I think a master and an apprentice must both make sacrifices in the modern age. Obviously an apprentice must want to learn and put forth the effort to do so. That means alot of sweating fruitless hours. And the same goes for the smith.
Alot of it has to do with discipline. In the time of apprenticeships things were alot different. The apprentice lived with the smith and worked with him from dawn til dusk. Today we don't have those kinds of arrangements. I think most apprenticeships happen at schools and colleges today.
I teach alot of kids and adults alike, usually just short sessions where they make some small item and are pleased with their results. Once in awhile it catches on and that person starts seeking. Forge, anvil, hammer, tongs, file, grinder, etc.. That is how smithing is moving ahead around me. Slow but sure the traditional arts are preserved and grow. Only because all of us, newbee or old coot alike, put forth our efforts.
I just joined this site tonight and I am very pleased with the discussions here.
