"Granate" is German for grenade, and US shops sell it as the Grenade. We read the maker's German pages on November 5, 2026. The company page dates its founding to 1922 and says the cone-bored metal sharpener that Theodor Paul Möbius, brother of one of the two later founders, designed in 1908 laid the foundation of industrial sharpener production. ## What are the Granate's specs? **One hole for pencils up to 8.2 mm, a standard cone, and a blade that is screwed on.** The maker's page gives these fields and nothing on size or weight. | Spec | Value | |---|---| | Maker | Möbius + Ruppert (Erlangen, Germany) | | Item number | 0604 0000 | | Material | Brass | | Holes | One | | Pencil diameter | Up to 8.2 mm (0.32 in) | | Pencil types | Graphite, colored and artist pencils | | Cone | Standard | | Blade | Screwed to the blade bed, replaceable | | Use (maker) | Office and art | | Size and weight | Not stated | | Price band ($$ = $5 to $20) | $$ | ## How does the blade work? **The blade is a steel-colored plate held by one screw, so you can swap it when it dulls.** The maker's Präzision page says every brass sharpener has its blade screwed onto the blade bed for durability, and that matching spare blades come in sets of three or ten. It gives no blade steel or hardness, and we have not tested the cut. ![The Granate taken apart: brass body, a steel blade plate and one screw, drawn by eye](https://stationerytimes.com/images/mobius-ruppert-granate-brass-sharpener-blade-screw.svg?v=7c1b3961) *Body, blade and screw; the maker confirms the screwed, replaceable blade, the proportions are our drawing.

The [best pencil sharpeners](https://stationerytimes.com/guides/best-pencil-sharpeners/) roundup compares more metal and plastic models. ## Who is the Granate for? **It suits people who sharpen pencils by hand at a desk and want a sharpener with a replaceable blade.** For Drawing and sketching, the maker lists artist pencils among its pencil types, up to 8.2 mm across, and gives the use as office and art. - **Drawing and sketching:** artist pencils up to 8.2 mm are listed, with a standard cone rather than the long points of the Pollux and Castor. Skip it for jumbo pencils, which are thicker than the hole. For a rotary desk sharpener see the [Kum Masterpiece](https://stationerytimes.com/guides/kum-masterpiece-sharpener/). ## Where is the Granate made? **Germany, according to the maker.** Its company page says all products with the Möbius + Ruppert label are designed and built 100% at its Erlangen site, and that it buys no components from the Far East. The blade in the maker's product photo is engraved Made in Germany. ## How much does the Granate cost? **Dick Blick listed the single-hole Grenade at US$5.24 on November 5, 2026, in our $$ band ($5 to $20).** Möbius + Ruppert shows no price on its own pages, which lead to dealers. Blick describes it as built for heavy-duty use; that is the retailer's claim, not ours. Hamilton Pens describes it as designed for graphite pencils, where the maker also lists colored pencils, so we note the difference. ## Frequently asked questions ### What size pencil does the Granate take? Pencils up to 8.2 mm in diameter, according to the maker's page. That covers standard hexagonal and round pencils, but not thick jumbo pencils. ### Can you replace the blade? Yes. The maker says the blade is screwed on and replaceable, and that matching spare blades come in sets of three or ten. ### Does it sharpen colored pencils?
