English: Skil is a brand of power handtools produced by Robert Bosch GmbH. The line traces its heritage to the invention of the portable circular saw, marketed as a Skilsaw. The Model 77 which evolved from it set the industry standard for handheld direct-drive and worm-drive circular saws and remains in production almost unchanged today. In an example of a genericized trademark, portable circular saws are often still called Skilsaws or Skil saws.
