Spoken like somebody who hasn't checked the auction house lately for weapons. The abundance of i63 items with > 1000 dps has significantly softened the market for anything else. I have a 1050 dps, 18% atk speed hammer with no other stats that I paid 4.5m for and would not swap for that knife.
The best stat on it is the near-perfect roll for mana regen but I have enough of that on my offhand that I don't need any more for the splinters build that is most common in act 2/3/4 Inferno.
You need upwards of 500 LoH to keep up with Reflect Damage elites. That is the only thing a WD needs significant LoH for, in most builds. (and no, all three splinters don't get the full LoH numbers). I have 150 LoH on an amulet and I get 75 to 225 per burst, judging by the green numbers popping it up. That would appear to be 75 per splinter but I get that variance even if all 3 hit it seems.
The str is throway and the int is a 100 less than is optimal.
It is a good first weapon for somebody hitting Inferno but it isn't something somebody who has been there for a week or more should want. Good luck finding somebody just hitting inferno who a) has more than 5m credits and/or b) is playing an alt and can't afford better/doesn't already have better.
