Zusammenfassung:	A fixture for cutting and inwardly bending the ends of spiral binders. The fixture comprises a body having parallel sides formed by a milled slot, the lower end of one side having an arcuate inward extension. A cutter pivotally mounted between the body sides has a complementary portion adjacent the curved extension and another portion spaced from the other side. The construction enables the end of a small diameter spiral having a large pitch to be trimmed in a manner which bends the end of the spiral inwardly a sufficient distance to bridge the gap to the next turn, thus preventing snags when books are stacked.
