A pottery needle tool is a sharp steel point set in a handle. On the wheel you use it to cut off a wobbly rim, check how thick the base is, and pop air bubbles; at the table you use it to score joins, cut holes and draw fine lines. For most home potters the Kemper PRO is the best needle tool to start with, because it is cheap, sharp and easy to grip with wet hands. Below we compare seven clay needle tools from maker pages and US dealer listings. This is a research-based comparison: we did not use these tools ourselves.
For a plain explanation of every basic tool, see our pottery tools guide. If you are building a first kit, our best pottery tools roundup lists complete sets.

1. Kemper PRO Needle Tool: best overall
The Kemper PRO is the needle tool you see in most community studios and class kits. Kemper describes a sharp steel needle firmly set in a textured aluminum handle that gives a firm grip for wet hands, and lists it for cutting heavy clay strips, designs and holes. At 6 5/8 in overall, it is long enough to reach into a tall cylinder when you trim the rim.
Its main appeal is cost. Kemper lists it at a few dollars, so it is no great loss when it vanishes into the splash pan, and many potters keep two. The fixed needle cannot be retracted, so cap the point with a cork or store it point down in a tool roll.
- Needle: sharp steel, fixed
- Handle: textured aluminum
- Overall length: 6 5/8 in
- Maker SKU: PRO (loose or packaged)
- Uses (maker): cut clay strips, designs and holes
Pros
- Very low price band
- Textured grip for wet hands
- Long enough for tall pots
Cons
- Needle does not retract
- Round metal handle can roll off a table
Who should skip it: potters who share a space with children or who want a needle they can replace. The DiamondCore Needle Tool covers both.
2. DiamondCore Needle Tool: best retractable needle
DiamondCore's needle tool solves the two complaints about classic needles: an exposed point and a needle that bends and cannot be replaced. Its coated stainless needle slides out of a hardwood handle and locks with a thumb screw, so you can set how much needle shows or tuck it away completely. Replacement needles are sold separately, and DiamondCore publishes a guide to swapping them.
The needle is 1 mm thick, which DiamondCore notes is thinner than many needle tools, and 55 mm (2.1 in) long. The handle is 13.5 cm (5.3 in) and the tool is about 18 cm (7 in) when fully extended. The maker lists it for trimming, etching, cutting and scoring leather-hard clay and wax, slicing rims during throwing, making small holes and signing pots.
- Needle: 1 mm coated stainless, 55 mm (2.1 in), replaceable
- Handle: hardwood, 13.5 cm (5.3 in)
- Overall: about 18 cm (7 in) extended
- Lock: adjustable thumb screw
Pros
- Needle retracts for safe storage
- Adjustable depth
- Replaceable needle
- Fine 1 mm point for signing
Cons
- Several times the price of a Kemper PRO
- Thin needle is less suited to splitting thick, groggy rims
Who should skip it: beginners on a tight budget, or throwers who mostly cut thick stoneware rims. The Xiem XST-15 is cheaper and built for that. More on the brand in our DiamondCore pottery tools review.
3. Xiem XST-15 Stoneware Needle Tool: best for coarse stoneware
Xiem makes two needle tools for two kinds of clay. The XST-15 is the stoneware version: Clay-King lists it for removing a thick, uneven rim of coarse clay on the wheel, with a sharp point plus a broader base that separates and splits the clay away. A thicker shank also resists bending when it meets grog.
The needle is surgical stainless steel and the handle is faceted with an inset rubber grip, so it does not roll off the wheel tray. Overall length is 6.2 in. Colors vary by batch.
- Needle: surgical stainless, sharp point with broader base
- Handle: faceted with inset rubber, anti-roll
- Overall length: 6.2 in
- Maker SKU: XST-15
Pros
- Stiff needle for groggy clay
- Handle will not roll
- Stainless resists rust
Cons
- Thicker point leaves wider marks for fine line work
- Needle is fixed
Who should skip it: porcelain throwers and anyone who signs or draws fine lines. Pick the XST14 instead, which uses the same anti-roll handle with a much finer point.
4. Xiem XST14 Porcelain Needle Tool: best for porcelain
The XST14 is the fine sister of the XST-15. The Ceramic Shop describes a thin, sharp, heat-treated stainless needle made for fine particle clay, for trimming uneven edges on wheel-thrown pieces, making holes and scoring. A thinner needle cuts porcelain without dragging and leaves a cleaner line when you mark or sign a pot.
It uses the same faceted rubber handle as the stoneware version, so it stays put on a wheel tray. Overall length is not published in the listing we checked.
- Needle: thin, heat-treated stainless
- Handle: faceted rubber, anti-roll
- Length: not published in the dealer listing
- Maker SKU: XST14
Pros
- Fine point for porcelain and detail
- Anti-roll grip
- Low price band
Cons
- Thin needle can bend in coarse clay
- Fixed needle
Who should skip it: potters who throw mostly groggy stoneware. The XST-15 is stiffer.
5. Xiem XST04 Needle and Scoring Tool: best needle and scoring combo
Hand-builders score every join, so a needle with a scoring end saves a tool change. Xiem's XST04 has a sharp needle at one end and a scoring tool at the other, hand-forged from one piece of high-grade stainless steel with no glued or assembled parts. A bright rubber grip keeps it from rolling and makes it easy to spot on a messy table.
