Just wanted to share a great link to a video of a wonderful old Japanese craftsman cleaving bamboo down to 0.1mm. Having spent many hours sat beside my friend Owen Jones the swill basket maker I am pretty faniliar with this sort of cleaving but not to this fine a finish.
Follow this link to the 8 minute film of him at work. His workshop appears to be in the centre of town and he heats the bamboo over a flame in what looks like a side alley.
Thanks to potter and fellow Japanese craft fan Pat Southwood for this one.
