Ručné strúhadlo na ceruzky Staedtler 510 20 metalické kovové

Metal double-hole sharpener — Staedtler 510 20 Metallic Metal is a manual pencil sharpener made from durable metal with a metallic finish. It provides precise sharpening for standard pencils and has two sharpening holes: one for standard-sized graphite pencils up to 8.2 mm diameter with a 23° sharpening angle for clear, accurate lines, and one for thicker graphite and coloured pencils up to 10.2 mm diameter with a 30° sharpening angle for broader, softer lines.

Advantages

The metal construction ensures long-term durability and stable sharpening. Two separate holes with different angles allow controlled sharpening results depending on the pencil type and desired line quality. The compact design is simple to use and easy to maintain.

Suitable for

• Standard graphite pencils (≤ 8.2 mm) for writing and precise drawing
• Thicker graphite and coloured pencils (≤ 10.2 mm) for sketching and colouring

How to use

Insert the pencil into the appropriate hole according to its diameter. Rotate the pencil or the sharpener gently to remove wood and expose the core until the desired point is achieved. For finer, accurate lines use the 23° hole for standard pencils; for softer, broader strokes use the 30° hole for thicker or coloured pencils. Empty shavings and clean the sharpener regularly to maintain performance.

Recommendations

Use the 23° hole for standard writing and detailed drawing, and the 30° hole for colouring and sketching with thicker leads. Avoid excessive force to prevent breakage of pencil leads and to prolong blade life; replace or sharpen blades as needed according to wear.
