underStandIng the model 312 ® 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 combina- tion 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”.

Unless you have special blades designed to be sharpened primarily on one side of the edge (such as Asian Kataba blades) you will want to sharpen equally in the right and left slots of each stage that you use. This will insure that the facets on each side of the edge are of equal size and that the edge will cut straight at all times.

® The Chef’sChoice Model 312 is designed to sharpen either Straight edge or Serrated edge blades. Follow these instructions for optimum results. proCedure for SharpenIng StraIght edge BladeS StraIght edge BladeS: SharpenIng fIrSt tIme Always clean the blade free of dirt, oil and food before inserting into sharpener. Before you turn on the power, slip a knife blade smoothly into the slot between the left angle guide of Stage 1 and the plastic spring.

Next, repeat with one full length pull in the right slot of Stage 1. (See Figure 4) Note: Each time you insert the blade, simultaneously pull the blade toward you. Never push the blade away from you. Apply just enough downward pressure to make contact with the disk – added pressure does not speed up the sharpening process.

Stage 2: In general only two pairs of slow pulls (about 4-6 seconds each) followed by two pairs of faster pulls (1-2 seconds each) in Stage 2 will be needed to obtain a razor sharp edge. Make alternating pulls in left and right slots (Figure 6). Fewer fast pulls in Stage 2 are preferable if you will be cutting fibrous foods as discussed in more detail in the following section.

proCedure for SharpenIng Serrated BladeS Serrated blades are similar to small saw blades with scalloped depressions and a series of pointed teeth. In normal use the points of the teeth do most of the cutting. ® Serrated blades of all types can be sharpened in the Chef’sChoice Model 312.

SuggeStIonS 1. Because of the ultra fine diamond abrasives used in this sharpener, it is extremely important to always clean all food, fat, and foreign materials from the knife before sharpening or resharpening. If knife is soiled, wash it thoroughly before sharpening. If food, oil or fats accumulate on the ultrafine diamonds of Stage 2 you will notice that it will sharpen more slowly.

8. Used correctly you will find you can sharpen the entire blade to within 1/8” of the bolster or ® handle. This is a major advantage of the Chef’sChoice Model 312 compared to conven- tional sharpening methods – especially important when sharpening chef’s knives where you need to sharpen the entire blade length in order to maintain the curvature of the edge line.
