Here's a wonderful nexus of framebuilding and Appropriate Tech:
As reported at Afrigadget,
framebuilder-turned-bike-brand-captain Tom Ritchey
sent photos of hand-made tools from bike shops in Rwanda to
WIRED magazine co-founder, Whole Earth Catalog editor, and blogger extraordinaire Kevin Kelly
See the pictures here, via KK's interesting Street Use blog
KK also edits/complies the wonderful Cool Tools blog, a personal favorite. Every day there's a new tool review sent in by a satisfied user. Usually the things are relatively cheap.
