The New Hotness

  • Book Repair Tape vs. Serrated Cutter: Nope

    An end-of-life roll of parchment paper contributed its serrated cutter bar as raw material for the Gridfinity Tape Dispenser:

    Those teeth look exactly like a tape cutter should look:

    It turns out that book repair tape bounces right off the pointy-but-not-keen edges, to the extent the tape did not cut at all, no matter how hard I tugged at any angle. Perhaps filing one side to make the teeth thinner would improve the results; given the cutter’s provenance it seems like putting lipstick on a pig.

    The original razor blade continues to work fine, so I dropped the serrated cutter into the hollow under the tape roll against future need.

    Book repair tape is tough stuff!
