Abstract
A buttonhole scissors comprising a first blade having a blunt distal end and an inner flat surface between a tapered cutting edge and an outer edge, a second blade having a pointed distal end and an inner flat surface between a tapered cutting edge and an outer edge, these blades slidable over each other with each of the inner flat surfaces in close cutting engagement, a pair of handles for the blades pivotally connected, an intermediate portion of each blade provided with a notch arranged between the cutting edge and the pivot point and cooperating to form a noncutting area which receives cloth not to be cut, and an adjustable setting means mounted through one handle and contacting the other handle, and capable of adjustment to limit the movement of the blades relative to each other.

A method of cutting buttonholes comprising:
- a buttonhole scissors with a first blade having a blunt distal end arid an inner flat surface between a tapered cutting edge and an outer edge,
- a second blade having a pointed distal end and an inner flat surface between a tapered cutting edge and an outer edge,
- said first blade aria said second blade slidable over each other with each of said inner flat surfaces in close cutting engagement,
- a first handle of said first blade,
- a second handle of said second blade pivotally connected to said first handle,
- an intermediate portion of said first blade, provided with a first notch, said first notch being smooth and having a relatively constant depth, arranged between said cutting edge and its pivot,
- an intermediate portion of said second blade, provided with a second notch, said second notch being smooth and having a relatively constant depth, arranged between said cutting edge and its pivot,
