Mokumegane Kyuseido Kakari FS
As the first pen ever introduced by Kyuseido, the Kakari draws its inspiration from the brand’s fighting spirit and commitment to design and quality. “Kakari” is the name of a move from the ancient game of Go, usually played in the starting turns as a challenge to the other player. Kakari represents our first move in the stationery world and our indomitable spirit.
Mokumegane is an artisanal Japanese metalworking technique taking several different metals and forging them into a single piece of material. The word Mokumegane (木目金) translates to “Woodgrain/Woodeye” (Mokume - 木目) “Metal” (Gane - 金) and is characterized by its distinct woodgrain pattern formed by the layering of different metals. Traditionally, Mokumegane has been used in ceremonial objects such as sword hilts, vases, and even early types of portable writing instruments called Yatate. Today, Mokumegane is most often used in jewelry, especially wedding bands, in Japan. It is particularly favoured for the unique patina that it can take as each metal will patina at a different rate and into a different color and look.
Our Mokumegane pens use brass, copper, and cupronickel to give a unique woodgrain pattern, and are finished with a machine brushed texture. This material is not something that can simply be melted into a workable piece of metal. Instead, a difficult and arduous solid state diffusion bonding is used to laminate the various different metals together under heat and pressure. Each metal has a different hardness and will wear and patina differently to each other, which will create a unique tactile material through time.
As this is an artisan material, no two pens are identical and will have their own unique expressions and imperfections but all of these pens will evolve with the user to become pieces of art in their own right.
How to use the Pump Piston Filler
The rod in the pen can activated by unscrewing the piston knob of the barrel.
There are 3 spokes (or prongs) machined into the rod, which slide into the hooks of the piston head.
By default, the piston head is locked into the end of the barrel to the piston connector with threads.
When locked, the piston head must be unlocked from the barrel by engaging the spokes/prongs into the hooks of the piston head and turning it counter-clockwise.
Once the piston head is freed from the piston connector, it can be pushed along the barrel with the spokes/prongs engaged in the hooks.
Immerse the nib and feed into the ink and pull the rod to draw ink into the barrel of the pen.
Lock the piston head back into the piston connector by gently pulling the piston knob while turning it clockwise. Take care to NOT overtighten the piston head, as it may get stuck and difficult to unlock on the next use.
Disengage the rod from its hook and return it to its original position.
Warnings
We recommend the use of dye based fountain pen inks ONLY. Use of pigmented inks or iron gall inks may leave visible residue inside the clear barrel that cannot be removed.
Shimmer ink can be used, but the shimmer particles can remain in the barrel or leave visible residue around the o-rings. Similarly,
Self disassembly is not officially encouraged and any damage caused by disassembly is not covered under warranty.
Please place your pens on a pen tray or a pen rest when not in use at a desk. While the materials used in the Kyuseido Kakari and the Kyuseido Kosumi lines are of the highest quality, vertical impact may cause damage to the pen. Repairs are possible but will carry a repair fee.
When writing, be sure to unscrew the piston knob in order to allow ink to flow between the barrel and the feed. Ink flow may be constricted when the piston knob is closed.
Please do NOT attempt to self-repair. Always contact your Authorized Retailer first if you are having issues with your Pump Piston Filler.
