In our increasingly technological world, finding an all-natural blade that’s sharper than a surgeon’s scalpel seems impossible, yet by shattering volcanic glass, shards are produced that rival the finest industrial-made edges. In addition to this incredible cutting demonstration, the author takes you through the steps in properly dressing a deer including gutting it last, a means of assuring that intestinal contamination does not spoil meat. Although a bit graphic  for anyone who has never field dressed a deer, you’re bound to pick up a tip or two in this brief but informative video. Thanks to Daniel Xu and OutdoorHub for sharing.
