Ceramic Sharpening Rods

As you use your knife, it develops tiny ‘burrs’ which are rough bits of the edge that have bent out of shape. Ceramic gently pushes them back into alignment, straightening the edge without removing steel unnecessarily. These means that your knife stays sharp much longer, without having to be sharpened as often.

Ceramic sharpening “steels” will never wear out, but the surface can get clogged with removed metal particles. This can be cleaned out with a scouring pad to render them as good as new. If banged against things, the brittle ceramic can chip permanently, but that is not part of normal use.

Ceramic rods fall somewhere between honing and sharpening depending on their grit. A ceramic grit around 400-800 is sharpening your knife. A grit around 2000 is honing your knife.

Electric Sharpeners

Electric knife sharpeners are user-friendly and speedy, generally offering multiple sharpening options for a variety of blades.

When it comes to sharpening, some prefer using an electric knife sharpener for whatever reason. It is faster than manually sharpening when time is a factor. 

Some electric knife sharpeners use multistage technology to produce custom knife edges suited for particular cutting tasks. Sharpeners work on smooth, serrated, kitchen, Asian, and sporting knives.

There are many different brands and styles of electric sharpeners in the market and it all depends on the type of knives you’re looking to sharpen and what your goal is. Some are made to put a new edge on your blade or completely redo the edge as a new edge.

Handheld Sharpeners

Also known as pull thru sharpeners, these sharpeners are great when you need a fast sharp edge on your knife.

A handheld knife sharpener is a compact, packable knife sharpener designed for sharpening on the go. The diamond sharpening plate and ceramic honing rod use built-in angle guides to create a sharp edge anytime, anywhere.

Pull the knife through the course slot of the sharpener, from the heel to the tip, using even pressure, three to six times (pull through more times for more dull or damaged knives).

Depending on how the handheld sharpener is designed, you either draw the knife through the slots while the sharpener is placed on a flat surface, or the sharpener is drawn down the length of the blade while the knife is carefully held spine-down on a table or countertop. Both types of handheld sharpeners easily sharpen a dull knife back to perfect cutting form.

Sharpening Kits

Sharpening system kits is a handy set of stones ranging from different grits along with the proper equipment to mount and execute the precision knife sharpening you need for you cutlery.

They range in the types of styles you need. It can be a 2pc, 3pc, 4pc or a 5pc  stone grits suited for each task.

The grits range from Extra-Extra Fine, Extra-Fine, Fine, Medium, Coarse, and Extra-Course alumina-oxide stones and ceramic stone.

Most of them come with a handy portable storage carrying case that’s either made of Cordura mesh or hard plastic.

Sharpening Steel Rods

A sharpening steel removes material from your knife. By moving the edge alongside the steel remove steel to restore the V-shape of the edge. A sharpening steel can therefore be used to sharpen knives that have become blunt after frequent use.

A honing steel will re-align the microscopic teeth and can be used frequently- even after each use. A sharpening steel will actually take a small amount of steel off the blade, creating a new edge. 

Depending on use, the average knife needs to be sharpened every 1-2 months. Sharpening, is the process of restoring a damaged or dulled edge and requires a fairly coarse abrasive such as a diamond plate, stone, or abrasive belt.

To maintain the beautifully sharpened blade you just worked so hard to get, you’ll want to hone your blade after sharpening (and after each use).


The tri-stone bench stone uses three different sharpening elements in one package for the best results when sharpening.

These oil stones use a mineral oil type of lubrication.

Each tri-stone system has a different types of stone grits. These stones could be an Arkansas surgical stone which is a medium stone and fine stone for honing and the third stone would probably be a coarse stone for a more aggressive maintenance. It all depends on the style of tri-stone system.

Each stone is mounted on an easy to use molded plastic triangle, that is rotated depending on which stone you wish to use. (Each stone type is clearly labeled on the plastic mount, so there is no confusion there.)

To complete the functional design the tool is held upon a sturdy molded plastic base, that is weighted well enough to hold position on the work counter. Non skid rubber feet fasten the sharpener when in use.

These are normally used by chefs, culinary students/schools and of course a sharpening hobbyist.

Water Stones

Water stones are a tried-and-true tool used to repair, sharpen, and polish kitchen knives.

Synthetic or artificial whetstones are made with bonded abrasives. These are commonly aluminium oxide, silicon carbide (a type of ceramic), or a diamond coating mounted on a metal sheet. Synthetic whetstones offer a consistent grit size, which allows for faster, more effective sharpening.

Natural whetstones are typically formed of quartz, such as novaculite. The Ouachita Mountains in Arkansas are noted as a source for these. Novaculite is also found in Syria and Lebanon, previously a part of the Ottoman (Turkish) empire.

Often whetstones are used with a cutting fluid to enhance sharpening and carry away swarf. Those used with water for this purpose are often called water stones or waterstones.
