Kum - Glass Bottle Pencil Sharpener

Glass Bottle Pencil Sharpener

Sharpen to a needle-fine point while shavings collect in elegant glass

Pencil shavings collect in clear glass rather than opaque plastic, letting you see exactly when the container needs emptying. The Kum Glass Bottle Sharpener combines German-engineered blades with a weighted glass reservoir that stays put during sharpening. High-carbon steel cutting edges produce consistently fine points without the crumbling or breaking that cheaper mechanisms cause, handling both soft and hard pencil leads with equal precision.

The glass container threads securely onto the metal sharpening mechanism, creating a sealed chamber that contains graphite dust and wood shavings completely. Unlike plastic alternatives that crack or cloud over time, borosilicate glass maintains clarity and structural integrity through years of daily use. The substantial weight provides stability on your work surface, no hand needed to steady it while you sharpen.

This sharpener handles standard diameter pencils and colored pencils equally well, making it practical for studios working across multiple media. Empty the glass chamber when full, rinse clean, and thread it back on. Simple maintenance for a tool designed to last decades rather than months.
