ABSTRACT:
A portable sharpener for sharpening a blade, which has at least one cutting edge, has an elongated body with a guiding channel where the blade can be inserted therethrough and guide the sharpener along the blade side walls during sharpening. The elongated body has a chamber dimensioned to house and hold an elongated abrasive member. A portion of the abrasive member is exposed through the channel to enable the blade edge to engage the abrasive member. The chamber also has a space to capture the blade filings or fragments. A movable guide having another channel is pivotally secured to the body such that the guide can pivot relative to the body. The movable guide channel remains always aligned with the guiding channel of the body such that the body housing the abrasive member can rotate relative to the movable guide, the channel of which engages the blade, to enable the sharpener to move around a curved portion of the blade during sharpening while the abrasive member is positioned at a proper angle relative to the curved portion of the blade.
