Abstract
A razor blade tool relating to overcoming single use shortcomings of current utility knives allows a user to select multiple razor blade positions. Each razor blade position allows a razor blade tool to be utilized for a different purpose, such as scraping, case cutting, twine cutting, and as a knife. Additional razor blades are stored in a razor blade tool in a manner that prevents the sharpened edges of razor blades from contacting side-walls of the storage area so that stored razor blades remain sharp and undamaged.
Claims18
A razor blade device comprising:
- a handle portion;
- a razor blade housing connected to the handle portion;
- a razor blade carrier for holding a razor blade rotatably mounted within the razor blade housing such that the razor blade carrier is rotatable within the razor blade housing to a plurality of positions, wherein the razor blade housing covers substantially the entire razor blade carrier;
- a razor blade storage area in the handle portion configured to store at least one razor blade such that a sharpened edge of a stored razor blade does not contact side-walls of the razor blade storage area;
- and
- a cover movably connected to the handle portion to provide access to the razor blade storage area.
