About our Vintage Gear
Slate & Shell
Slate and Clamshell stones are the heart of a traditional set. These materials have a unique, soft feel in the hands. There are 180 bi-convex pieces of each color.
Mexican clamshell stones vary by 'grade.' The traditional grades in Japan are Yuki (snow), Tsuki (Moon), and Jitsuyo (Standard / Utility / Practical).
- Snow-grade is considered the highest quality. The lines of the clamshell are thin and tightly-packed together, covering most of each stone.
- Moon-grade stones are the middle quality. The lines are further apart but still cover a majority of each stone.
- Utility-grade stones are the lowest. They may have some lines or no lines at all. Some players prefer these because they have greater visual variety.
Japanese clamshells stones (from Hyuga they are called Suwabute / Legendary / Phantom) were harvested in Miyazaki until about 20 years ago, when the supply was depleted. Valued for their milky-white color, those slow-growing clams had lines so tightly packed that they were graded on their color instead of their lines. When shining a light through them they will be more orange than Mexican clams, which are more yellow (kind of like the difference between the color of organic eggs and factory-farmed eggs).
The thickness of the stones will affect the price nearly as much as the quality. The most common are size 30 (8.0mm), which is a very comfortable thickness. As you can see, the difference in size is very subtle - again it is a matter of personal preference. Here is a rough overview:
- Size 20 stones are 5mm discs, like nickels. Some prefer this so they lay flat.
- Size 36 stones are 10mm thick, and are what most professionals use.
- Size 50 stones are over 14mm thick, and are nearly round like marbles.
It is common for black stones to be slightly larger than the white ones. This counteracts black's slimming effect - the optical effect of the shiny white stones is that they will appear larger than the matte black when they are actually the same size. Generally black stones will be slightly wider than white, but may also be slightly thicker.
Our stones are purchased second-hand (mostly in Japan) and that is why they are listed here in our Vintage section at prices far below retail. We aim to set our prices at 50% or less of the cost of New items The white stones are cleaned with soap and water, dried, soaked in a 3% h2o2 solution for a week, rinsed with distilled water, then dried again. The are not polished with wax, but our Care Instructions will walk you through how to do that if you prefer that they have a glossy sheen. The black stones are cleaned with soap and water, then rinsed with distilled water and air-dried - if you prefer a glossy look then you can polish them with mineral oil. You may prefer to put a cloth liner at the bottom of each bowl, both to protect the stones from chipping and to protect the wood from the wax or oil.
Please note that these stones are not new - they have been used. Very minor nicks may have been overlooked in our refurbishing process when they do not significantly affect the look and feel of the set. However, seriously chipped stones will be removed and replaced with stones of the equivalent size - if possible we will also match the grade and the patina.
Thank you for helping bring life back to these stones - we are doing our part to re-use a limited resource, with the positive side effect of helping to minimize the global demand for giant clams.
Go Bowls
Go bowls come in a variety of materials. They store the stones during and after the game and provide a unique visual element. Players often keep their captures in an overturned lid.
We recommend choosing a type of wood that appeals to you visually. Also, make sure it is large enough to fit the size of the stones you will use. Bowl sizing is by no means standardized, but for our purposes we use these definitions:
- Small - These bowls will not hold a full set of regulation stones, but may hold enough for a 9x9 board. They are most likely toys from a miniature set.
- Medium - These bowls will hold stones up to Size 25
- Large - These bowls will hold stones up to Size 30
- XL - These bowls will hold stones up to Size 36
- XXL - These bowls will hold oversized stones (above Size 36)
The price of the bowls will depend much more on its material than its size. Certain woods are more rare or coveted than others. But don't worry too much about rarity - choose what looks good to you!
Our bowls are not new. They are purchased second-hand (mostly in Japan) and that is why they are listed here in our Vintage section at prices far below retail. They are visually checked. Those that need refurbishing are cleaned with turpentine before being buffed with our Monkey Wax. If small cracks have started we will address them with glue and include that in the description. Bowls and lids with large cracks are normally discarded (which also means that we end up with some inexpensive mismatched sets if you want to inquire).
Paulownia Boxes
A Paulownia storage box is a beautiful solution for protecting your bowls from the elements. In addition to dust and debris, a good box will keep away humidity and mold.
