spawn:
    swrp a -1
    stop    
  }
}

Here's the pickaxe:
ACTOR pickaxe : weapon 3462
{
  Weapon.SlotNumber 1
  Weapon.SelectionOrder 3700
  Weapon.Kickback 0
  Obituary "$OB_MPFIST"
  +WEAPON.MELEEWEAPON
  meleerange 100
  +noautofire
  States
  {
  Ready:
    pick A 1 A_WeaponReady
    Loop
  Deselect:
    pick A 1 A_Lower
    Loop
  Select:
    pick A 1 A_Raise
    Loop
  Fire:
    pick B 3 a_custompunch(5,0,0,"bulletpuff",0,0,0,"greenarmor","damage","sword")
    pick Cba 3
    Goto Ready
  spawn:
    pist a -1
    stop
  }
}

here's the materials:
actor materials
{
  Health 100
  Radius 20
  speed 255
  Height 20
  mass 10000000000
  Monster
  +noblood
  damagefactor "unmine",0.1
  +FLOORCLIP
  +friendly
}

and here's the mcweapon class:
actor mcweapon : weapon
{
damagetype "unmine"
}

i don't know what's wrong, but it's not working
help

You're supposed to put DamageType in your projectile or bulletpuff actor definitions.
