Marlinespike

Whippings and seizings must be pulled so tight that you can’t do it bare-handed;
the twine will bite you! By tying a Marlinespike Hitch around a proper
marlinespike, screwdriver, ice pick, or similar object, you can exert all the
tension you need.

Electrician’s Tape

Tape works better than cordage for temporarily holding the strands together

while you whip the end. It’s easier to wrap the whipping right up to the edge of
the tape. Masking or painter’s tape will work in a pinch, but neither can be
stretched tight like plastic electrician’s tape.

Cutting Board
You’ll want something to cut the whipped end against. A scrap of plywood or

dimensional lumber will do the job.