Vintage boxes are simple - just a basic 4-sided box and a flat lid.
Modern boxes are more robust, with a shallow base. The base has short walls that rise to overlap a large cover. The cover comes down over the top with tall sides. A ribbon often secures the two pieces.
Our boxes are not new. They are purhcased second-hand (mostly in Japan) and that is why they are listed here in our Vintage section at prices far below retail. Both types of boxes are normally built with wooden nails, so repairs involve carpentry skills or wood glue (or both). Because the wood is so light, it is very easily damaged - most commonly, the central divider can become loose and will need to be reset - for this reason it is not recommended for frequent transport.
Floor Boards
A floor board or Goban is a formidable item. They can weigh up to 60 pounds. Each one has its own personality based on its material, color, grain patterns, and thickness. Choosing a board is a matter of preference. For example, some players prefer Pine since it has a very light tone and creates a stark contrast with the stones, while other players avoid bright woods because of the potential glare. Some prefer a thick board while others prefer a thin one that can double as a table board with the legs removed.
One of the primary differences between boards is the portion of the log from which they are cut. Here is a good video on the different sawing techniques.
- Plain-Sawn: These 'Center Cuts' are the easiest way to take slabs off of a tree trunk. This style minimizes the amount of lumber that will be lost, but results in wood that has longer grain on one side than the other, which can lead to warping over time. This cut will present the annual rings as semi-circles in the engrain, while the playing surface of the board will show rippled heartwood. Depending on the tree, the color of the wood may differ between the center and the edges. The sides of the board will have straight lines that run the length of the board, while the top and bottom will have flame-like characteristics. This is a common cut for smaller trees like Pine, Beech, Birch, Katsura, Cedar, etc.
- Quarter-Sawn: These 'Cross Cuts' are taken 90 degrees from the radius of the board. To achieve these cuts, the log must first be quartered, and then sections can be taken. The result is that the annual rings are evenly spaced - this provides higher dimensional stability, as the wood is less likely to warp over time. These cuts will show the annual rings as vertical lines in the endgrain, and those lines will continue across the top and bottom of the goban. In this case the sides of the goban will have the flame-like characteristics. These cuts are more common with larger trees like Kaya, Shin-kaya, Motoyuki, etc.
- Rift-Sawn: These 'Diagonal Cuts' are midway between Plain-Sawn and Quarter-Sawn. Taken between 30 and 60 degrees (ideally 45 degrees), this cut is the preferred style for go boards. The annual rings will be presented as diagonal lines in the endgrain, and this provides the best dimensional stability. In this case, straight lines will appear on most (or all) sides of the goban.
Here is Mr. Kuroki's analysis of various cuts:
The high weight of a Goban means that a substantial amount of the purchase price is to cover shipping from Japan. Seamail shipping of a Goban from Japan to the US or Europe will cost up to $140, or up to $300 for an Airmail service like FedEx, UPS, or DHL. Boards above 15cm thick actually exceed Seamail dimensions, and must be shipped Airmail.
For boards under 15cm, Airmail shipping can still be worth the expense, since it minimizes the amount of time a board spends in transit. This means that there are fewer opportunities for it to become damaged.
Both to minimize the shipping costs and the opportunities for damage, we prefer to store our collection of boards in Japan. We make an effort to keep track of where a board was sourced, so that you can compare your own climate - you may want to review our Care Instructions for tips on minimizing the changes that your board experiences in its new home.
Floor Board Sets
The cheapest option (by far) is to purchase these items as sets, bundled from our warehouse in Japan. This saves us the time and cost of shipping the set to Colorado for refurbishing. Instead, we can ship the set to you directly at a discounted price. Since these sets have not been refurbished, they may need some attention and care. Replacement stones are available upon request.
Accessories
Plenty of other accessories exist for Go. Please let us know if you have any interest in other items and we can try to source them for you. Here are some common ones:
- Wax for treating Boards and Bowls
- Cloth Bags for storing Bowls
- Straps for securing Bowls
- Cloth Covers for Floor Boards
- Legs for Floor Boards
- Stands for holding lids with captures (Komadai)
- Go-themed Art or Antiques
- Fans
- Arm Rests for playing Go for extended periods
