A surgical knife safety device having a handle, a blade connected to the handle, and a guard carried by the handle for sliding movement between a retracted position in which the blade is exposed for use, and an extended position for covering the sharp cutting edge of the blade. In the retracted position, an enlarged guard radius is provided at the distal end of the handle to allow improved handle control and blade orientation. The enlarged guard radius is positioned to allow the user to firmly grip a large distal handle portion which is preferably molded as a single piece with the blade holder, preventing unwanted blade or handle movement due to guard mechanism tolerances.

A surgical knife safety device having a handle, a blade connected to the handle, and a guard carried by the handle for sliding movement between a retracted position in which the blade is exposed for use, and an extended position for covering the sharp cutting edge of the blade. In the retracted position, an enlarged guard radius is provided at the distal end of the handle to allow improved handle control and blade orientation. The enlarged guard radius is positioned to allow the user to firmly grip a large distal handle portion which is preferably molded as a single piece with the blade holder, preventing unwanted blade or handle movement due to guard mechanism tolerances. A spring, such as leaf spring, and a pair of detents or slots are provided to fix the guard in the extended or retracted position, and provide resistance during movement between the two positions. Additionally, an antitravel mechanism is incorporated in the guard to prevent accidental retraction from the fully extended position.

The present device and method includes a handle, a blade connected to the handle, and a guard slidably mounted partially within the handle for sliding movement between a retracted position in which the blade is exposed for use, and an extended position for covering the sharp cutting edge of the blade. In the retracted position, an exposed guard radius is provided at the distal end of the handle to allow improved handle control and blade orientation. The exposed guard radius is positioned to allow the user to firmly grip a large distal handle portion which is molded as a single piece with the blade holder, preventing unwanted blade or handle movement due to guard mechanism tolerances. A leaf spring and detent is provided to fix the guard in the extended and retracted position, and provide slight resistance during movement between each position. Additionally, an antitravel mechanism is incorporated in the guard to prevent accidental retraction from the fully extended position.

A mailing machine including a base, a registration wall and a stripper blade. The base includes a deck defining a deck plane along which an envelope having an envelope body, an envelope flap and a top edge may be fed in a path of travel. The registration wall is located substantially perpendicular to the deck and parallel to the path of travel and along which the envelope top edge may be aligned during feeding. The stripper blade is located upstream in the path of travel from the deck, the stripper blade including a knife edge that is raised above the deck plane for separating the envelope flap from the envelope body.
