A guided two sided honing rod that holds Japanese style edges straight between sharpenings. It realigns an edge but will not restore a blade that has gone dull.

A countertop sharpener with a diamond slot for pizza wheels plus coarse and fine knife slots, for kitchens that use both. Angle and grit details are not given.

A compact pull-through sharpener that handles routine edge maintenance on straight and serrated kitchen knives without any technique to learn.

A hands-free knife sharpener that suctions to a countertop and pulls a working edge back onto a knife in a few passes, no batteries required.

A compact, unpowered sharpener that reviewers credit with reviving genuinely dull knives and scissors, worth having on hand for routine touch-ups.


A 4-stage pull-through sharpener that also handles scissors, with a safety glove included, aimed at quick touch-ups rather than a fine hand-set edge.

A fast pull-through sharpener for straight and serrated kitchen knives, with reversible carbide blades that AccuSharp says last most users 5 to 10 years.

A small, preset-angle field sharpener for touch-ups on knives that are already reasonably sharp, not a substitute for a full sharpening kit on a badly dulled blade.

A wider-scope sharpener than most kitchen-only options, worth it if axes, shears or mower blades are part of the sharpening list alongside knives.


A straightforward honing rod for maintaining an edge between real sharpenings, comfortable in either a right or left hand.


A 4-stage pull-through sharpener that covers repair, sharpening, polishing, and serrated blades in one handle, reviewed as easy to use though at least one buyer found it did not sharpen well.


A multi-angle pull-through sharpener that covers straight kitchen, pocket, and hunting knives, but it will not touch a serrated edge.


A straightforward way to get a consistent factory-style edge back without whetstone technique, provided your knife suits one of its two fixed angles.

A manual sharpener with four preset angles and a ceramic stone, a sensible tool for a drawer of mixed blades. Serrated edge support and grit are not stated.

A two-sided water stone with a coarse side for reshaping and a finer side for polishing, set in a non-slip base for steady sharpening. It needs a practiced hand, since no angle guide is listed.


A fixed angle rolling sharpener with a diamond stage, a ceramic stage, and a leather strop, built for straight kitchen knife edges rather than serrated blades or scissors.
