10 Best Whetstones 2025 in the UK

The SHARPAL 162N Diamond Whetstone is designed for those seeking a reliable, quick, and durable sharpening solution. It's a dual grit whetstone with coarse grit of 325 for setting edges quickly and extra fine 1200 grit for a smooth finish. The use of industrial-grade monocrystalline diamonds ensures that it sharpens faster than traditional oil or water stones. This makes it particularly appealing for users who frequently sharpen hard materials like high-speed steel and ceramics without the need for water or oil, eliminating mess.

A notable feature is the SHARPAL's MirrorFlat technology, which maintains a flat surface over time, unlike traditional whetstones that can wear unevenly. This ensures consistent contact with the blade, enhancing the sharpening experience. The whetstone comes with a handy storage box that doubles as a non-slip base, and an angle guide that accommodates four different sharpening angles, supporting users in achieving the desired edge with ease.

However, the whetstone's diamond surface might be too aggressive for very fine knives, potentially leading to quick wear if not used carefully. At 1.4 kilograms, it is relatively heavy, which might make it less portable. Also, it is more expensive upfront compared to traditional stones. Despite these drawbacks, its durability and efficiency might justify the investment for frequent users or professionals who need a fast sharpening process.

The SHARPAL 162N Diamond Whetstone is best suited for DIY enthusiasts, hobbyists, and professionals looking for a robust and efficient sharpening tool.
