Abstract: An electric sharpener for sharpening ceramic blades includes at least one stage. The stage is a finishing station having a sharpening member in the form of a disc which comprises a rigid support having a flexible abrasive matrix which both sharpens and polishes the facet of the ceramic blade. The sharpener may include a pre-sharpening stage for metal blades and a further pre-sharpening stage for ceramic blades. The sharpener also includes a removable guide.

Abstract: A knife sharpener sharpens a wide range of knives and blades. The knife sharpener includes an angle guide associated with a first stage abrasive surface at an angle in the range of 12-18 degrees. A second stage is provided at an angle in the range of 17-23 degrees. A third stage is provided at an angle in the range of 19-25 degrees. The abrasive surface in the first and second stages is in the range of 240 to 400 grit while the abrasives in the third stage is in the range of 600 to 2000 grit.
Abstract: A combination sharpener assembly which is particularly useful for fishermen, includes an electrically powered knife sharpener. A manually operated scissors sharpener is mounted in the recess of the housing for the knife sharpener. A hook sharpener is detachably mounted in a compartment in the housing of the knife sharpener. The motor for the knife sharpener is mounted in a sealed inner housing and can be selectively operated under either direct current or alternating current.

Abstract: A knife edge enhancing apparatus includes a support having a support surface and knife blade clamping structure mounted to the support and located above the support surface. An object having a knife edge modifying surface which could be abrasive or non-abrasive is mounted to a holder which is freely slidable on the support surface so that the object surface can be manually moved into contact with a knife edge facet. At least one of the clamping structure and the object surface is angularly adjustable to control the angle of contact of the object surface with the knife edge facet.

Abstract: A vessel for preparing heated water or other liquid includes a container, an electric heater and a temperature sensing probe mounted through a wall of the container. The probe includes an efficient heat transferring structure in direct thermal contact with and wet by the liquid. An electrical sensor within the probe is in intimate thermal contact with the transferring structure and has electrical properties directly correlating with the temperature of the transferring structure. The transferring structure is attached to a supporting structure mounted to the wall by an elastomeric efficient thermal insulating material held in compression providing physical support for the probe and sealing the wall from leaking and insuring that the sensor is primarily thermally responsive to the temperature of the transferring surface and to the liquid but is thermally insulated from variations in the temperature of the supporting wall.

Abstract: An apparatus for manually steeling or conditioning the edge of a knife blade comprises a precision angle guide attached to a manual sharpening steel. The angle guide establishes a guiding surface that provides for sustained sliding or rolling contact with the face of the knife blade such that the plane of at least one edge facet adjacent to the edge of the blade is maintained at a precisely established angle relative to the plane of the sharpening steel surface at the contact point of the facet with the surface of the sharpening steel.
