'Slurry Stone Cost Inclusive'
For all edged tools requiring razor sharp, quality honing.
Use with fine mineral oil as available by region or clean water if oil is never given application.
~Very fine white slurry with application of 400-600 grit diamond plate or rubbing stone~
Microporous silica composes in the structural geometry leaving edges brilliance & durability.
Particles (i.e. slurry) allows both honing without clogging the pores as well as giving the highest polishing to the steel.
Microcrystalline particles release while honing create a more durable final polish than any type of synthetic stone.

~ All inquiries welcome ~RFACo. Note on Natural Sharpening Stones.A 'pure' sample of novaculite would contain SiO2 or molecular silica only. Our 'Invitica' listings are from this type of geological formation. Sedimentary or clay matrix novaculite often have 2/3 SiO2 [silicon dioxide] content. Generally speaking, this is the microporous form of quartzite doing the sharpening. The other 1/3 is a bonding mineral often known as either Muskovite or as Sericite.".The 'Persia' hones as fine examples of these sharpening stones. Black veins occurring in certain hones exhibit iron oxide concentrations in the Muskovite. In others, bluish patches demonstrate other mineralizations within the clay matrix stones. Iron oxide is normally present. Certain matrix stones have higher, more visible concentrations [In Japan, this characteristic is known as renge]. Examples of our “Lochinvar” sharpening stones demonstrate this ‘Iron Renge’ as an orange feathering or what specific examples surface as a pattern of glowing metallic sheen.“Wild Rose” ‘Premium-Fine', 'Superior-Fine', 'Regular-Fine', & 'Select’ stones have been exposed to very high temperature volcanic or geothermal activities, thus giving them giving them an extraordinary hardness. This aspect demonstrates both the level of geothermic activity that had once taken place and the actual qualities of their mineral sediment.Often, natural hones are praised because the actual particle fineness is superior to that of man-made and synthetic stone. Also, the natural particles break away while honing, in turn leading to both longer lasting and more durable edges. Also, the mineralogy of individual deposits lead to a greater range of specifics. Such honing creates subtle, distinguishing results, some are more 'crisp', some more 'feathered', certain stones finish well again with the steel of a certain temper, and so on. Lastly, it is within professional establishment that natural stones do, in fact, harden the edge.Sharpening-grade novaculite normally produces a range of textures. These range from those with the appearance of an unglazed porcelain, a porosity of several percent and serves as a good stone for coarse sharpening, to an extremely fine-grained material known for having almost no porosity and as an excellent tool for honing a razor-sharp blade.About our companyFor all types of fine stainless steel alloys, naturally occurring minerals possess many advantages. At Royal Flint Abrasives Co., mineral specimens specific to the Canadian West are selected for the manufacture and retail of sharpening stones. Quarried at the naturally occurring deposits and brought into local workshop facilities, RFACo. means to employ sustainable resources of the highest quality to achieve surpassing edges every time.
