A blade scraping tool including a hand gripping casing formed of a top covering and a bottom covering connected to each other; a resilient plate mounted inside the hand gripping casing; a blade; a blade mounting device on which the blade is mounted; and an interlocking assembly. The casing includes a slot extending centrally and longitudinally on the top covering. The resilient plate is mounted inside the hand gripping casing and is slidably movable along the same. The resilient plate has a push button which extends outwardly from the casing through the slot and which is slidably movable therealong. The blade mounting device on which the blade is mounted is affixed to a front end of the resilient plate and is positioned and devised to slide through a front opening of the casing. The interlocking assembly cooperates with the resilient plate and the top covering for locking the plate and the blade into different working positions. A retracted position, where the blade is entirely encased within the casing, is attained by actuating the push button onto a first position along the slot; whereas an operating position, where the blade is exposed through the opening of the casing for operation of the tool, is attained by actuating the push button onto a second position along the slot, the second position being closer to the front end of the casing than the first position. A blade release position is attained by actuating the push button onto a third position along the slot, this third position being closer to the front end of the casing than the second position and allowing mounting and removal of the blade to and from the blade mounting device. The blade scraping tool preferably includes also a peripheral elastomer rim mounted along a portion of a periphery of the casing formed by the top and bottom coverings. The blade scraping tool is lightweight, sturdy, easy to operate, and provides ergonomic hand gripping and may also be provided with a long lasting logo.
