Mudtools Shape 4 polymer rib

Mudtools Shape 4 polymer rib with a sharp corner, two straight edges and three curves for throwing, handbuilding, shaping and precisely smoothing clay.

Mudtools Shape 4 Polymer Rib

The Mudtools Shape 4 Polymer Rib is a versatile pottery tool designed for wheel throwing, handbuilding and sculpting. Its distinctive sharp corner creates precise lines in the clay and helps define edges, angles and transitions within a form.

The rib features two straight edges and three curves with different radii. These make it easier to smooth, compress and shape both flat surfaces and the rounded walls of vessels. Thanks to its varied edges, this compact tool can be used at many different stages of the making process.

The rib is made from a unique flexible polymer that resists wear and the formation of burrs. With regular use, its surface gradually becomes burnished, allowing the tool to glide smoothly over the clay while maintaining a pleasant finish.

The Mudtools Shape 4 is available in five levels of flexibility, each identified by a different colour. Softer versions conform easily to curves and delicate walls, while firmer ribs provide greater resistance when compressing clay, removing excess material and creating more defined profiles.

Mudtools Shape 4 Polymer Rib – Key Information

• Ultra Soft - Pink is the most flexible version and is ideal for gently smoothing clay, finishing thin walls and working with soft, rounded forms.
• Very Soft - Red conforms easily to curved surfaces and is well suited to smoothing clay, refining edges and subtly shaping vessels.
• Soft - Yellow is a versatile option for throwing, smoothing and compressing clay, offering a balance between flexibility and control.
• Medium - Green provides greater resistance and is well suited to shaping walls, compressing surfaces and creating more defined profiles.
• Firm - Blue is ideal for stronger compression, precise shaping, removing excess clay and creating crisp, clearly defined lines.
• The sharp corner allows you to create precise lines, define edges and refine details on the clay surface.
• The two straight edges can be used to smooth, compress and level flat or gently curved surfaces.
• The three curves with different radii make it easier to throw and shape bowls, cups and other rounded forms.
• The rib is suitable for wheel throwing, handbuilding and sculpting.
• The tool is made from a flexible polymer that resists wear and the formation of burrs.
• The rib measures approximately 5 × 10.8 cm, allowing it to sit comfortably in the hand and provide precise control over the pressure applied to the clay.
