| 20090235537 | Blister package opener - An opener for a blister package or for cutting of other planar material is disclosed. A cutter pair is provided adjacent an engagement area. When blister package layers are fed into the engagement area, the cutter pair including a top cutter and bottom cutter rotate to feed the package material through the engagement area. The cutters are closer together than a thickness of the package. At least one of the cutters includes a knife thereon to cause cutting of the material as it is fed between the cutter pair. A handle is provided supporting a head which has the cutter pair thereon. A motor provides power to cause rotation of the cutter pair through a gear set.

| 20080282551 | Cutting Devices - Hand-held cutting devices including a body having a handle portion and a cutting portion, and one or more rotatable cutting blades arranged on the cutting portion. The cutting portion is movable into different positions relative to the handle portion, or vice versa. When two cutting blades are provided, they may be arranged on opposite sides of a mounting wall and axially offset from one another. To prevent the user from being cut by one cutting blade when the other cutting blade is being used, yet still enable both cutting blades to be used when desired, a blade guard is movably connected to the cutting portion and movable between two positions in which it is alongside all of one cutting blade (the one not being used) but not all of the other cutting blade (the one being used), and vice versa. | 11-20-2008 |
| 20090260236 | KNIFE OF A BLENDER - This invention relates to a knife of a blender that includes a container, the knife fixed on a bottom of the container, and a base located under the container. The knife is provided with an upper blade having its ends inclined upward, a lower blade having its two ends inclined downward, and a shearing blade installed between the upper blade and the lower blade. Each of the upper blade and the lower blade has a shear edge used as a cutting means. The shearing blade is shaped similar to “S”, provided with two shearing edges symmetrically formed on two end portions, and a plurality of teeth formed along each of the shearing edges with diverse depth. By means of the knife, frozen or semi-frozen fruits can be finely crushed quickly, and fruits and vegetables can be completely blended into juice. | 10-22-2009 |
| 20160075042 | SAFETY CUTTER FOR JAM PREVENTION - A safety cutter for jam prevention for preventing an object being cut from being jammed when the direction of a disc-shaped rotary cutting member is switched especially in a diagonal or curved line, as well as cutting the object while the disc-shaped rotary cutting member is traversing and rotating about a center of the object being cut by means of simple pushing force without needing scissoring. The safety cutter includes a cutter body, disc-shaped rotary cutting members, and fastening members. In the cutter body, an open slit is formed on the front of the cutter body, coupling holes are respectively formed on the top and bottom of the open slit, and a grip part is formed on the rear of the cutter body. | 03-17-2016 |
| 20160136828 | EDGER - An edger for trimming an excess portion of a laminate extending beyond an edge of a substrate includes a housing having a slot for receiving the excess portion, a first adjustable cutting wheel configured to ride along the edge of the substrate below the excess portion and a second fixed cutting wheel configured to be disposed above the excess portion. The first and second cutting wheels cooperate with each other to pinch and cut-off the excess portion as the edger is slid along the substrate. | 05-19-2016 |
