I only need one more trophy in this game to get the platinum trophy. 
Alls I need to do is hold a "sharp" weapon I believe it was (weapon made from Pure Bladestone) 
If someone would like to just let me hold the weapon in the game so I can get the trophy it would be greatly appreciated...  
If not, it's cool, figured I'd ask at least lol 
the pure bladestone refuses to drop for my friend and I, no matter how many hours we tried =/ 

Dude... me too. I have played this game into the dirt. Done everything there is to be done. But that god damn Bladestone. There's no boss that drops it and there's no easy enemy that drops it. It sucks. If you didn't already know this, the best way to get it is to get pure black world tendency in the Shrine of Storms, then spam the Black Phantom Dual-Katana Skeletons. I did this for awhile, but to no avail. I just gave up.

Yeah that's what my friend and I tried on our own games and still no luck.
