You guys don't wear bike helmets in the woods? I do, I fashioned a face shield from my cars grill that fell out one day going down the road. I used to rest of the mesh grill and strapped it to a pair of old pants that I cut the back off of for chaps, they will stop you chain just as fast as any other chaps out there, trust me they save my life everyday. I use a chain grinder similar to the one posted above, I sharpen both ends of the cutter so when my chain gets dull from cutting up sheet metal to do body work on my car I just flip it around and rock on. The guy in the video looked like he hadn't put any bar oil in his saw. I use vegetable oil in mine...it smells great!
