Kemper - Scratch & Dust Tool

Scratch & Dust Tool

Scratch through wet clay and sweep away debris with one dual-ended tool

Sgraffito demands precision, scratching through clay slip or glaze to reveal contrasting color beneath requires a blade that responds to subtle pressure changes without gouging. Kemper's dual-ended tool pairs a flexible steel scratch knife with a fine hair brush, addressing both phases of this decorative technique. The knife end cuts clean lines through leather-hard surfaces while maintaining enough flex to follow curves and contours. Switch to the brush end to clear away debris from your scratched lines, revealing crisp edges without smudging wet slip or disturbing adjacent areas.

This combination proves equally valuable beyond traditional sgraffito. The steel blade excels at refining seams, cleaning excess material from detail work, and scoring surfaces for joins. The brush handles general studio cleanup: removing dust from bisqueware before glazing, clearing trimming debris from wheel-thrown pieces, sweeping loose clay from textured surfaces. Having both tools in one implement means less fumbling for separate brushes mid-process when you need to check your work. The compact design fits comfortably in hand during extended sessions, whether you're scratching intricate patterns or maintaining clean work surfaces throughout your process.
