I had about three of the standard saws and they would quit holding the blades after a while. I purchase a new concept saws and love it. I had a little trouble with the bottom screw but was able to repair it. Don't want to give it up now.

I also love the Knew concept saw frames. The extreme light weight of the aluminum frames is eyes opening and sooooo comfortable to use. Working an offset steel frame vs the aluminum frame is much less stressful on my 60-year old wrists.. Anything to reduce the negative effects of repetitive motion syndrome will serve you well. I purchased early models and later converted them to the lever tensioning system.
