Abstract
A compact, ergonomic, lighted, retractable seam ripper is provided, having a housing, a retractable seam ripping blade, an LED, a battery, and a switch. The housing has generally planar exterior sidewalls and lower peripheral surface, a generally arcuate upper peripheral surface, a blade opening in the upper surface, and a longitudinally extending first and second rail generally parallel to the lower peripheral surface. The retractable seam ripping blade is mounted on a blade holder translatable along the first rail. A spring integral with the holder has a locking projection that engages locking depressions in the second rail. An actuating member between the spring and housing dislodges the locking projection from each of the locking depressions. The switch connects the LED to the battery when actuated.
