A clay wire cutter is a length of wire or cable with a handle at each end. You pull it taut and draw it through clay to cut a pot off the wheel, slice a block from the bag or split clay for wedging. For most home potters the best choice is a braided stainless cut-off wire with molded handles, about 15 in long, plus a longer heavy wire if you wedge a lot. Below we compare six clay wire cutters from maker pages and US dealer listings. This is a research-based comparison; we did not cut clay with these tools ourselves.
This guide is about single cut-off wires. Harps and multi-wire frames that slice a block into even slabs are covered in our clay slab cutter guide.

1. Mudtools Standard Green Mudwire: best overall clay wire cutter
The Standard Green Mudwire is the cut-off wire we already name as the best in our best pottery tools guide, and it is the default pick here. Mudtools describes about 15 in of high-grade braided stainless steel cable, sized for a standard 13 in wheel head, between two molded polymer handles. The maker says the cable is stronger than nylon fishing line and resists kinking better than common cable or solid wire.
The handles matter more than they look. With toggle wires, many people wrap the wire around their fingers for grip, which is uncomfortable and can cut skin under tension. Mudtools shapes the handles so you hold them without wrapping. Braided cable also tends to stay straight after being stuffed in a tool bag, so the wire lies flat against the wheel head instead of bowing up into the base of the pot.
Mudtools also sells a Standard Short Orange Mudwire for small pots and cups. Our Mudtools review covers the rest of the brand.
- Length: about 15 in (may vary slightly, per Mudtools)
- Wire: braided high-grade stainless steel cable
- Handles: molded polymer, no finger wrapping needed
- Maker SKU: MT-06-01
Pros
- Sized for a 13 in wheel head
- Kink resistant
- Comfortable handles
Cons
- Wire gauge not published
- Short for big clay blocks
Who should skip it: potters who mostly wedge or slice large blocks; the Heavy Black version is longer and thicker.
2. Mudtools Heavy Black Mudwire: best for wedging and big blocks
The Heavy Black Mudwire is the larger version of the green wire. Mudtools describes a thicker, heavy-gauge braided stainless cable that is stronger and more resistant to kinking, made for big jobs and groggy clay. Dealer Archie Bray Clay adds that it is good for cutting big slabs off a block of clay and for heavier pots and platters.
That makes it the better wire for the cutting part of wedging. In cut-and-slam wedging you slice a block in half over and over, and the extra length reaches across a full block while the thicker cable is the one Mudtools makes for groggy clay. Our how to wedge clay guide explains the methods. Mudtools also lists a Short Heavy Purple Mudwire if you like the thick cable but want a shorter length.
Sources disagree on length. Mudtools says the Heavy Black Mudwire is about 17 in; Archie Bray lists 19.5 in. Neither publishes the cable gauge.
- Length: about 17 in (Mudtools) or 19.5 in (Archie Bray)
- Wire: thicker braided stainless steel cable
- Handles: molded polymer
- Maker SKU: MT-06-03
Pros
- Strong cable for groggy clay
- Longer reach for blocks and platters
- Same comfortable handles
Cons
- Length differs between sources
- Thicker cable leaves a slightly wider cut
Who should skip it: potters who only cut small cups and mugs off the wheel; the standard or short wire is easier to handle.
3. Kemper K35 Wire Clay Cutter: best budget wire clay cutter
The Kemper K35 is the classic toggle wire found in class kits, including Kemper's own PTK Pottery Tool Kit. Kemper describes about 18 in of stainless wire between two 3 in hardwood toggles. Canadian dealer Pottery Supply House lists it as 22 gauge braided stainless steel and says it is for slicing and cutting lump clay and for cutting pots and other wheel-thrown work.
At about 18 in, it is longer than the standard Mudwire, so it reaches across a full clay block for slicing as well as cutting pots off the wheel. The toggles are the trade-off. Hold the wood between your fingers and thumbs rather than wrapping the wire around your fingers, and expect the wood to need drying after each session. Toggle wires also tangle more easily in a tool bag than molded-handle wires.
