What it is

A wire cutter is two handles and a length of taut wire, and it does two jobs extremely well. Held flat against a bat, it releases a leather-hard pot without levering the rim. Drawn down through a block of clay with a guide, it slices slabs of repeatable thickness.

The wire is the working part. Braided stainless wire resists kinking and lasts; plain steel wire cuts more aggressively but snaps under sideways load. Thicker wire (0.4–0.6 mm) cuts a wider kerf, which matters when slicing slabs, because the wire removes material and the slab is slightly thinner than the setting.

For slab work, the technique is to wire the block on a board with two guide strips of known thickness clamped either side. The wire rides the guides and produces a slab of consistent thickness across its whole width — the single most useful trick in hand-building.

How to use it well

  • Lubricate the wire with a little water or slip so it does not drag and distort the pot.
  • To free a pot, hold the wire flat against the bat and pull straight through in one motion.
  • For even slabs, clamp guide strips of the target thickness on either side of the block.
  • Replace kinked wire immediately — a bent wire cuts a wavy slab.

Safety notes

Read before use

This tool carries specific hazards. The notes below are the minimum controls.

  • Wire under tension can snap and whip — wear eye protection when cutting hard or grogged clay.
  • Do not saw back and forth; a single steady pull is safer and gives a cleaner cut.
  • Keep the wire out of children's reach; it is a genuine laceration hazard.
