love is fleeting, stone tools are forever (or what I learned during reading break)

1. I have a new found respect for cobble choppers. A stone tool which looks totally unimpressive but is, in fact, much more difficult to manufacture. It requires you hold two large rocks in your hand and smash one into the end of the other with great force, while avoiding totally crushing your fingers between the two. Needless to say I was too hesitant to give enough of a blow, and my toolkit is therefore without a cobble chopper.















2. Obsidian is amazing, and ridiculously sharp. Well, I knew that already, but I thought I'd emphasize it again. The leather gloves that I got for my course are covered in cuts (but at least that wasn't my hand). Surgeons can use obsidian blades in surgery, if the patient supplies their own scalpels, because the edge of an obsidian blade is 10 to 20 times sharper than surgical steel, and cuts at the molecular leve;. Wow.









3. Making stone tools is very very fun, and now I want more raw materials to play with. Which is why Harmony and Kristy and I are going to Oregon in April. Yay - obsidian sourcing!

so, like, can I come sourcing? I have a long break between exams and feel the need to get dirty. Also, i have some things I need to cut very finely, if you catch my drift.

molecular level? shit, you should give some sort of warning before you say hings like that! some of us are very stoned while reading this!

'tis true though. that's why cuts from obsidian heal so damned fast. i wish i could find the pictures comparing the edge of obsidian and the edge of a surgical scalpel under an electron-scanning microscope somewhere to post for you guys. it's something...