Kemper also makes the K36, a nylon cord version, for anyone who prefers cord. When we checked Kemper's own store in early October 2026, the K35 showed no stock, but US dealers carried it. Our Kemper pottery tools review covers the full PTK kit.
- Length: about 18 in (45.7 cm)
- Wire: stainless steel; 22 gauge braided per Pottery Supply House
- Handles: 3 in hardwood toggles
- Included in: Kemper PTK kit
Pros
- Very low cost
- Long enough for slicing blocks
- Easy to find
Cons
- Toggles are less comfortable than molded handles
- Wood needs drying
- Tangles in a bag
Who should skip it: anyone who already has the K35 from a kit; upgrade to molded handles instead of buying a second one.
4. Xiem Pro Cutting Wire: best for small work and tidy storage
Xiem's Pro Cutting Wires use a different construction from the others here: 49 very fine stainless steel strands braided in a 7 by 7 pattern, then coated in clear nylon. Dealers say the coating adds flexibility and strength and resists kinking unless the wire is severely bent. The handles are thermoplastic with soft silicone grips, and each wire comes in a clear case so it does not tangle in a tool box.
The line comes in several lengths, which is the main reason to choose it. The Perfect is 11 in, and US dealer Clay-King says it is designed for beginners and for small to medium work. The Excellent is listed at 32 cm by UK dealer Potclays. The Expert is the heavier-duty model for larger work, listed at 19 in (480 mm) by Pottery Crafts and 47.5 cm by Potclays. There is also a wavy Daring version for a decorative cut.
An 11 in wire sounds short, but a cut-off wire only has to span the base of the pot plus room for your hands, not the whole wheel head. For mugs, cups and small bowls it is easier to keep taut than a long wire. We found no US maker page for Xiem, so these figures come from dealers.
- Lengths: Perfect 11 in; Excellent 32 cm; Expert about 19 in; Daring wavy
- Wire: 49-strand 7 x 7 stainless braid, clear nylon coating
- Handles: thermoplastic with soft silicone grips
- Storage: clear case
Pros
- Several lengths
- Kink-resistant coated braid
- Storage case
Cons
- Specs come from dealers only
- Lengths differ between listings
Who should skip it: potters who want one wire for both wedging and wheel work; the Heavy Black Mudwire covers both. See our Xiem pottery tools review for the rest of the range.
5. Dirty Girls Ergonomic Wiggle Wire: best decorative base
A wiggle wire cuts the pot off and leaves a pattern at the same time. The Dirty Girls version uses thin but firm steel wire tightly coiled into a wiggle, held between soft rubber handles that dealers say stay comfortable and easy to grip with wet hands. Pull it through the base of a pot and it leaves a ribbed pattern in the clay.
Dealers list some useful tricks: turn the wheel head slightly while you cut for more varied patterns, leave the textured base on pots that do not need trimming, or use the pattern as a signature mark on the bottom of your work. It comes in 9 in and 14 in lengths, a wide version, and an Ergo Baby 14 in model. The wire gauge is not published.
It works best as a second wire alongside a straight one. A ribbed base is a style choice, and you still want a straight wire for pots you plan to trim and for slicing clay. Our Dirty Girls pottery tools review covers the brand's facet and slab tools too.
- Lengths: 9 in and 14 in; wide version; Ergo Baby 14 in
- Wire: steel, coiled into a wiggle; gauge not published
- Handles: soft rubber, wet-grip
- Effect: ribbed base pattern
Pros
- Decorative cut in one step
- Can skip trimming on some pots
- Good wet grip
Cons
- Gauge not published
- Patterned base does not suit every pot
Who should skip it: potters who want a smooth, flat base straight off the wheel.
