I love my Mikita Sawz-all ("reciprocating saw"). Right now we're (the wife and I) replacing steel "Finestra" (made in Detroit!) windows with very nice new ones. Due to the nature of the steel window install (in 1941), I have to bust out all the glass, and then saw the steel frames with my sawz-all and collapse the suckers. Then we clean up all the mess, and install the beatiful new Pozzi windows. Which are extemely heavy, but a good architectual replacement. Without the Sawz-All, it'd be rough going so... Hip Hip Hooray! For the Sawz-All and it's many fine functions.
