Natural Stone Whetstone
The Gränsfors Natural Stone Whetstone consists of two unique natural materials that have been selected to best meet the need for both coarse and fine grinding.
The coarser side consists of a sandstone from Orsa with a grain size of between 120 and 200 grit. The sandstone is a fossil-free, sedimentary type of rock that consists mostly of silica-bonded quartz. Sandstone has been used as a grinding stone since the 16th century, and with its coarser, slightly porous surface it offers good qualities to restore the edge to its original bevel face phase and sharpness before it needs to be sharpened again.
The fine side of the whetstone consists of a fine-grained clay slate from Los, which is a unique material found only in Los and has been used as a whetstone since the end of the 19th century. The Los stone has a grain size of between 500 and 1,000 grit and has a smooth, hard surface. With its smooth, fine-grained surface, the Los stone provides good qualities to create a keen edge with good sharpness and bite.
The whetstone’s design makes it very user-friendly as it is easy to get a good grip, which makes it relatively easy to sharpen its current edge by following the existing bevel face and grinding angle. The whetstone is supplied with a sheath made of vegetable tanned leather from Tärnsjö with a small eyelet so that you can easily attach the whetstone to your trousers or rucksack, ideal if you want to take it with you into the forest or countryside.
The sheath can also be used with some caution to give the edge a final strop to achieve perfect sharpness.
The product can be purchased in Gränsfors Bruks factory shop and at selected retailers.
