Premium sandblast alert! The Brebbia "2765" Acorn might just be my favorite shape from the Italian firm. It is a comfortable and well-executed shape; both delicate and natural. This particular example boasts some seriously impressive grain that begins directly underneath the bowl and blooms upwards, coating all sides in finely etched rings. Add to that the lightness of the piece, and the superb hand-feel, and I will bet my bottom dollar that you'll reach for this pipe regularly.
