Having a close look at the Shuriken (of any material), they have a weight of 2 units of material, while them are only made out of 0.5 units (4 sticks makes 4 shurikens). This can be exploited to obtain infinite material, since you can recover for every single shuriken up to 1.5 units of anything, enough for making the mod unbalanced. This is a incredible addon to Gregtech, and i'm suprised for the low amount of downloads that this have. I just let you know that there still people interested in that kind of mods. Great work.

I hope it will be patched.

PD: I highly recommend remove the Links from the mod, and use the GregTech Rings instead. They also have a bug in weight, and NEI doesn't show it´s recipe (If it ever had one).

Fixed with a-50
