They qualify into five types:

Premium-Fine Grade:

Very fine, final finishing variety & uniquely clear, hard grain of stone.

Slowcutting stoneused in final finishing.

Note on Premium-Fine Grade:Extremelytight grain of stone.

For optimum finishing, use on surgical grade stainless steelalloys.

~ Rosetta Matrixare recommended for veryhard tempers. ~

Superior-Fine Grade:

Similarly, a very fine finishing type, equally as hard and durable, yet of slightly less tightness to the grain.

Regular-Fine Grade:

Excellent for procession honing, cuts quickly with a specific ease to control.

The grain is more open, has somewhat less density.

Provides stainless alloys with brilliant finishing polish.

Course Grade:

Agritty type of micro-quartz mineral, quite porous & fast cutting.

For resurfacing &/or removingsmall damages to the edge,initializing bevels, &c.

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. In specific lots, certain amounts of precious minerals at times occur as small, golden flecks seen in the cross section. This aspect demonstrates both the level of geothermic activity that had once taken place and the actual qualities of their Mukovite 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.
In one respect, one could compare the natural sharpening stone, perhaps, with wild salmon. Farmed salmon, how so ever indispensable, cannot truly coverthe palate soclearly as their sea borne counterparts.This quality could also be likened to the comparison between enamel paint coatings and the so-called powder coat process. Powder coating is industrially regarded as the superior, the polymer being put through a high temperature oven thus to create a lasting, durable bond to the surface.
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.i.4About our company

For 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.
