Use the KOH-i-NOOR 4900 sanding block to give a drawing point the shape you need. Rubbing the exposed drawing core against the paper lets you make a fine, rounded or flatter point. It is useful for details, hatching and broad shaded areas.
Contents and design
- 1 sanding block with plywood handle, model 4900.
- 10 layers of sandpaper on one base.
- Overall dimensions: approximately 17.4 × 2.8 × 0.7 cm.
- For shaping the points of dry drawing materials.
When to choose a sanding block
Use the block for graphite, charcoal, pastels and loose drawing leads. It helps you refine an existing point without always making the same round sharpened shape. With a wood-cased pencil, enough drawing core must already be exposed; this block shapes the core.
How to shape the point
Hold the block firmly on a protected surface. Move the point over the sandpaper with light pressure, rotating the lead between strokes for an even point. Keep a consistent angle when making a flat edge. Test the new point on scrap paper before returning to your drawing.
Using a fresh sanding layer
Remove the worn top layer to use the next one. Keep shavings away from your drawing and clear them gently with a soft brush. Store the block dry. Ten layers means one tool with several usable surfaces.
Materials for your next sketch
For thick graphite points, explore Gioconda graphite leads in 4B and 6B. Compare charcoal and graphite for lines and shading.
