  • Patent number: 8938883
    Abstract: A folding knife for applying a cutting action includes a blade assembly having a guard configured to cover the cutting edge of the blade when the knife is not in use. The guard is maintained in a normally blade covered position by a resilient member. The blade guard has a guard actuator for providing at least one motion for a user to move the blade guard from the normally blade covered position to an un-guarded or cutting position. The knife further includes an actuator for unlocking the blade assembly from the closed position to a locked open position. Upon depression of the actuator, the blade assembly will automatically open to a locked open position from a locked closed position.

  • Publication number: 20130324019
    Abstract: A sanding device for use with sandpaper sheets comprises a base connected to two lateral extensions by flexible connectors. The base further includes a plurality of spikes pointed towards the extensions and positioned inside slots in the extensions when the device is in a closed position. In order to load and unload sandpaper sheets, a lateral extension may be lifted against a tension force from the flexible connector. The stress on the flexible connector is limited by the contact of two edges which are positioned to prevent the flexible connector from undergoing stress beyond a specified level.

  • Patent number: 8375588
    Abstract: A preferred embodiment of a safety carton cutter comprises a first frame member pivotably connected to a second frame member to form a housing. Inside the housing mounted on the first frame member is a blade receptacle having a latch, a blade carrier, a biasing member and a follower. The follower is adapted to communicate with a cam profile located on a cam in the first frame member. The configuration of the follower and cam profile provides an extending and retracting mechanism that keeps the blade in a constant exposed position before and during the cutting process, and then allows the blade to retract immediately after the cutting process is complete.
