Meet THE STAPLEBREAKER. This morning I got to tour the only commercial wool testing lab in the country. We saw wool being scoured and charred and devoured by caustic solution, and also sliced into tiny bits and studied under massive magnification. And this. Staple samples were fed into this device. Arms would clamp down on either end of the lock and pull and pull and pull until BLAM! It broke. Where the break occurred and how much force was required to make the fibers break (measured in Newtons per KTex) give you a good indicator of the physical strength and health of your wool fibers. #woolgeeksofknitlandia
