vocabularies

How an electric can opener cuts a can: top-cut (a wheel pierces and cuts the lid around the inside of the top rim, leaving a sharp-edged lid and a sharp can rim) or side-cut / smooth-edge (a wheel cuts through the side seam just below the rim, leaving no sharp edge and a lid that can re-seal the can). A token category recurring across can openers (L11), the primary axis a buyer chooses on; growing (L13).

Answers the question: cut style.
