DIAMOND ULTRAHONE SHARPENER
This unique Chef'sChoice® Diamond UltraHone® Sharpener is designed to sharpen knives
with either straight or serrated edges. This two (2) stage sharpener has two precision
sharpening/honing stages, one with fine and the other with ultrafine 100% diamond
abrasive. This combination can be used to create either an ultra sharp, smooth faceted
edge for effortless cutting and presentations or one with a selected amount of
residual "bite".
The sharpening and honing actions are controlled by using precisely angled guides for the
blade and precisely matched conically surfaced abrasive disks. The sharpening angle is
slightly larger in Stage 2 than in Stage 1. The sharpening rate is carefully controlled by the
size of diamonds used and by unique internal springs that limit the amount of pressure
that can be applied to the edge by the abrasive disks.
Fine diamond-coated conical disks in Stage 1 create microgrooves along the facets on
each side of the edge establishing the first angled bevel of the edge. In Stage 2 precision
disks coated with micron sized diamonds gently hone and polish the facets immediately
adjacent to the edge creating a microbevel along a microscopically thin straight and
polished edge. The honing action simultaneously polishes and sharpens the boundaries
of those microgrooves created by the diamond abrasives in Stage 1 adjacent to the edge
until they become sharp micro flutes that will assist the cutting action with "difficult to
cut" materials.
This unique two stage design gives you an extremely sharp edge and because of the
second angle microbevel, you will notice that your knives stay sharp longer than those
sharpened by conventional means.
The following sections describe the general procedures for optimal sharpening. One of
the important advantages of using the Model 323 is that you can hone and polish your
knives to razor sharp edges as often as needed and yet experience little knife wear
compared to older sharpening methods. Resharpening can commonly be done by using
just the gentle polishing action of Stage 2. (See Resharpening Section).
Each sharpening Stage is equipped with flexible plastic springs that are positioned over
the sharpening disks (see Figure 1) to hold the face of your knife securely against the
precision guides in the right and left slots of each stage during sharpening.
