And the saw on the multitool is way too small to be really effective. Just watch Michel Blomgren manage to build a shelter with only his Victorinox multitool. Better is a folding saw like the Gerber or Bahco Laplander (there are cheaper alternatives at stores like Homedepot). Mors Kochanski advocates that a survival saw is a swedish flexible bucksaw blade and must be ideally as long as from your nose to your finger tips (about the lenght of an arm) to take advantage of a full stroke of your arm so the lenght should fit yourself (I'm tall so I guess 30 inch would be my lenght) and that you can carry on your belt or roll it and then build a wooden frame. He says that it must be able to cut a "hug-size tree". I wonder what hug-size actually means but I got an idea.
interesting collapsible wooden bucksaws BTW, is this a "hug-size" tree?
