The Shapton K0705#12000 Finish Cream is a high-grit whetstone, making it ideal for achieving a fine, polished edge on knives and tools. With a grit size of #12000, it offers exceptional polishing ability, perfect for those looking to get a mirror-like finish on their blades.

The stone's dimensions are 8.3 x 2.8 x 0.6 inches, providing a substantial surface area for sharpening tasks while remaining compact and easy to store. The material used is a high-quality whetstone that ensures durability and effective sharpening performance. One of the key advantages of this product is its minimal soaking time, allowing users to quickly get to work without lengthy preparation.

Maintenance is straightforward, as the stone does not require complex care, making it suitable for users of all experience levels. Its high grit size means it is best used for finishing touches rather than initial sharpening, which might require a coarser stone. Additionally, its relatively thin profile might not be as durable over extended use compared to thicker stones. The product is lightweight at 1.1 pounds (500 grams), making it easy to handle. This whetstone is a great choice for users who need a finishing stone to achieve a sharp, polished edge on their tools.

The SHAPTON Ha No Kuromaku Ceramic Whetstone set offers two stones with different grit sizes: a Medium Grit (#1000) for general sharpening and a Fine Grit (#5000) for finishing touches. This makes it versatile for various sharpening needs, from kitchen knives to precision tools and sushi knives. The ceramic material ensures durability and effective sharpening. The stones come with ventilated plastic boxes that double as stone holders, which is convenient for storage and use. Each stone measures 8-1/4 x 2-3/4 x 1/2 inches, providing a good working surface for most sharpening tasks.

A significant advantage of these stones is their minimal soaking time – unlike traditional Japanese water stones that require prolonged soaking, these stones are ready to use with just a quick splash of water. Maintenance is also straightforward, as ceramic stones generally do not wear down quickly and can be easily cleaned. However, the set might be on the pricier side compared to other options, and the medium grit stone serves a dual purpose as a coarse grit, which may not be ideal for those needing a dedicated coarse stone.

The variety of available colors is a nice touch for those who appreciate aesthetic choices. Despite the higher price, this whetstone set is a solid choice for anyone looking for a reliable and efficient sharpening solution.

The Shapton Glass Stone 16000 Grit 5mm is an ultra-fine sharpening stone designed for those looking to achieve a razor-sharp edge on their tools and knives. With a grit size of 16000, it is best suited for final polishing and achieving a mirror finish. The stone is made of corundum, known for its durability and effective sharpening capability. Its dimensions are 8.5 inches long, 3 inches wide, and just 0.85 inches thick, which makes it compact and easy to handle.

One of its standout features is the very high density and uniformity of the abrasive particles, ensuring consistent sharpening performance across the stone's surface. This consistency helps in maintaining precision during sharpening tasks. Unlike traditional water stones, the Shapton Glass Stone requires minimal soaking time, which saves you time and effort in preparation. However, it is still recommended to wet the stone before use to achieve the best results. Maintenance is relatively easy, although due to its high grit, proper care must be taken to avoid clogging and to ensure longevity.

One potential downside is its thinness (5mm), which may wear out faster compared to thicker stones, especially with frequent use. Additionally, being an international product, it may come with labeling or instruction differences, which could be a minor inconvenience for some users. This stone is particularly suitable for those who need precision and fine polishing in their sharpening tasks, such as professional chefs or woodworking enthusiasts.
