Review SUNNEN Portable Hone Extra Stones And Parts

The Sunnen JN90 Hone Stones are a premium set of honing stones designed for use with kitchen knives. These stones are made of high-quality Aluminum Oxide, which is known for its durability and ability to produce a sharp and long-lasting edge.

The JN90 set includes three stones, each with a different grit size to facilitate the entire honing process. The first stone, which is the coarsest in the set, measures 120 grit. It is used for initial shaping and removing heavy scratches from the blade. The second stone, with a grit size of 400, is used for fine sharpening and refining the edge. The third and finest stone, which has a grit size of 1000, is used for polishing the edge and achieving a mirror-like finish.

The stones are flat and have a generous 12 x 3 inches size, which provides ample surface area for honing multiple knives at once. They also come with non-slip rubber bases that prevent them from moving around during use. The stones are easy to use and maintain, as they do not require any oil or water, and they can be used dry or with a honing solution.

The JN90 Hone Stones are an excellent investment for any home cook or professional chef who values the importance of a sharp and well-maintained knife collection. They offer a reliable and effective way to maintain the edge of your knives, ensuring that they remain in optimal condition for all your cutting needs. The stones are also easy to clean and store, making them a practical and convenient addition to any kitchen.
