Kurogane Kazura Maki-hari Ballpoint Pen Forged Finish

Established in 1911 as Inoue Tool Works, a manufacturer of traditional Higonokami knives, the company’s main products later shifted to construction and civil engineering tools such as chisels and crowbars. Today, it primarily produces attachments for power tools.

“Kurogane Kazura” is a stationery brand created by Inoue Tool Works, utilizing traditional forging techniques honed over decades for knives and swords.

The Maki-hari Ballpoint Pen is made from 1.5mm thick stainless steel using the “Maki-hari” technique, originally employed in the manufacture of matchlock guns. The pen’s design is inspired by matchlock firearms, from the barrel-like shaft to the hexagonal anti-roll feature.

The forged texture preserves the natural look of hand-forged steel. The stainless steel is forged at over 1000°C, producing a surface with a variety of brown and black hues from high-temperature oxidation. Over time, the patina deepens, enhancing its antique charm.

With its solid, substantial metal feel, this pen provides an exceptional writing experience and a sense of ownership. It comes with a genuine leather cap and is housed in a paulownia box, making it perfect for gifting.

Available in two lengths: 13cm and 11cm.

About Kurogane Kazura Forged Products

When stainless steel is hand-forged at over 1000°C, the surface undergoes high-temperature oxidation, producing brown to black tones. With use, natural wear may reveal the original silver color. Over time, the surface will also develop a patina, adding depth and enhancing its antique charm.

About the Product

As each product is handmade, surface variations such as color unevenness, processing marks, and small scratches may occur. Individual differences between items are also possible.

Care Instructions

Stainless steel (SUS304) is not completely rust-proof. Due to the high temperatures used during forging, it is more prone to rust compared to standard silver-colored stainless steel. If rust appears, wipe it off with a cloth. For long-term storage, clean the surface before storing.
