What is the Blackwing One-Step Long Point sharpener?

It’s a small handheld sharpener that cuts a long, curved pencil point in one hole. Blackwing says the body is machined aluminum and the sharpening unit has a German steel blade, and it sells the sharpener in black, grey and white.

It went on sale in late January 2020 at US$20, the price The Pen Addict and The Well-Appointed Desk both quote in June 2020; Blackwing now lists it at US$25. The Well-Appointed Desk describes a matte black body with an off-centre hole, and GetNavi’s Japanese review describes a hexagonal machined-aluminum body joined to a knurled cylinder.

Blackwing publishes no dimensions, so the size comes from Cass Art. Milligram gives 3.1 × 3.1 × 6.8 cm and the Philadelphia Museum of Art store 2.75 × 1.18 in, possibly measured with the box. Blackwing’s official Japanese store sells it for ¥5,280 (about US$33); GetNavi reported a 2020 Japanese launch price of ¥3,400 (about US$22) before tax.

Blackwing One-Step Long Point sharpener to scale: front view about 30 mm (1.2 in) wide and 50 mm (2 in) tall, as Cass Art lists it, with the blade unit above the canister and a 7.5 mm pencil entering, and a top view of the off-centre hole
The One-Step at about 30 × 50 mm, front and top views to scale.

How is it different from a two-step sharpener?

A two-step sharpener cuts the wood and the graphite in separate holes; the One-Step does both at once. The KUM Automatic Long Point, which Blackwing also sells in its own two-step version, stops the first cut with a brake before you finish the graphite in hole 2.

Holes 1 2 (wood, then graphite)
Body Machined aluminum Plastic with flip-top container
Point Long, concave Long, straight cone
Made in China (per retailers) Germany (per retailers)
Price band $$$ ($20–75) $$ ($5–20)

One step is quicker, and there’s no second hole to snap the lead in. The trade-off is less control over how much wood and graphite you expose.

What kind of point does it make?

A long point whose wood curves inward, a concave shape that leaves more graphite exposed. The Well-Appointed Desk said it was the only sharpener it knew, besides the Möbius+Ruppert Pollux, that makes this shape.

Blackwing says the curved point resists breakage. That suits soft pencils such as the Blackwing Matte.

Is the Blackwing One-Step any good?

Reviewers liked the point, but early units varied. The Pen Addict’s first sharpener, reviewed on June 15, 2020, sharpened poorly; Blackwing sent a replacement, which the reviewer said worked as well as expected.

Readers’ comments under The Well-Appointed Desk review are split too, from “the worst pencil sharpener I’ve ever owned” to “it works pretty well”. Blackwing’s FAQ says broken leads usually mean a dull blade, and suggests checking the blade screw’s tightness on a new sharpener.

How do you empty it?

Unscrew the top, lift out the blade unit, and empty the canister below. The Well-Appointed Desk found this simple, and the removable blade unit also makes it easier to clear a jam. Blackwing says the canister holds three fresh sharpenings, so empty it often.

To change the blade, Blackwing says to unscrew it from the sharpening unit, keeping the nut and screw, then fit the new blade and tighten. Its replacement blades come three to a set.

Which pencils fit?

It’s made for Blackwing pencils, which are about 7.5 mm across, like the Blackwing 602; Milligram says it suits pencils under 8 mm in diameter. Blackwing publishes no official list, so jumbo and triangular pencils are unlikely to fit. The Well-Appointed Desk sharpened a Hi-Uni, a Tombow Mono 100, a Mars Lumograph 8B and a Caran d’Ache Supracolor in it.

Where is the Blackwing One-Step made?

Milligram and the MoMA Design Store list it as made in China; Blackwing’s own pages don’t name a country. Milligram adds that it was designed in the USA. “German steel” in listings describes the blade, not where the sharpener is made.

Frequently asked questions

What is the difference between the Blackwing One-Step and Two-Step sharpeners?

The Two-Step (the Blackwing Long Point made with KUM) has two holes: one cuts the wood, the other the graphite. The One-Step cuts both in a single hole, in an aluminium body.

How do you empty the Blackwing One-Step sharpener?

Unscrew the top and lift out the blade unit, then empty the canister underneath, as The Well-Appointed Desk describes. Blackwing says it holds three fresh sharpenings.

What kind of point does the One-Step make?

A long, curved, concave point. The Well-Appointed Desk compared it to the point from the Möbius+Ruppert Pollux, a brass long-point sharpener.

Does the Blackwing One-Step work with other pencils?

Yes, if they are slim enough: Milligram says it suits Blackwing pencils and pencils under 8 mm in diameter. The Well-Appointed Desk sharpened uni, Tombow, Staedtler and Caran d'Ache pencils in it, though it notes the sharpener is meant for graphite.

Why does my Blackwing One-Step sharpen badly?

Defective units have been reported. The Pen Addict's first sharpener performed poorly and Blackwing replaced it; the replacement worked as expected. Blackwing's FAQ blames broken points mostly on dull blades and suggests replacing the blade or adjusting the screw tightness.

How big is the Blackwing One-Step sharpener?

Cass Art lists 3 × 5 × 3 cm (about 1.2 × 2 × 1.2 in). Other shops give 3.1 × 3.1 × 6.8 cm or 2.75 × 1.18 in, and Blackwing publishes no official size or weight.

Where is the Blackwing One-Step sharpener made?

Milligram and the MoMA Design Store list China; Blackwing doesn't say. The blade is German steel.
