A while back, I had the opportunity to work as an interpreter for the biannual (not biennial) 削ろう会(Kezuro-kai) . Now, when you hear planing, I’m sure that you’re first thinking that I said “planning” or something to do with “planes”. The “plane” I mean is the woodworkers tool which has a blade set in a flat surface, and is used to make the surface of an area smooth by shaving very thin layers of wood off it.
Hmm, doesn’t sound exciting does it? But you’d be surprised if you came to this event. I must admit that in the beginning I didn’t know what to expect, and one I was there, I could clearly say that this has been probably the most culturally and historically (in a being in Japan sense) interesting thing I’ve done since I’ve been here in Japan. A competition between carpenters and woodworkers, to see how refined they are with their planes. The main competition is to see how thin and long of a wood shaving you could create. I can’t remember the exact length of the wood, but each wood shaving is on average over 1.5 meters, possibly even 2 meters. And the top level planners can get their wood shaving as thin as 4/1000mm. That’s frick’n thin. So thin that you can pretty much see through’em and the whole thing feels like silk. And if you pull it parallel to the grain, it’s still pretty tough.
It was pretty amazing to see the carpenters at work. I must admit that pretty much everybody was a bloke. There was a small American contingent of students from Palomar College in California whom are studying Japanese carpentry and have come to this event to take part and also observe the architecture along with the actual construction of Japanese carpentry tools. The precision required to create such a thin layer of wood shavings is an art form in itself. The need to maintain a sharp blade, the need to keep it smooth, flat and straight. The physical need be able to pull and give enough pressure to maintain a consistent wood shaving. The various kinds of planes, and techniques used to create traditional Japanese wood work.
