STAEDTLER Hexagonal Metal Mechanical Pencil 0.5mm

STAEDTLER Hexagonal Metal Mechanical Pencil 0.5mm

The STAEDTLER Hexagonal Metal Mechanical Pencil represents the pinnacle of contemporary drafting design, combining the timeless comfort of a classic wooden pencil's hexagonal geometry with precision German engineering and Japanese manufacturing. Built with a solid metal shank finished in a tactile matte rubber coating, this drafting pencil offers a reassuring, non-slip grip with gently rounded edges that rest comfortably in your fingers. Its engineered low center of gravity provides exceptional balance, while the 4mm fixed stainless steel sleeve ensures clear line visibility for architectural drafting, technical sketching, and effortless long-form writing.

Key Features

• Ergonomic Hexagonal Geometry: Classic hexagonal profile with softened edges prevents rolling on inclined drafting boards and fits naturally in the hand.
• Tactile Rubber-Coated Metal Shank: Solid metal body coated in durable matte rubber paint provides a smooth, warm touch with slip-free grip control.
• Optimized Low Center of Gravity: Weighted front-forward balance (17.7g) stabilizes each stroke, significantly reducing hand fatigue during extended sessions.
• 4mm Fixed Drafting Sleeve: Extended guide pipe keeps your line of sight clear when drawing against rulers, drafting scales, and set squares.
• Lead Hardness Indicator: Integrated rotating window at the knock mechanism allows quick identification of the loaded graphite grade.

Frequently Asked Questions

What makes the hexagonal barrel design beneficial for writing?
The hexagonal profile mimics the comfortable feel of traditional wooden pencils while preventing accidental rolling on flat surfaces, and its softened edges eliminate finger pressure points.

What type of lead is compatible with this mechanical pencil?
The STAEDTLER Hexagonal uses standard 0.5mm graphite leads across all standard degrees of hardness from 3H to 2B.

Does the rubber paint coating wear off easily?
No, the specialized matte rubberized coating is factory-bonded directly to the metal shank to provide durable, tactile friction that resists peeling and finger oils.

Is the 4mm guide pipe suitable for ruler drawing?
Yes, the 4mm fixed steel sleeve is specifically engineered to sit securely against straightedges and stencils without obstructing line visibility.

How do I adjust the lead hardness indicator window?
Loosen the knock assembly slightly, align the window to your current lead hardness rating, and tighten it securely into position.
