The whole issue of "hand-made" or "hand-crafted," presumably in contrast to "machine-made" is a fascinating subject. These distinctions, many of them very artificial, apply to most material objects including guns.

If anyone wishes to pursue the philosophy of this subject, I recommend: The Nature and Aesthetics of Design by David Pye (New York: Van Nostrand Reinhold, 1978) Although the book deals with domestic artifacts Pye formulates a good analysis of "machine-work" vs "hand-work" and the issues that value each.
