The disclosure discloses a knife sharpener that can sharpen knives simultaneously on rough and fine grinding position of the knife sharpening seat, comprising a knife sharpening seat, a cover plate, a knife sharpening groove and a fine grinding column, wherein the upper end of the knife sharpening seat is provided with the cover plate; the lower end of the sharpening seat is provided with a bottom fixing column; the inner bottom surface of the cover plate is provided with two sets of connecting columns; two gears of rough and fine grinding positions of the device can be selected according to the wear degree of the knife blade to carry out the sharpening operation, or the rough and fine grinding positions can be used for sharpening operation at the same time, thereby improving the convenience of operation and occupying very little space.

A clamping apparatus has first and second clamping members extending in an opposed, spaced-apart relation along a central axis from proximal end portions to distal end portions with inside surfaces of the clamping members facing each other. A gap between the proximal end portions is adjustable to releasably secure an object between the distal end portions. A clamp actuator has a handle and a wedge, moving the handle to a first handle position moves the wedge linearly along the clamp central axis in engagement with the inside surfaces of the proximal end portions to increase the gap. Moving the handle to the second handle position moves the wedge in an opposite direction along the central clamp axis, thereby permitting the gap to decrease. In embodiments, the clamping force is adjustable.
