- All oil stones, natural or synthetic, are porous in natures. The presence
of oil on the surface is required to keep the pores open, thereby permitting
the stone to work effectively to suspend metal and abrasive particles
from the stone’s cutting surface. Oil applies to the surface is,
however absorbed into the stone and tends to pass out the underside.
To offset this absorption, these oil stones are pre-filled with an oil
at the factory. This exclusive quality feature retards loading, saves
time, and eliminated the necessity of pre-soaking the stone prior to
- Manmade/Synthetic Stones are manufacturer with abrasives graded to
a consistent particle side, blended with selected bonding agents, molded
to shape, and finished to exacting surface configurations.
- Crystolon stones, manufacturer with silicone carbide abrasives,
are the best choice for quick sharpening where the speed in producing
the edge is more important than the fineness of the cutting edge. Grey
in color. Available in coarse, medium and fine grits.
- India Stones are quarried from the finest Ozark novaculite
( silicon quartz) deposits, precision sawn to size, and finished to
exacting surface configurations. Although there are no industry established
standards for classifying hardness, particle size, or color of natural
stones, the standards established by Norton nearly 100 years ago are
accepted by most knowledgeable sources as industry standards. However,
all suppliers do not adhere to these standards, some choosing to classify
and label sharpening stones at their own discretion. This has resulted
in much confusion for users, who experience widely varying performance
levels between similarly identified stones of different manufactures.
Norton guarantees a given product will duplicate performance stone after
stone. For this reason, we have trademarked the Norton Arkansas Stones
as a guarantee of Norton quality and performance. When sharpening, these
Arkansas stone do not remove as much metal as man-made stones; hence
tools and knives last significantly longer. Due to their unique crystalline
structure, Arkansas stone polish as they sharpen, imparting a keen,
- Norton Hard Translucent Arkansas (ultra fine) stones are
the finest grained and most dense natural stone available. Used to produce
the keenest, most precise finish possible. They impart polished, razor-like
edged. Translucent white in its purest form, hard translucent Arkansas
may contain shades of red, yellow and grey. Translucent stones are named
due to their ability to let light pass through.
- Norton Hard Arkansas (superfine) stones are coarser and less
dense than hard Arkansas stones. Used for imparting the finest edges
necessary for most cutting tools and knives. Opaque milky white in color.
- Norton Soft Arkansas (extra fine) stones are the coarsest-grained
and least dense of the natural stones. Used primarily to sharpen and
upgrade tool and knife edged to an even, polished surface, frequently
after sharpening with synthetic stones. Opaque milky white in color.
