Trimming Tool
A wire or steel loop set in a handle, used to turn a leather-hard pot, cut a foot ring and refine the profile.
Separate a pot from the bat, or slice a block into even slabs.
| Wire diameter | 0.2–0.6 mm |
|---|---|
| Wire length | 20–60 cm |
| Wire material | Braided stainless steel or plain steel |
| Handles | Wooden toggles, dowels, or aluminium grips |
| Kerf loss | 0.5–1 mm per cut |
| Tension | Adjustable on better models |
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.
