Dalmore Blue is a fairly dense and hard Scottish sandstone that has long been used for the needs of sharpening cutting tools. Like any sandstone, Dalmore Blue produces little to no slurry when working, but is an ideal lapping platform for slurrying other rock minerals that are used in sharpening, as well as for applying ready-made slurries (for example, slurry from HLAD’s). Dalmore Blue is fast and aggressive. In terms of abrasive ability, Dalmore Blue stone occupies a niche in the sharpening field, which has a rather small range of possible offers in natural abrasives. It is an excellent stone for transitioning from base 1000 grit bars to pre-finish abrasives (equivalent to 8000 grit in JIS), such as Dalmore Blue's fellow countryman Tam O'Shanter Shale. Dalmore Blue - Like most Welsh and Scottish sharpening stones, it performs well on steels of a wide range of hardnesses and compositions. As a coolant, when working with a Dalmore Blue grinding stone, both water and oil can be used. Alignment on silicon carbide powder for this stone is recommended to be completed on the F320 fraction.
