Specific embodiments of the present invention are directed to blade holders, which provide an easier method to cut by way of including a guide incorporated into the handle. This guide rests upon the surface to be cut, leading the cutting blade. Furthermore, the leading end of the tool is blunt, which is safer than leading with a sharp edge. In specific embodiments, the handle is of such a shape that the user can pull the tool straight back to cut, allowing the hand to rest in a more neutral and ergonomic position.
1. A blade holder, comprising:
a handle;
a leading edge extending from said handle;
a guide connected to said leading edge wherein said guide is adapted to maintain contact with a cutting surface,
wherein said guide is further comprised of a blade storage compartment configured to store replacement blades,
wherein said blade storage compartment is further comprised of a cantilevered beam configured to secure said replacement blades in said blade storage compartment,
wherein said cantilevered beam is further comprised of a mating feature that is integrally formed at the distal end of said cantilevered beam,
wherein said mating feature is configured to detachably engage with a notch formed in each of said replacement blades;
a trailing edge extending from said handle in a direction substantially opposite from said leading edge;
a blade slot positioned within said trailing edge such that an exterior opening of said blade slot is parallel with said guide;
a blade retractably positioned within said blade slot; and
a blade actuator wherein said blade actuator controls the extension and retraction of said blade.
2. The blade holder according to claim 1 wherein said blade is completely contained inside said trailing edge when said blade is in a retracted state.
3. The blade holder according to claim 1 wherein said blade extends a set distance beyond said exterior opening of said blade slot when said blade is in an extended state.
4. The blade holder according to claim 1 wherein said blade is made of zirconium oxide.
5. The blade holder according to claim 1 wherein said trailing edge is further comprised of a slidable body portion that allows for the replacement of said blade.
6. The blade holder according to claim 5 wherein said trailing edge is further comprised of a cover lever arm that prevents movement of said slidable body portion unless said blade is fully retracted.
7. The blade holder according to claim 1 wherein said trailing edge is attached to said handle via a connection means.
8. The blade holder according to claim 7 wherein said connection means allows said trailing edge of said blade holder to collapse towards the leading edge of said blade holder.
9. A blade holder, comprising:
a handle;
a leading edge extending from said handle;
a guide connected to said leading edge wherein said guide is adapted to maintain contact with a cutting surface,
wherein said guide is further comprised of a blade storage compartment configured to store replacement blades,
wherein said blade storage compartment is further comprised of a cantilevered beam configured to secure said replacement blades in said blade storage compartment,
wherein said cantilevered beam is further comprised of a mating feature that is integrally formed at the distal end of said cantilevered beam,
wherein said mating feature is configured to detachably engage with a notch formed in each of said replacement blades; and
a connection means connected to said handle in a direction substantially opposite from said leading edge,
wherein said connection means is designed to removably receive a utility knife.
10. The blade holder according to claim 8 wherein said connection means is a hinge.
11. The blade holder according to claim 9 wherein said hinge allows said trailing edge of said blade holder to collapse towards the leading edge of said blade holder.
12. A blade holder, comprising:
a handle;
a guide connected to said handle wherein said guide is adapted to maintain contact with a cutting surface,
wherein said guide is further comprised of a blade storage compartment configured to store replacement blades,
wherein said blade storage compartment is further comprised of a cantilevered beam configured to secure said replacement blades in said blade storage compartment,
wherein said cantilevered beam is further comprised of a mating feature that is integrally formed at the distal end of said cantilevered beam,
wherein said mating feature is configured to detachably engage with a notch formed in each of said replacement blades;
a blade portion extending from said handle in a direction substantially opposite from said guide;
a blade slot positioned within said blade portion such that an exterior opening of said blade slot is parallel with said guide;
a blade retractably positioned within said blade slot; and
a blade actuator wherein said blade actuator controls the extension and retraction of said blade.
13. The blade holder according to claim 11 wherein said blade extends a set distance beyond said exterior opening of said blade slot when said blade is in an extended state.
14. The blade holder according to claim 11 wherein said guide is further comprised of a blade storage compartment.
15. The blade holder according to claim 11 wherein said trailing edge is attached to said handle via a connection means.
