Well, I had no idea as to what it was even with reading you title. To me it looks like planks of wood, so very well done on this shot! I have this a fairly high score in the challenge.
I think it is a great picture, I like the black and white of it, i like your details and sharpness. I really don't think that there is much more you could have done with this shot. Maybe a little more sharpening to get those amazing grooves really to stand out and a tiny crop of the left hand side to get rid of the blown out white on the prong. Bar that it is a brilliant shot well done
At first I thought this might be a toothbrush. Now I think it's a fork. Either way or neither of the two, I think it's a great macro and very abstract. Bumping from 9 to 10.
