This is a safety razor set with 2 brushes. You will need a fur texture for the brushes, just use one of the many found on cg textures. You will also need to use your own HDRI image for the world texture.
I deactivated the hair particle system in the modifier stack for both emitter objects to knock down the file size. You will need to reactivate those as well as the subsurf modifiers.
Wow, saw this going around on twitter this morning, great model. Thanks for sharing it.
