Razor blades and x-acto blades are problematical without a handle. Instructor Chris Janowskie jokes they are usefull for slashing your wrists when all the other stuff fails <img src="images/graemlins/shocked.gif" alt="" />. Our "mental template" of a knife includes a handle and this chunk of steel with a point for piercing. Lets examine a razorblade and it's ancestral lithic scrapers, scribers et al. We are looking at a plane scraper ( wood,hide,plant fiber.) Rotate the axis and our razorblade is a cutting tool, sans point. Now, in spite of calling everything older than last weeks cell phone or ISP version "primative", our ancestors didn't fumble around with edged tools lacking handles either. Heres the secret, straight from an archaeological site preserved in a mudflow. First take a small bit of branch. You can use your SAS wire saw or just snap the thing off. Now split it @ halfway. Slip the razor into the split and secure with your dentalfloss, superglue or ductape. You hold it like a toothbrush and make your precision cuts and scrapes. It won't split wood billets. It will make fuzzsticks,process vegetable foodstuffs, mend clothes,butcher small game and help make you presentable for the rescue helicopter ( using the altoid tin signal mirror to shave in <img src="images/graemlins/grin.gif" alt="" /> )
