|Examples of Sterling Silver Zanshins|
The omeyama yoneyama shown is my own embellishment of the classic yoneyama shape (top left). The classic yoneyama shape that we are all familiar with has a very playful and active energetic to it. I believe this is due to the highly dichotomous nature of the tool; a large "yang" blade combined with a small sharp point. This makes the tool very top-heavy and urges it to oscillate when being used for point stimulation. The length of this tool is fairly short (less than 2") which lessens the imbalance of mass caused by these two opposing ends. This short length also makes the tool feel "handier," fitting in the fingertips and being used for quick and active stroking along the meridian with the blade or scattering with the point. The elongated yoneyama shown is my own variation of the classic shape and makes an excellent pediatric tool. The extra length allows the pointed end to have a more stable feel for point stimulation while the blade can still be used for invigorating qi and blood on the surface. The blade of both of these tools is very angular/sharp/yang and is quite invigorating/dispersing compared to the the yin nature of an enshin ball.
The tool that we generally think of as a "zanshin" is a long cone made by folding a pie shaped section of metal into a cone shape. This creates a pointed end and a hollow and curved bladed end. The bladed end can be used for point stimulation as well as being used for "pocking" the surface. This pocking is accomplished by lightly tapping the hollow end so that it lands on the skin in a parallel plane so that a suction cup popping sound is made. This is another method of invigorating qi and blood flow. The zanshin shown is a variation of the classic folded tool described above, except that it is made of solid silver round bar that is forged into a point and hollowed on the other end. I prefer making them this way and like the added mass obtained. The tool is also smaller in diameter than the folded form, which gives both ends a much more precise feel. The pocking effect is similar, although I would say it is slightly stronger (more dispersive) with the smaller hollow. The reason I believe this to be true is simple physics. The smaller hollow has a smaller surface area contacting the skin so the force is divided across that area. For this reason, the smaller hollow end should be used in a more gentle way than its bigger brother. The zanshin traditionally had a pointed end, but this version can be made with a ball end if you prefer (as shown).
