I broke my saw that I have been carrying for the last 10 years or so. It never really got much use, and was kinda cheaply made. A gerber exchange blade that is mostly plastic. So I did some "research" on youtube, but typically find either a boning saw or a brush saw. What I want is one saw that fits this criteria: 1. Has two different type of blades (easily changeable, for in the field), one for brush cutting and one for bone. 2. Is lightweight (to set a bench mark, let's just say less than 14 oz). 3. Foldable but must be strong. 4. Preferably has a sheath. Bonus would be if the sheath held the saw and an extra blade or two. Not to concerned about cost, lets say up to $100. Which I would imagine would cover any non-custom saw for this purpose. Anyone out there got one they use and would recommend.
