I recorded myself scratching a rock with an oyster shell. This sound was recorded off ten mile creek in hume, ca using a hand held digital recorder and has only been trimmed using audacity. On september 4th 2014.
This is a long sample of me hitting, scratching and rolling all sorts of stones against one another, somewhere in the moroccan desert. The sounds are pretty good quality, recorded with a sony pcm-d50.

Small wind-up toy being wound up and allowed to walk by the mic. The wind-up key is then abused a bit, making a sound not entirely unlike a scratching record (but not much like one, either).
Unidentified animal scratching the floor. Sound made with playing cards. Projet “bruitages” coordonné par josé carrasco, classe de jérôme euphrosine au lycée français de barcelone, hiver 2013.
The sound of a homemade uncoated piezo-contact mic being rubbed against a giant fan. Sounds kind of creepy and weird, and the rubber around the edge of the mic caused it to bounce and make a bouncy kind of sound. Neat! zoom h4n.
