I remain unconvinced that these are truly hand made. The presence of CNC milling equipment sortof precludes that. Exquisitely made? Beautiful objects that they are? Supreme skill in conjuring them up? Almost certainly.
To be truly handmade, then in my mind, those hands have to guide the materials being worked. In that way, with each step of each item made there will be minute differences each time. If CNC (for instance) is used, then those differences disappear.
There is obviously a great deal of skill in setting up that CNC machinery etc, as there is in producing jigs for routers/bandsaws/etc, so this is not a question of skill.
Using the quote from Carls' website mentioned above, even he admits that it isnt quite handmade, if you read between the lines. In other words, to achieve that degree of precision and finish, you must move beyond 'handmade'.
Anyhoo, thats my tuppence worth......
