In the past I've used a couple far more expensive, extendable saws to prune. This saw is a bargain. The sections screw together and there is a spring-loaded locking pin for each section. Two very sharp blades are included, along with one plastic blade cover and a very nice canvas case. Over the past few days I used it to prune up to 4\" limbs as much as 18' high. There were four more sections that I did not use (start low and work up). Honestly this is a bargain, probably saving me $1000 in professional services. Now I am a pro!
