Loop Tool

What it is

A loop tool looks like a trimming tool but behaves differently. Where a trimming tool is braced against a wheel and takes a shaving off a spinning pot, a loop tool is usually held freehand to carve, hollow and texture a stationary or slowly rotating piece.

The loop profile determines the shape of the cut. A round loop hollows a bowl foot or scoops out a solid form. A square or ribbon loop cuts a flat-bottomed channel, which is how fluted and faceted surfaces are made. A large loop removes bulk quickly on a sculptural form; a small one carves fine detail.

Loop tools are also the standard way to hollow a hand-built or pinched form, thin a heavy base, or open up the underside of a thrown piece that was left too thick. Because the cutting edge is a loop rather than a blade, the tool removes clay without digging in and stalling.

How to use it well

• Let the form reach leather-hard before hollowing; soft clay tears rather than cuts.
• Work in overlapping passes from the centre outward when hollowing a base.
• For fluting, mark guide lines with a needle first and follow them with a square loop.
• Keep the loop clean — packed clay drags and leaves a ragged edge.

Safety notes

• Cut away from the body and away from the hand holding the work.
• Hollowing a closed form too far weakens it — leave a consistent wall, do not chase thinness.
• Sweep up carvings before they dry into airborne dust.
