| 20090100683 | FIXED-BLADE KNIFE HAVING A MULTI-PURPOSE GUARD - A fixed-blade knife with a knife body comprising a blade having a cutting edge and an elongated handle exptending from the blade. A guard is pivotally coupled to the knife body and has a first and second position relative to the knife body. In other embodiments, the guard is slidably disposed along the knife body. In the first position, the guard is positioned adjacent the blade to at least partially cover the cutting edge. In the second position, the guard is positioned adjacent the handle to expose the cutting edge. A sharpening element may be disposed within the guard to hone and/or sharpen the cutting edge when the guard is pivoted relative to the cutting edge. | 04-23-2009 |

| 20110030223 | BAR MOUNTED SHARPENER - Embodiments include a sharpening fixture adapted to mount to the nose of a chainsaw guide bar. When mounted, the operator may direct a force towards the guide bar thereby causing a linear directed actuator to move a sharpening element into engagement with cutters of a saw chain to sharpen a cutting edge of the cutters. In various embodiments, the actuator is biased such that when the force is no longer applied, the actuator pulls the sharpening element out of engagement with the cutters. | 02-10-2011 |
| 20110192034 | CUTTING AND SHARPENING DEVICE AND METHOD - A cutting and sharpening device includes a body, a blade element having a cutting edge and rotatably mounted with respect to the body, and a sharpening tool configured to be removably coupled to the body. The sharpening tool can be selectively moved between a first position in which the sharpening tool is spaced from the blade element and a second position in which the sharpening tool contacts the blade element adjacent the cutting edge. The device can be used as a rolling cutter or slicer, and as a sharpening device that sharpens the blade element when the sharpening tool is coupled to the body. The sharpening tool can sharpen the cutting edge when it is in the second position and the blade element is rotated or rolled, directly or indirectly, on a surface. | 08-11-2011 |
| 20110289782 | Scissors and Sharpening Arrangement - The invention relates to scissors and a sharpening device. The scissors include two blades, each blade having a cutting edge and a back edge which respectively form opposite longitudinal edges of the blade. A pivot connects the two blades for relative movement of the blades between an open condition in which the cutting edge of each blade are apart and a closed condition in which each blade are substantially adjacent and the back edge of each blade projects beyond the cutting edge of the other blade. The blades also include a sharpening condition in which the cutting edge of each of the blades can be sharpened. A biasing means is included for biasing the blades away from the sharpening condition towards the closed condition and/or the open condition. The sharpening device is for scissors including two blades having a cutting edge. The sharpening device includes a hollow housing for receiving the blades of the scissors, a pair of positioning units within the housing arranged in an opposed relationship to receive the blades therebetween when the scissors are inserted into the housing, and a pair of sharpener units located within the housing arranged in an opposed relationship to contact the blades therebetween. | 12-01-2011 |
| 20120011726 | ROTARY CUTTER - A rotary cutter includes a rotatable cutter blade and a grinding element supported on a support at one side relative to the cutter blade for grinding the cutter blade. A gap is normally kept between the grinding element and the cutter blade. The support is operable to move the grinding element into friction contact with the rotating cutter blade when grinding is necessary during a cutting operation of the rotary cutter. The grinding element can be normally kept in friction contact with the cutter blade so that a grinding effect is produced when rotating the cutter blade during a cutting operation. | 01-19-2012 |
| 20120222313 | CHAIN LINK SHARPENING METHOD AND APPARATUS - Embodiments provide various components of a chain saw, including saw chain elements, sprockets, and other fixtures, that may facilitate sharpening of cutter links during operation. In various embodiments, the components may increase stability during sharpening, provide nose mounted sharpening fixtures, and/or facilitate the resizing and/or reshaping of a sharpening element. | 09-06-2012 |
| 20130025132 | CHAINSAWS - A self-powered chainsaw, typically a battery powered chainsaw, comprising a housing ( | 01-31-2013 |
| 20130205597 | KITCHEN KNIFE WITH SHARPENER - The kitchen knife with the sharpener includes: a cutout recess formed in an end of the handle; a locking space extending from the cutout recess; and a sharpener, including: a locking part removably received in the locking space; a sharpener body extending from the locking part; a whetting groove transversely formed in the sharpener body; plate-shaped whetstones inclinedly installed on opposing sidewalls of the whetting groove so that the whetstones form a V-shaped arrangement; and a rubber cushion placed below a rear surface of a whetstone. | 08-15-2013 |
| 20130326883 | SCISSORS AND SHARPENING ARRANGEMENT - The invention relates to scissors and a sharpening device. The scissors include two blades, each blade having a cutting edge and a back edge which respectively form opposite longitudinal edges of the blade. A pivot connects the two blades for relative movement of the blades between an open condition in which the cutting edge of each blade are apart and a closed condition in which each blade are substantially adjacent and the back edge of each blade projects beyond the cutting edge of the other blade. The blades also include a sharpening condition in which the cutting edge of each of the blades can be sharpened. A biasing means is included for biasing the blades away from the sharpening condition towards the closed condition and/or the open condition. The sharpening device is for scissors including two blades having a cutting edge. The sharpening device includes a hollow housing for receiving the blades of the scissors, a pair of positioning units within the housing arranged in an opposed relationship to receive the blades therebetween when the scissors are inserted into the housing, and a pair of sharpener units located within the housing arranged in an opposed relationship to contact the blades therebetween. | 12-12-2013 |
| 20140123499 | CHAIN SHARPENING DEVICE - A chain sharpening device arranged to sharpen a saw chain. The device comprises a housing ( | 05-08-2014 |
| 20140137414 | BLADE SCABBARD, SHARPENER AND SHARPENING CASSETTE - This invention relates to a blade storing device and blade combination. The blade includes opposite substantially parallel sides which meet at a cutting edge. The blade storing device includes a housing having an access opening at an end of the housing through which the blade can be moved longitudinally to be inserted into or withdrawn from the housing. The combination includes a blade restraining mechanism that includes a restraining member coupled to the housing and an opening within the blade, the restraining member having active and inactive positions. In the active position, the restraining member is positioned inside the opening within the blade for preventing withdrawal of the blade from the housing. In the inactive position, the restraining member is positioned outside the opening within the blade for allowing withdrawal of the blade from the housing. | 05-22-2014 |
| 20150298295 | FOLDING KNIFE WITH BUILT IN SHARPENER - Disclosed embodiments include a folding knife having a blade with a tip, a heel, and a cutting edge that extends from the tip to the heel. The folding knife also has a handle with an outer surface having at least one slot and a sharpener assembly having at least one sharpener element and at least one stud positioned in the at least one slot and that is graspable on the outer surface of the handle. Further, movement of the stud through the slot causes the sharpener assembly to traverse the blade along the cutting edge from the tip to the heel, or from the heel to the tip, and causes the at least one sharpener element to engage the blade. | 10-22-2015 |
