Abstract
A knife sharpener for the manual sharpening of knives that includes a knife clamp member having first and second clamping members, a guide member that defines upper and lower guide members, and a base member. Each upper and lower guide member includes a plurality of apertures sized and shaped for receiving a guide rod that includes a sharpening stone. The knife clamp member further includes embodiments assuring the knife blade is held securely and positioned between the first and second clamping members in the same position in which the knife blade was installed the last time it was sharpened.
Claims19
A knife sharpening device comprising:
- a knife clamp member that includes first and second clamping members,
- a guide member that includes an upper guide member and a lower guide member,
- a base member, and
- a sleeve member that defines a slit contoured for frictionally receiving a knife having a blade,
- said upper guide member upwardly extends from the knife clamp member and said lower guide member downwardly extends from the knife clamp member with a ledge therebetween, and wherein said lower guide member joined to said base member, and wherein said upper and lower guide members each including at least two (2) columns of apertures sized and shaped for receiving a guide that includes a sharpening stone,
- said first clamping member having a distal end that includes at least one aperture that mates with at least an equal number of protrusions on said sleeve member such that said sleeve member is selectively received between the first and second clamping members and fixedly secured with at least one tightening screw, and wherein said first clamping member defines a first length that extends from said distal end of said first clamping member to said ledge of the guide member such that an opposite end of the first clamping member abuts a front end of said ledge, and wherein said second clamping member defines a second length that extends from a distal end of the second clamping member and extends through an open slot disposed in a lower surface of said ledge such that an opposite end of said second clamping member abuts a frontal surface of the guide member, and wherein said opposite end of said second clamping member is appropriately attached to said ledge such that said second clamping member is fixed to said guide member and said first clamping member configured to tighten to said second damping member.
