10 Best Sharpening Stones in 2021

Buying a new tool or knife every time your blade becomes blunt is not a wise option at all. Instead, hone the blade. Sharpening stones are available in a variety of shapes, sizes, and material compositions, depending upon the tool whose blade is to be stropped. The finishing on the sharpened surface is reliant on the spatial density of the stone particles. 

Stropping tools/knives using the sharpening stone is not much of a hassle. There are several stones available in the market for serving the purpose. Which one will be best for you? Let’s find out.

To start with, we have the winners of three specific categories – overall performance, budget-friendly, and premium sharpness.

The finishing is way above average and too good for this price point. It gives a premium sharpness to your knives and your blades.

The stone comes with dimensions 7.25” x 2.25” x 1” and weighs 2.12 lbs (~ 962 g).

Sharpening Stone Buying Guide

Buying a sharpening stone can be a tedious task. You must pay attention to all the specifications of a stone before buying it. For selecting the best sharpening stone, various parameters are to be considered. Let’s have a look at the primary parameters!

Grit number / Stone grade

There are many ways of defining the quality of a whetstone. The most used ways are grit number and stone grade.

If the grit number is higher, it means a finer abrasive. This type basically provides finishes that are much smoother. Lower grit numbers, on the other hand, signify coarser abrasives. That is the ones that are responsible for scraping off materials much quicker.

Some stones are classified using grades. There are four grades – Soft, Hard, Translucent, and Black. Each grade is based on the density or the specific gravity of the mineral.

Size and Weight

The size and weight of the product should always be considered. If you need a stone for your camping needs, you should get one around 3” long. If you need a stone for your household or workplace, you should buy a 7” stone. The stone should be handy and convenient to carry.

Usability

The tools that a stone can sharpen should always match your requirements. The stone suitable for an ax may not be suitable for a knife, but there are stones that work effectively on almost all tools. Find the stone that perfectly fits your needs.

Accessories

The accessories that come in a whetstone kit might be very helpful for you. If you’re a beginner, you should look for a stone that comes with a manual. If you want perfect angles, you should definitely have an angle guide included in the stone. Whereas, if you want to give your knives a premium shine, look for a leather strop in the kit.

Material

The material of the stone is very crucial. If you choose the wrong stone, you might end up not using it ever. There are some natural stones that show radioactive nature. If you work at a place where this could cause problems, you need to look for it. There are some stones that degrade in water. If this could be challenging for you, look for this as well.

Summing up

Having a sharpening stone not only saves you from this hassle but also gives your knives an industry-grade shine. Choosing the right whetstone can be a task, but we have made it simple for you. Pick the one that best suits your needs!
