I used one of these at a summer job cutting fabric in a J.J.Newberrys Store, back a whole bunch of years ago. The large roller machines do not snip and cut, they just measure and then you cut with scissors. (FYI - if buying the rolled fabric, please insist they use the roller - you can not accurately cut a 54" roll on a 40" table!). The days of snip and tear went away with the all cotton, known quality fabric. Just try to tear a fabric with any poly in it or a poor quality cotton. Even if it rips sort of straight, the tear will so distort the fabric that you will never iron it back in shape.
