Itoya 110 Sharp Pencil Review: A Japan-Made Mechanical Pencil Built with Pilot Know-How

Introduction

The Itoya 110 Sharp Pencil is part of a stationery series launched in 2014 to mark the 110th anniversary of Itoya, a long-established Japanese stationery retailer. The series was created with a focus on high-quality functionality, refill performance, and Made in Japan production, and it includes a friction ballpoint pen, an Acro ink ballpoint pen, and this mechanical pencil. What makes the lineup interesting is that these are Itoya original writing instruments built with Pilot’s technology, combining two respected names in Japanese stationery.

This one was priced at 4,620 yen at the time of review, so it sits firmly in the premium hobby tier rather than the everyday pencil market. After spending real writing time with it, here is how it holds up.

First Impressions

The pencil arrives in a simple paper presentation box, clean and understated, with an instruction manual inside. The series offers four color options: a half-matte black, glossy navy, glossy white, and glossy red. The glossy navy version reviewed here has real depth to it, richer than it appears in brighter photography.

From photos alone, the body looked like it might be a resin or plastic build, but in the hand it is a cold, solidly weighted metal barrel with a genuinely premium feel. The barrel is brass, finished with a glossy coating that gives a slight grip against the fingers while still feeling smooth. The body tapers as it approaches the tip, which gives the pencil an elegant silhouette.

The glossy finish deserves a second look. It catches light beautifully and contributes to the overall sense of quality that defines the whole pencil.

Build and Internal Construction

The Itoya 110 Sharp Pencil uses a clip-knock mechanism, so you can advance the lead with the clip in the usual way. It also includes Pilot’s distinctive shake-to-advance mechanism, meaning a firm flick of the pen extends the lead as well. In practice, one confident shake produces just the right amount of lead.

The lead guide is a fixed sleeve with a length of 1.5mm, short enough that the lead should survive most accidental drops without snapping.

Taking the pencil apart reveals thoughtful internals. The lead tank is metal and contains a weight inside, which is what enables the shake mechanism. Care is needed here: held upside down, the lead will slide right out of the tank. Twisting the lead tank releases the chuck, a small metal component split cleanly into three prongs. There is also a moving component inside the body that cannot be removed; it is not the clip, and the top section does not disassemble further without risking damage, so it is best left alone.

The clip itself is metal with ordinary stiffness, and the overall balance sits low, giving the pencil a stable feel in the hand.

Writing Performance

On paper, the writing experience is genuinely pleasant. There is a slight tactile firmness to the stroke, balanced with a respectable degree of smoothness. Because the shake mechanism involves an internal weight, there was a concern that vibration might travel to the tip while writing, but that is not the case in normal use.

Only when writing aggressively hard does a faint clip vibration reach the tip, and even then it is subtle enough that most people will never notice it.

Things to Consider Before Buying

The main drawback is the barrel thickness near the grip. The taper makes the section around the grip noticeably slim. Writers who hold the pencil further back may not mind, but anyone who grips close to the tip will feel the slimness strongly. The overall writing feel invites comparison to the Parker Jotter Core line, though the weight and material quality are entirely different.

The pencil measures 139mm in total length, weighs 28.3g, and has a maximum diameter of 11mm.

Buying Advice

At close to 5,000 yen, this is not a value pick by any stretch. The case for it rests on build quality and attention to detail rather than writing feel alone. The writing experience never rises to a level that is dramatically better than cheaper pencils, but everything about it sits above average, from the brass barrel to the balanced weight distribution. For anyone drawn to beautifully made Japanese writing instruments, it feels worth the price. For shoppers who only care about pure writing performance per yen, there are more economical options.

Conclusion

The Itoya 110 Sharp Pencil is a satisfying, well-made mechanical pencil that blends Itoya’s anniversary heritage with Pilot’s engineering. Its strengths are the pleasant writing feel, balanced low center of gravity, stable strokes, and an overall premium impression. Its main limitation is the slim grip section, which some writers will find too narrow. It is a pencil bought for quality and character, and on those terms it delivers.
