Ive been following this youtube video, about 10 mins into it so far, and seem to be having trouble, when I'm adjusting the value in my multiply function, as the guy does in the video(9:51), I'm not seeing any changes what so ever to the texture of my handle.

Here's how mine looks right now.

This guys looks like this at the same multiply value.

Any tips would be appreciated, bare in mind I've not done any modelling in many years and only just getting used to Blender again, Thanks.