6. Mudtools Curly Red Mudwire: best for faceting and texture
The Curly Red Mudwire is a stainless steel coiled wire that ships compressed. You pull it out to the curl you want, up to a total length of about 15 in, so you control how tight or loose the wave is. Mudtools says it works as a cut-off tool and leaves a decorative pattern as you pull it through clay.
The difference from a wiggle wire is that you set the pattern yourself. A loosely stretched coil gives a gentle wave; a tight coil gives a busier ripple. Mudtools also suggests it for faceting, slicing the walls of a thick-walled pot to leave a wavy, cut surface. It says the effect looks good under wood or salt firing and under glazes that break over texture, such as celadon or temmoku. A Curly Short version is also sold.
Like the other Mudwires, it uses molded polymer handles you hold without wrapping the wire. Keep it for decoration, not for slicing clay from the bag, where a straight wire gives a flat face.
- Length: up to about 15 in when stretched
- Wire: coiled stainless steel, adjustable curl
- Handles: molded polymer
- Maker SKU: MT-06-04
Pros
- Adjustable wave
- Faceting and cut-off in one tool
- Comfortable handles
Cons
- Pattern varies with how far you stretch it
- Not for flat cuts
Who should skip it: potters who do not facet or texture their work. A straight wire does everything else.
How to choose a clay wire cutter
Length
The wire must span the widest thing you cut plus room for your hands. Mudtools sizes its 15 in Standard Mudwire for a 13 in wheel head; an 11 in wire is enough for small pots; 17 to 19 in or more suits wide platters and full clay blocks. Measure your largest base or your usual clay block before you buy.
Braided, twisted, coiled or cord
Braided stainless cable (Mudtools, Xiem, and the K35 per one dealer) is strong and resists kinking. Twisted wire is another common type; dealers such as Potclays sell twisted and smooth stainless cutters side by side. Coiled and crimped wires (curly and wiggle) leave patterns. Nylon cord, such as Kemper's K36, is soft and cheap, but Mudtools says its cable is stronger than nylon fishing line.
Handles
Molded or rubber handles let you hold the wire taut without wrapping it around your fingers. Wooden toggles are cheaper and work fine, but they soak up water and tangle more in a bag. If you have small or sore hands, a larger molded handle is worth the small extra cost.
Straight or patterned
Start with a straight wire. Add a wiggle or curly wire later if you like a textured base or faceted walls. A patterned base can replace trimming on some pots, but it is a look, not a shortcut for every form.
Clay slicer jobs off the wheel
A straight wire is also your clay slicer at the bench. Use it to cut a workable piece from a fresh block, slice a wedged lump in half to check for air pockets, and trim the edges of a thick block before you roll it out. A longer, heavier wire is easier for these jobs because the block is wider than a pot base.
Other wire tools
Wire bevel cutters and facet tools hold a wire at a fixed angle for beveled slab edges and faceted walls. They are a different tool from a cut-off wire and suit hand-builders once the basics are covered.
How to cut a pot off the wheel
- Finish the pot and clean slurry off the wheel head around the base with a sponge or wooden tool.
- Hold the wire taut by its handles, flat against the wheel head on the far side of the pot.
- Pull it toward you under the base in one smooth stroke, keeping it pressed down so it does not ride up into the pot. Many potters run the wheel very slowly or stop it for this step.
- Wait a few minutes before lifting, or slide the pot off with dry hands or a pot lifter.
- Throwing on a bat lets you lift the bat with the pot still on it; see our pottery bats guide, and our wheel throwing for beginners guide for the full process.
Care and safety
Rinse wires in a bucket of water after use, let wooden toggles dry, and hang or coil wires loosely so they do not kink. Replace any wire that frays, because broken strands catch in the clay and can nick fingers.
A thin wire under tension can cut skin. Hold the handles rather than wrapping wire around your fingers, and pull the wire through the clay away from your face. Dried clay on wires and handles contains silica: wash it off instead of brushing it dry, wet wipe your table, and wear a NIOSH-approved respirator when you handle dry clay or glaze materials. Our clay dust safety guide covers studio cleanup.
