Best Whetstone Buying Guide
When you want to buy the best whetstone, you have to keep a few things in mind. Doing so will help ensure that you get the best product for all of your gardening tools, from your small scissors to your lawn mower blades. You can get natural or synthetic whetstones, and this short guide will help highlight the important considerations you want to keep in mind.
The best whetstones come with two or three grits, and this is usually one grit a side or one grit per whetstone. If you wanted to sharpen the blade of one of your garden tools but it has chipped edges, you’ll want a grit of 1,000 or lower. If you need to repair a dull blade, get a grit that is between 1,000 and 3,000. For refining your blade’s edge or finishing it, you’ll need a 4,000 to 8,000 grit. These grits refer to how coarse the surface of your best whetstone is, and it’ll play a huge role on how the finished blade turns out.
Whetstones work well for sharpening straight razors or knives, but you can easily use them on almost any bladed tool you have.
The grit will determine the stone type on your best whetstone. Luckily, you can break it down into three broad categories so it’s not so confusing. They include:
- Coarse – The coarse stones are less than 1,000 grit, and they work well for blades that have chips along the edges because it helps remove them. If you have a lawn edger with a chip, you can use it to bring it back to a like new state. This stone is also very nice for bringing an edge to very sharp blades, but you shouldn’t use them for normal sharpening because they’re too abrasive.
- Medium – Medium stones have a grit that ranges between 1,000 and 3,000. You’d use this stone if your knife isn’t damaged but it has lost the original sharp edge. You shouldn’t use this stone a lot because it can wear down your blade, but if you need to use a medium stone more often go for a 1,000 to 3,000 grit. They won’t sharpen, but they’ll help your blade retain the edge.
- Finishing – The bridge between a sharpening and finishing stone is 4,000 to 5,000 grit. These give you a very refined edge, and 5,000 is usually as far as you need to go. You can try a 6,000 or 8,000 grit stone, but do so sparingly so you don’t damage your edge.
The size of your best whetstone is very important because it won’t do a good job on your blade edge if it’s too small. Likewise, it can be awkward to sharpen smaller blades on a big whetstone. Blades are generally easier to sharpen on longer stones. A six-inch stone is a small model, an eight-inch stone is a very popular larger size, but a stone over eight-inches is considered generously sized. Three and four-inch stones are great for slipping into your pocket, but they’re not ideal for routinely sharpening any of your gardening gifts. For beginners, try for a six-inch stone until you get the hang of it and size up or down from there.
Think about the size of the different garden tools you have to sharpen on your whetstone. This will help give you a good idea on the size you need to keep everything you use sharp and ready.
Your budget will play a role to a point when it comes to picking out the best whetstone, but high-quality ones are usually under $100. To start, I recommend buying an inexpensive one to practice on until you get the hang of sharpening your blades. You can go to more expensive ones once you learn what you’re doing so you don’t accidentally damage it.
Picking out the best whetstone doesn’t have to be a huge challenge, and I’ve picked out 10 great choices for you. You can take a look and see which one looks like it’ll fit all of your requirements and sharpen all of your lawn tools. The buying guide lays out the basics of these whetstones, and you can use it to compare the products and make your final choice.
