For those looking for a tool that allows direct contact with the graphite core, the KOH-I-NOOR PROGRESSO 8911-HB is an indispensable choice. Unlike standard wooden pencils, this model is entirely composed of high-quality graphite coated with a protective lacquer.

Technical Summary (Specifications)

• Hardness: HB.
• Length: 153 mm.
• Pencil Diameter: 7.6 mm.
• Graphite Core Diameter: 7.1 mm.
• Packaging: Box of 12 units (pack 12).

1. Woodless Construction and Efficiency

The main distinguishing feature of the PROGRESSO series is the "woodless" technology. This means the entire 7.6 mm diameter of the pencil is used for writing or drawing. This graphite pencil features:

• Maximum Usage: You don't waste wood; when sharpening, you get pure graphite powder that can be used for shading.
• Thick Core: The 7.1 mm graphite layer allows for both fine lines and broad strokes when held at an angle.
• Protective Coating: The lacquered surface ensures your hands stay clean despite the lack of a wooden casing.

2. HB Hardness – The Universal Standard

The HB hardness grade is the midpoint between hard (H) and soft (B) graphite. This makes this sketching tool extremely versatile:

• For Writing: Text remains sharp but easy to erase.
• For Sketching: Perfect for initial outlines and medium-dark shadows.
• Flexibility: The graphite spreads easily on paper, creating smooth transitions.

3. Ergonomics and Durability

Although the pencil is heavier than standard wooden counterparts, this weight provides a sense of stability and control. The 153 mm length is optimal for a comfortable grip, and the high-quality KOH-I-NOOR graphite formula ensures the pencil doesn't crumble and breaks much less frequently than cheap alternatives.

Verdict

The KOH-I-NOOR PROGRESSO 8911-HB is the gold standard for art students, architects, and hobbyists. It is an economical choice (with 12 units per pack) for those who value quality and longevity. The woodless design makes it one of the most efficient tools on the market.

Frequently Asked Questions (FAQ)

Can this pencil be sharpened with a regular sharpener?

Yes, PROGRESSO pencils can be sharpened perfectly with a standard metal or plastic sharpener designed for thicker pencils or universal models.

Does it break easily since it has no wooden body?

While the graphite is solid, it is specially reinforced and lacquered, making it quite resistant to breakage from drops or high pressure compared to simple graphite leads.
