So last night my DM and I started watching Darker Than Black. About four or five episodes in I turned to her and informed her that I was blatantly stealing those knives for my ninja. She informed me that she would be disappointed if I did not as they are perfect for both the character and myself.
We agreed that they are exotic weapons, are expensive, I will have to roleplay learning how to use them, and I might have to burn some skill points to by the 'skill tricks' to use all the nifty things. They have a decent price so let us make these bad boys awesome.
