Product Description
-------------------
The Norton Crystolon and India IM313 11-1/2 inch three-stone
sharpening system includes 100-grit and 150-grit silicon carbide
stones and a 320-grit aluminum oxide stone, a self-contained
three-stone bench sharpening unit with a lid and no-slip rubber
feet, a reservoir, an angle guide, and a 16 oz. bottle of
sharpening stone oil for lubrication. In the top of the bench
sharpening unit, a rotating axis holds the stones firmly in
place, protecting them against breakage, and bringing the desired
stone into position for sharpening. The base of the sharpening
unit is a reservoir that allows submersion of the unused stones,
keeping them clean and saturated. The angle guide helps to
position a tool correctly for sharpening. The three stones in
this system are used sequentially to restore cutting edges on
straight-edged tools, such as knives, chisels, plane blades, and
precision instruments; the 100-grit silicon carbide stone is
suitable for repairing a cutting edge, while the 150-grit silicon
carbide stone is suitable for sharpening and maintaining the
edge, and the 320-grit aluminum oxide stone produces a honed
cutting edge.
The sharpening stone oil meets FDA requirements for use near
food, and consists of copeia-grade mineral oil formulated
with the correct lubricity for oilstone sharpening. It prevents
metal from bonding with the abrasive surface by flushing away
dislodged abrasive and metal chips. Each stone is also prefilled
with oil to save time and eliminate the need to presoak it prior
to use. The silicon carbide stones are fast-cutting and offer
effective sharpening, even under light pressure. The aluminum
oxide stone has a tough fracture- and wear-resistant grit that is
more durable than silicon carbide and capable of sharpening to
very close tolerances.
Each stone is created by grading the material to a consistent
particle size and blending it with bonding agents. It is then
molded and surface-finished. These unusually large 1/2 x 11-1/2 x
2-1/2 inch (H x W x D) oilstones, which are suitable for bench
use, are harder and more durable than a waterstone. (H is height,
the vertical distance from lowest to highest point; W is width,
the horizontal distance from left to right; D is depth, the
horizontal distance from front to back.) They conform to the
American National Standards Institute (ANSI) abrasive grit
standard.
Sharpening stones, or whetstones, are abrasive surfaces used to
sharpen and hone the edges of steel cutting implements, such as
chisels, knives, scissors, hand scrapers, and plane blades.
Sharpening is the process of creating or re-establishing a
cutting edge by grinding away portions of the metal to adjust the
angle of the edge and reform the shape. Honing removes small
imperfections. Stones can be flat, for working flat edges, or
shaped, for edges that are more complex. Sharpening stones are
made of natural or synthetic materials that range from softer to
harder, and are categorized by the size of their abrasive
particles, known as grit. A stone with a coarser grit is used
when more metal needs to be removed (e.g., when sharpening a
nicked or very dull blade); the stone with the finest grit
produces the sharpest edge. Where numbers are assigned to specify
grit, they range from coarser grit (low) to finer grit (high).
Some sharpening stones are designed for use with a lubricating
liquid, some can be used dry, and others can be used either wet
or dry. When used with lubricating liquid, a sharpening stone can
be called a waterstone or an oilstone, based on the lubricant
required.

---------------------
The IM313 sharpening system has long been considered the to be
the ultimate sharpening system. The 2-1/2 In wide x 11-1/2 In.
long stone permits long strokes for faster more precise
sharpening of all straight edge tools. The coarse Crystalon®
stone quickly restores badly worn cutting edges; the medium
Crystalon® stone produces the average edge needed for many tools
and the fine India® stone hones to a sharper edge. The heavy base
has a non skid bottom. A pint can of Norton Oil is included with
each IM313
