Another knife from my weapons collection.

List of used materials:

Metal material for blade and screws can be found here: http://www.blendswap.com/blends/view/69793

Floor material: http://www.blendswap.com/blends/view/67684

And a plastic material: http://www.blendswap.com/blends/view/80440

I've modified plastic material by adding normal map and mixing it with original one in order to get some bumps. Well I haven't got an expected result, but it's my first attempt to build my own material in node editor, i've just started learning anything about all that jazz.

Enjoy, and don't forget to give credits to metarial creators :)
