A portable tool sharpener adapted for mounting on a rail such as may be found on various weapons includes a sharpener body in which a plurality of sharpening tools are mounted and a rail-mounting base pivotally mounted to the sharpener body to allow the body to moved selectively to a closed and open position, wherein the rail-mounting base is releasably engageable with a rail mounted on a weapon, a handle or a fixed pad.

A one-piece four-blade machined broadhead and sharpener for sharpening the blades of a four-blade broadhead is described. A broadhead may be machined as a single component from, for example, bar stock material. A broadhead of the present disclosure may be machined on a multi-spindle machine such as but not limited to a Swiss or Swiss-style screw machine. A broadhead may be machined in a reverse configuration such that an attachment end for attaching the broadhead to an arrow is positioned at or near an open end of the bar stock material. One or more steps of the broadhead machining or manufacturing process may be automated, for example by the use of one or more robotic gripping arms. Furthermore, a sharpener of the present disclosure may have sharpening stones positioned at angles such that a two blades of a four-blade broadhead may be simultaneously sharpened.

A cigar clipper sharpener includes a guide plate having a plurality of slots cut therein as well as a central sharpener support opening. A slender, angled sharpening tool can fit into the sharpener support opening, which may, itself, have a guiding surface to guide the sharpening tool at the proper angle for sharpening the blade of a cigar clipper. The plurality of slots allow cigar clipper supports to adjust to hold various sizes of cigar clippers on the guide plate. The retention members slide in the slots and can be positioned to hold both the body and the blade handles of the cigar clipper to the guide plate. The sharpener can be used on guillotine style, scissor style, callibri style and hole punch types of cigar clippers. The sharpener may be used on replaceable blades for replaceable blade cigar clippers.
