A good, quality knife or cutting tool should last you a lifetime. You may notice, though, that your knife can dull over time, providing you with less effectiveness and an increased risk of accident. No need to worry — that’s what a whetstone is for. Sharpening stones will help keep your cutting tools stay sharp and shiny to supply you with the longevity you expected.

A whetstone is man’s best friend when it comes to keeping your cutting tools performing at a high level. Initially, you might become overwhelmed with the variety of sharpening stones. Thankfully, finding a serviceable option is quite easy once you know the important features to look for.

What to Consider

There are a few important specifics you should consider when searching for a sharpening stone:

  • Grit: Arguably the most important aspect of your sharpening stone, grit is something that really determines the sharpening power of your stone. You’ll see this broken down into numbers to reflect the size of the grit, with the lower numbers marking courser stones for heavy-duty sharpening, and higher numbers for refining and polishing.
  • Size: Size hardly matters in regards to sharpening stones. However, the ideal size is dependent on the size of the knives you’ll be sharpening. Deciphering this is simple: the larger the knives, the larger the stone.
  • Type: You’ll find that whetstones are offered in many different types of materials. The most common include diamond, ceramic, natural, and synthetic (corundum).
  • Lubricant: No matter what type of stone you decide on, all sharpening stones require a lubricating substance to sharpen knives properly. You’ll have a choice between two:
    • Water: Water stones are a fantastic option for beginners and experienced sharpeners alike as they’re easy to use and easy to keep clean. Japanese water stones, diamond, and ceramic stones fall under this category.
    • Oil: A stone that has been spruced up with oil tends to hold its flatness more effectively in order to provide you with a sturdy sharpening surface. Some natural whetstones like India or Arkansas stones should be oiled instead because they are typically pre-bathed in oil on arrival. It’s important to remember that once you’ve used oil on a sharpening stone, you must continue to do so as water becomes ineffective after oil has been applied.
