Magnesium sharpeners

Metal-bodied sharpeners that pair exceptional structural rigidity with full recyclability — engineered for the softest cosmetic formulations.

The material can only be colored to a limited extent.

Our magnesium sharpeners represent the perfect blend of strength, sustainability, and technical excellence. As a material, magnesium offers unique advantages that make it particularly valuable for the cosmetic industry:

Superior Stability & Lightweight

Magnesium is one of the lightest metal construction materials, yet it offers exceptional structural integrity. This ensures that the blade remains perfectly aligned, providing a consistent, high-precision sharpening result every time.

Eco-Friendly & Recyclable

Magnesium is a natural, abundant element and is 100% recyclable. Choosing magnesium sharpeners is a conscious decision for a sustainable production cycle and a reduced environmental footprint.

Precision Engineering for Soft Formulas

The inherent rigidity of the magnesium body minimizes vibrations during sharpening. This is crucial for delicate cosmetic formulations, ensuring a smooth, clean cut without crumbling or breaking the soft lead.

Magnesium is a material story as much as a model family — see how it fits the sustainability range.

One sharpener, many diameters — the Adapter System

To ensure our sharpeners are as versatile as your product range, almost all of our models are available with integrated adapters. These precision-engineered inserts allow for a seamless diameter reduction, enabling a single sharpener to accommodate a variety of pencil sizes found on the market today.

The key advantage of our system is its effortless functionality: the adapter is easily removable, allowing you to switch between different diameters in seconds. This means you always have multiple sizes at hand, providing the perfect fit for various pencil dimensions within one compact tool.

It ensures that whether you are using a slim liner or a thicker pencil, the barrel is always perfectly centered for a precise sharpening result. It is the ideal solution for brands with a diverse portfolio, offering maximum compatibility and convenience for the end user.
