Try one of the Milwaukee Fastback line. My EDC is a Milwaukee Fastback compact. I have $300 folding knives but the Milwaukee is the one I carry every day, lol. $9 at the Depot.I cut up cardboard to pack the recycling and have bought many utility blade holders always looking for something better. I’ve never thought of using a de blade. Not sure they are tough enough for cardboard maybe cutting tape and packing.
Find a Gillette or Autostrop-branded vintage cutter.
