Last week my handle for the raising hammer I made in Hungary was CNC milled in birch wood. It had taken quite a lot of time because previously it had been milled in oak. When I spoke to the wood technician he said that the grain of the wood was at an angle and that this would split when used. It brought up a very interesting conversation about the need for craftsmen and traditional crafts skills in the field of modern technologies. Not all items made using modern technologies will work or be better than something handcrafted but that it is the knowledge of both that are needed to apply ideas.
