I like the wire saw for training young trees with tight crotches, does very little to no collateral damage. Chain one could work well in similar situation especially when a plunge cut with a chainsaw or using a handsaw could cause more collateral damage.
Anyone try it?
How can a hand saw cause more collateral damage? This makes no sense. Saw chain on a rope is a bs tool marketed to the masses as a miracle tool that will change your life! As a survival tool, go for it. My guess, is this tool will one day get pulled from the market as a result of numerous lawsuits due to injury or death by homeowners dropping limbs on themselves.
