A retractable blade scraper includes a handle body having a handle rear end and a handle forward end including a forward-end opening. An internal blade-slide cavity extends rearwardly from the forward-end opening toward the handle rear end and is configured to selectively receive a blade through—the forward-end opening. A blade slide housed by the blade-slide cavity includes lower and upper blade slide members between which the blade is selectively retained. A blade-slide actuator is accessible through an actuator slot defined through a wall of the handle body between slot first and second ends. Reciprocation of the actuator between the slot first and second ends reciprocates the blade slide between a rearward blade-storage position in which the blade is housed in the blade-slide cavity and a forward blade-changing position in which the blade protrudes through the forward-end opening to facilitate blade changing. The actuator includes threadably cooperating members that facilitate the alternative clamping of a blade between and release of a blade from between the blade slide members when the blade slide is in the blade-changing position. A spare-blade storage drawer is housed within a blade-storage cavity and is accessible through a rear-end opening in the handle body.
