Wired that I was asked to use clarity, thickness and warmth in the cutter review, but here it is. I gave it a transparency star because it's totally opaque (it's a cutter). As for the thickness, I gave 3 stars as it seems thick enough for a cutter. Awarded three stars for warmth due to the fact that it's a metal part that absorbs the temperature around it when not in use. It's a good cutter, but I'd look elsewhere for clarity, thickness, and warmth.