Chesapeake Ceramics lists it for hand-building, cutting, scoring and clay removal. Length is not published in the dealer listing. Clay-King lists a similar Xiem XST05 described the same way but sold as a fettling and scoring tool; if you order, check the photo matches the ends you want.
- Ends: needle plus scoring tool
- Build: hand-forged stainless, one piece
- Handle: bright rubber grip, anti-roll
- Length: not published
Pros
- Two hand-building tools in one
- One-piece forged build
- Easy to find on the table
Cons
- Costs about twice a single needle
- Scoring end is in the way on the wheel
Who should skip it: throwers who rarely join pieces. A single needle is lighter in the hand. For join technique, see our scoring and slip guide.
6. Mudtools MudShark: best folding needle
The MudShark is a wheel tool with a needle that folds into the body and a fettling knife edge for cutting waste clay from the base of a pot. Mudtools says the needle is sharp and will bite, which is why it folds away when not in use. That makes it a tidy choice for a tool roll or a kitchen-table setup.
Mudtools sells it in six handle colors and does not publish needle gauge, length or materials. If you already own a fettling knife you like, the MudShark's second blade is less of a selling point.
- Tools: folding needle plus fettling edge
- Maker SKU: MT-12-06 (color suffix)
- Needle size and materials: not published by the maker
Pros
- Needle folds away
- Two wheel tools in one
- Bright colors
Cons
- No published needle specs
- Cannot set needle depth like the DiamondCore
Who should skip it: potters who want to measure base thickness with a set needle depth. The DiamondCore locks at any length. Knife details are in our fettling knife guide.
7. Kemper PTK Pottery Tool Kit: best needle tool in a starter kit
If you do not own any tools yet, buying the needle inside a kit is often cheaper than buying it alone plus the rest. Kemper's PTK puts the PRO needle in a vinyl pouch with a loop tool (LT5), ribbon tool, rib, wood modeling tool, sponge, scraper and wire cutter, so you have the full basic set for wheel or hand-building.
Kemper lists the kit at about $38. The tools are basic and you may replace some as you improve, but the PRO needle in it is the same one we pick as best overall.
- Needle: Kemper PRO
- Also in the kit: LT5 loop, 8R2 ribbon, RB2 rib, WT6 wood tool, SPR sponge, S4 scraper, K35 wire cutter
- Case: vinyl pouch
Pros
- Needle plus every basic tool
- Classic class kit
- Pouch included
Cons
- Basic tools you may outgrow
- Pointless if you already own the basics
Who should skip it: anyone who already has a loop, rib and wire. Buy the PRO needle alone.
How to choose a needle tool
Every needle tool pokes and cuts. The choice comes down to needle thickness, whether it retracts, how it grips and how you store it.
Needle thickness and your clay
Coarse, groggy stoneware pushes a thin needle off line and can bend it, so a thicker needle such as the Xiem XST-15 suits it. Smooth porcelain and fine white clay cut cleanly with a thin needle like the Xiem XST14 or the 1 mm DiamondCore. If you throw both, own one of each; they cost little.
Fixed or retractable
Fixed needles (Kemper PRO, Xiem) are cheap and simple, but the point is always exposed. Retractable and folding needles (DiamondCore, MudShark) cost more but store safely and, on the DiamondCore, let you set a fixed depth for checking base thickness.
Grip and anti-roll handles
Your hands will be wet and slippery. Textured metal (Kemper) and rubber grips (Xiem) hold better than smooth wood when covered in slip. Faceted or flat handles also stop the tool from rolling off the wheel tray into the splash pan.
Stainless or plain steel
Stainless needles resist rust if they sit in a wet bucket. Plain steel needles are fine if you rinse and dry them after each session.
Combination tools
Combos save space in a tool roll: needle plus scoring end for hand-builders (XST04), needle plus fettling edge for throwers (MudShark). If you already own the other tool, a single needle is lighter and easier to handle.
What a needle tool does at the wheel and table
Knowing the main jobs helps you pick the right needle.
- Leveling a rim: with the wheel turning slowly, rest your hand on a steady support, push the needle through the wall just below the low point of the rim, then lift the ring of clay off. Our cylinder throwing guide shows where this fits.
- Checking base thickness: with the wheel stopped, push the needle straight down through the floor until it touches the wheelhead, pinch the needle at the clay surface and pull it out. The gap between your fingers and the tip is the thickness. Use pottery calipers for wall and lid measurements.
- Popping air bubbles: prick the bubble at an angle and press the clay flat.
- Scoring joins: scratch crosshatch lines on both surfaces before adding slip.
- Cutting holes and lines: cut small holes, mark templates and sign the base. For drawn decoration through underglaze, see our sgraffito guide.
- Trimming: mark the line where you will trim a foot, then use a loop tool to cut it. See how to trim pottery.
Needle tools are sharp. Keep fixed needles capped or point down, and keep them away from children. When you clean up dry clay scraps, wet wipe or mop instead of dry sweeping, because clay dust contains silica. Wear a NIOSH-approved respirator when you mix dry clay or glaze materials. See our clay dust safety guide.
Push a wine cork onto the tip of a fixed needle tool before you put it in a bag. It protects your fingers and keeps the point from bending.
