Drafting Compass Rystor CK-05 — needle and pencil holder, green

Rystor CK-05 is a drafting compass designed for precise circle drawing and technical sketching. It combines a fixed needle point and an adjustable pencil holder to produce accurate radii and reproducible circles. The instrument is finished in green and is intended for use in school, office or drafting environments where controlled measurements and repeatable results are essential.

Advantages

The compass provides a firm needle anchor and a secure pencil clamp to minimise movement while drawing. Its adjustable leg spacing enables a wide range of radii, and the lightweight construction supports extended use without excessive hand fatigue. The simple mechanism allows quick radius adjustment and dependable line consistency for technical drawings, diagrams and geometric constructions.

Suitable for

• School geometry lessons and student exercises
• Office tasks requiring precise circles and measurements
• Technical sketching, drafting and basic engineering drawings
• Art and design work involving compass-based shapes and patterns

Key specifications

• Type: drafting compass with needle point and pencil holder
• Material: lightweight metal and plastic components for balanced handling
• Finish: green
• Adjustability: variable radius via hinged leg and tightening mechanism
• Compatibility: accepts standard graphite pencils or leads trimmed to fit

How to use

Place the needle point firmly at the desired centre on the drawing surface, insert a suitably sharpened pencil into the holder and tighten the clamp to secure it. Adjust the leg angle to set the required radius and retighten the mechanism to prevent slippage. Rotate the compass steadily around the needle point to draw the circle, maintaining consistent pressure and keeping the needle vertical for an even line.

Usage recommendations

For best results, use a well-sharpened HB or B pencil and check the pencil alignment before drawing. Work on a stable, flat surface and avoid excessive force on the needle to prevent damage to thin paper. Regularly check and tighten the pencil clamp and hinge to maintain accuracy.
