What is Whetstone?

Whetstone is basically a piece of a rectangular block of stone/rock, that is used to sharpen and hone the edge of knives and other metal tools such as machetes, chisels or axes. Any stone used for sharpening purpose was called a whetstone before. But nowadays, the terms sharpening stone or honing stone have largely replaced by whetstone, but you will still hear it used occasionally. It should keep in mind that; all types of water stones or oil stones are whetstones but all whetstones are not water stone or oil stone.

Whetstone or wet stone which is correct? The question arises because of the words wet and whet sound alike. Actually, they are different, and this is a common source of confusion. The proper word actually is whet, when used about sharpening stones. Whet means to sharpen.

Material of Whetstone

There is a variety of materials used to create whetstones, some are natural, others synthetically produced. Most synthetic stones are composed of aluminum oxide or silicon carbide. Whereas natural stones are typically formed of microcrystalline quartz such as novaculite. Synthetic stones perform better than natural stone but pricy. Natural stones perform better after soaking but synthetic whetstone can shorten its lifespan if you soak it for long times.

Arkansas sharpening stone and Japanese whetstone are prominent natural stones. Whereas, Diamond whetstones and Ceramic sharpening stones are the most common synthetic whetstone.

Whetstone Grit Sizes

The grit size of the whetstone is usually defined as the abrasive quality of the stone. There’s three different grit/grain size of whetstone- coarse grit, medium grit, and finer grit. The smaller the grit value, the coarser the stone. A coarse grit (a lower number) will remove a lot of particles from the blade whereas finer grit (a higher number) is used for finishing an edge smoothly.

There are different types of standards for grit sizes. You will find JIS, CAMI, ANSI, FEPA-P (for sandpaper), FEPA-F (for metal abrasives). Additionally, different trademarked standards for different company are also available in the market.

Step 4: Start with the coarse side

If your knife is highly dull, then start sharpening with the coarse side otherwise finer side. (Here, we’re starting with a coarse side). Note that, you can sharpen a blunt knife entirely using a finer grit, but it will take much longer than starting off with coarse grit and moving onto a finer ones for finishing.

Step 5: Sharpening angle consideration

Place your blade at an angle of 30-35 degrees on the stone if you are sharpening your machete or kukri. Sharpening angles differ from blades size and shape. Hunting knives, pocket knives, survival knives, and sport knives require an angle of 25-30 degrees. Sharpening angle for chef’s knives, kitchen knives are 17-25 degrees. Most Japanese cutlery requires 12-17 degrees while straight razors angle is 7-12 degrees.

Step 6: Sharpen the first side

Firmly hold your knife with first hand and apply suitable pressure by the off-hand. Then, draw the blade along the stone from tip to handle until sharpened nicely. Repeat the actions several times.

Step 7: Switch over the blade’s second side 

Switch over your blade and repeat step 6 for sharpening its other side.

Step 8: Check knife’s sharpness

Check your knife’s sharpness. Carefully run your thumb perpendicular to the blade or cut some pieces of paper to check its sharpness.

Step 9: Sharpen with the finer side

If you feel the edge is sharpened enough with the coarse side, then flip over your stone to the finer side and repeat step 5,6 and 7 for a more smooth edge. Before flip over your stone be sure the stone is still wet. If it’s not, just splash some water on it, you needn’t re-soak it.

Step 10: Finish sharpening and clean it

After sharpening is done, clean both the whetstone and knife by removing metal particles and keep them in a dry place.
