10 Best Sharpening Whetstones

The SHARPAL 162N Diamond Sharpening Stone stands out as a fast and durable option for sharpening knives and tools. It features two grit levels: a coarse 325 grit side for quickly fixing dull edges, and a finer 1200 grit side for polishing and honing. This dual grit setup covers most sharpening needs, from rough reshaping to finishing touches. Made with electroplated monocrystalline diamonds on a thick steel base, it sharpens much faster than traditional water or oil stones and stays flat over time, which helps maintain consistent sharpening results. Unlike many stones, this one works dry—no soaking or oil required—making it convenient and less messy to use.

The size (about 8 by 3 inches) is comfortable to handle and fits well in the included storage case with a non-slip base for stability. The package also includes a helpful angle guide with common sharpening angles, great for users unfamiliar with proper blade angles. Weighing 1.4 kilograms, it feels solid and stable on the countertop. Because it’s a diamond stone, it may be a bit more aggressive than water stones, which could remove metal faster if not careful. While the 1200 grit side is good for honing, it’s not as fine as very high-end stones that offer ultra-polished edges for special knives.

This product suits home cooks and hobbyists who want a reliable, low-maintenance sharpener that handles a variety of blade materials, including hard steels and ceramics. Its strong build, ease of use, and included accessories make it an excellent all-around stone for everyday sharpening tasks.

The SHARPAL 156N is a double-sided diamond sharpening stone designed for quick and effective knife sharpening. It offers two grit levels: a coarse 325 grit side for fast edge setting and an extra fine 1200 grit side for honing and polishing. This means you can handle both dull knives and fine touch-ups with one stone. Made with industrial monocrystalline diamonds electroplated on a steel base, it stands out for durability and speed, sharpening up to five times faster than traditional oil or water stones.

The stone doesn’t require soaking or oiling, which keeps the process clean and convenient, making it ideal for users who want a low-maintenance tool. Its size (6 inches by 2.5 inches) is practical for most kitchen knives, and the included non-slip rubber base offers stability during use, which is great for safety and control. The sharpening angle guide with preset angles helps beginners achieve consistent results without guesswork. One standout feature is the flatness guaranteed by their MirrorFlat technology, meaning the stone will maintain an even surface over time, avoiding common issues like uneven wear.

Since it's a diamond stone, it may feel rougher on delicate blades compared to water stones, and some users might miss the traditional soaking ritual that provides a smoother sharpening experience. Also, while it covers many blade materials including ceramic and carbide, those with very large or specialty knives might find the stone's length a bit limiting. This stone suits cooks and hobbyists who want a fast, durable, and easy-to-use sharpener with minimal fuss and reliable results.

The Sharp Pebble Premium Whetstone is a solid choice for anyone wanting to keep their knives sharp with minimal fuss. It features two grit levels—1000 for sharpening dull edges and 6000 for refining and polishing blades—covering basic to advanced sharpening needs well. Made from corundum (a form of aluminum oxide), it offers durable and effective abrasion that’s common in good whetstones. The stone’s size is compact (about 18 by 6 by 2.5 cm), making it easy to handle and store, though users with very large knives might find it a bit small for wide blades.

This waterstone requires soaking before use, which helps achieve smooth sharpening but means you need to set aside extra time to soak and maintain moisture during sharpening. The included non-slip bamboo base and rubber insert keep the stone stable, adding safety and comfort, especially for beginners. Also, the angle guide is a helpful tool for maintaining the correct sharpening angle, which can be tricky for those new to whetstones.

The stone is imported from China, and the kit includes useful extras like an instruction manual and eBook. It is user-friendly and versatile, making it suitable for home cooks, hobbyists, or professional chefs looking for a straightforward whetstone setup without needing expensive oils or complex maintenance.
