So what else is new? We knew you were a bad boy.I'm a bad boy, what can I say.
Different kinds of wood are used for different kinds of carving. Boxwood is a favorite for those who want to work in a hard wood at a small scale, like netsuke carvers. End grain, it's the trad wood for wood engravings. Walnut, maple, mahogany, ebony and various rosewoods are also used. The trad wood for Japanese woodblock prints was mountain cherry, virtually impossible to get now.
I agree. I do find the pencil lead carvings amazing but what would you do with them. They would be very fragile and to safely display them you would have to put them behind magnifying glass, so why bother.I think when it gets to the point where you need a magnifying glass to appreciate it, you've passed from the realm of art into the realm of techncally astonishing novelty.
