In 2004 the editor of "Rock and Ice"; Clyde Soles published a great lil'knot book "The Outdoor Knots Book" with B&W pictures and lots of general and climbing info about ropes and knots.
Not many things are taught today, just like they were 1000's of years ago; using the same 'inventions'; like knots are. Carrying that to the next level; not m/any technologies and science have been tested like knotting / lacing. Man mimicked the weaving of vines, webs etc. to feed, tool, clothe, shelter etc. self and make bracelets, necklaces etc. for'da wife to ornamate herself. Man knotted, even before boiling water. In tooling he compounded the leverage of a stick with the weight and hardness of a rock to make hammer, hitch up useful horse or wind power to work etc. Sheetbends, Squares etc. are 8,000+ years old, and still maid the same!
The knot links on my site are very rich and free; but most miss the history that the books give IMLHO, but in trade some show animations and videos that you can't get from books...
