A pencil sharpener is disclosed. The pencil sharpener comprises: a housing part which has an accommodation space thereinside with an open portion formed on one side thereof, and in which a first coupling member is formed on an inner side surface thereof; and a pencil sharpening part which is inserted into the accommodation space of the housing part, has a second coupling member corresponding to the first coupling member formed on an outer side surface thereof, and has a knife blade part thereinside, wherein a pencil, which is inserted into the pencil sharpening part, is sharpened by the knife blade part as at least one area of the pencil sharpening part is rotated by the first coupling member and the second coupling member as a pencil, which is inserted into the pencil sharpening part, makes a straight-line motion in the lengthwise direction of the housing part.

A pencil cutting tool 1 comprising a recess forming part 10 for boring a connecting recess 52 in an end face 51 of a pencil 50, wherein the recess forming part 10 comprises a main body 11 having a cylindrical insertion hole 12 for insertion of an end of the pencil 50 and a boring blade 40 disposed inside the insertion hole 12 so as to come into contact with the end face 41 of the pencil 50, the boring blade 40 has a semicircular cross section and a flat surface 40a extending along the axial line of the insertion hole 12, and the main body 11 has a discharge part 13 that is formed so as to face the flat surface 40a to discharge shavings from the insertion hole 12.

A pencil sharpener includes a main unit including a main body and a pencil sharpening device, and an outer shell detachably sleeved on the main body. The main body includes a bottom base, a supporting seat and an engaging member. The supporting seat includes a surrounding wall extending upwardly from a periphery of the bottom base, and a top wall connected to a top end of the surrounding wall. The pencil sharpening device is detachably disposed between the bottom base and the top wall. The engaging member is fixedly disposed on the surrounding wall. The outer shell includes an inner surface frictionally abutting against the engaging member. The outer shell and the surrounding wall cooperatively define a shaving collecting room.

A pencil holder is disclosed. The pencil holder may include a housing having a first receptacle for receiving a distal end of a pencil. The pencil holder also includes a heating element disposed within the housing for heat the distal end of the pencil.

The present invention relates to a device and a method associated with the device. The device is a carpenter speed square generally comprised of a flat triangular frame with one 90 degree angle and two 45 degree angles. The frame has a flange that protrudes outward from its top and bottom faces along one of the edges adjacent to the 90 degree angle. The device has an integrated means for sharpening pencils. With respect to the associated method, the user holds the device in their non-dominant hand with that hand wrapping around the flange with the right angle on the side adjacent to the thumb. Using their dominant hand and the integrated pencil sharpener the pencil is sharpened. Once sharpened, the pencil will be in the users dominate hand and the device will be in the uses non-dominate hand which is conducive to common layout and marking operations.
