Shear sharpener

A shear sharpener, comprising:

• a horizontally elongated base having first and second upwardly opening socket means spaced apart lengthwise of said base;
• swivel means having a lower part depending into and received by the first socket means and an upper part fixed to and rising from said lower part, said upper part including a swivel element mounted for movement about a plurality of intersecting axes and having a through opening on an axis spaced above the base;
• vise means including a post depending into and received by the second socket means, a fixed jaw rigid with and rising from the post, a movable jaw cooperative with the first jaw for receiving a shear blade between them and clamp means selectively operative to close and open the jaws;
• means for securely locking the vise means to the base via said post and second socket means with the jaws transverse to the base;
• and hone means disposed above the vise means and including a shaft slidably received by the opening in the swivel element, at least one honing stone fixed to the shaft as an elongation thereof, and a handle attached to the stone for manual reciprocation of the hone means across a shear blade held by the vise means, said swivel enabling said reciprocation of the hone means as well as movement of said hone means transversely of the base and also enabling vertical movement of the hone means relative to the vise for lifting of the hone means clear of the vise;
• and wherein the means for locking the vise means post to the base includes an opening in the base transverse to said second socket means and a releasable locking element received in said opening and having a key-way embracing the vise means post within said socket means.
