DuskDagger, an underestimated weapon ?

[PDF]

In an Ermor BE game I forged a Duskdagger - mainly because it was early game (turn 15 IIRC), my research was poor and I had only Cons2- to equip my PoD pretender.
And eventually I discovered a very good weapon : stats aren't impressive - dmg 2 att 2- but the weapon is 1 handed and *Armor Negating* ! So you can have 2 of them (4 attacks with Quickness), or one plus a Lucky Coin.
Wielded by a 18+ str SC you can deal enough damage to kill anything in a couple rounds as long as you have a decent attack. As armor is irrelevant you have no problem with thos Ironskinned Cyclops and even less with those pesky IDs
Looking in Zen's MIQR, it appears Duskdagger is the only AN weapon that does add strength, except for the quite unwieldy and expensive Gate Cleaver...
