Slurik is a bar for directing the suspension on the working surface of the grinding stone. Basically, the suspension is actively released during sharpening on various bars made from shale rocks. Accordingly, using a small piece of slate, it is possible to effectively induce a suspension both on a stone of the same breed and on other grinding stones (natural or synthetic), even on those that do not emit their own suspension, but at the same time perfectly allow you to work on a "foreign ", induced by red lead. Working on a suspension significantly increases the productivity of the sharpening process, makes it tactilely softer, a stone with a suspension begins to work in a completely different way. There are sharpening techniques, with the help of which, on one lapping platform (for example, made of fine-grained sandstone, which does not emit its own suspension and practically does not affect the result of processing the surface of the supply), the entire grinding cycle from peeling to finishing is carried out by sequentially changing , in the Japanese interpretation) of various grain sizes. Suspension, both from slurik and from the working surface of the stone, is knocked out when used as a coolant - water. Therefore, work with slurik must be carried out precisely with the use of water as a lubricating fluid.
Dragon's Tonque (DT) or Dragon's Tongue is a fairly common whetstone from the North Wales Shale family. Dragon's Tonque slate has been commercially mined since 1860 by Inigo Jones & Co's Tudor Slate Works in Groeslon at Carnarvon in the Aberllefenni quarry and Aberllefenni mines. Due to a fairly well-established production and marketing process, as well as sufficient reserves of the breed, Dragon's Tonque has become widespread as a whetstone, as well as a stone for finishing razors. Dragon's Tonque has a fairly wide range of possible colors (Red/Blue/Gray, as indicated in the guide) from light gray to dark gray, sometimes with a reddish or greenish tint due to impurities of various metal oxides. Most often, the color of Dragon's Tonque slate is closer to black, especially when wetted. Dragon's Tonque is quite dense and hard compared to other natural stones used for sharpening, its density is up to 2.8 grams per cubic centimeter. There are quite different data in the positioning of Dragon's Tonque slates in terms of abrasive ability - from 4000 to 10000 grit in comparison with the grit of synthetic abrasives. This sample of sluric has been tested and claimed to be 8000 grit. In operation, Dragon's Tonque gives a uniform scratch and higher material removal rate than most shale grades used in sharpening.

Slurik Dragon’s Tonque has dimensions of 52x30x10 mm, does not require pre-treatment or finishing and is completely ready for use.
