Mercer Triple Diamond Electric Knife Sharpener

Mercer Triple Diamond Electric Knife Sharpener

Introducing the Mercer Triple Diamond knife sharpener. A three-stage sharpener able to handle both serrated and straight-edged blades. Made in the USA and NSF Certified. Be sure to read all instructions included. Always use a clean knife when sharpening. Before you turn on the power, be sure to remove the cover over stage one. Insert the knife into stage one on the left side starting with the heel end first. Drag the blade through at a rate of two inches per second. About four seconds for an 8” blade. Repeat the process on the right hand side of stage one. No matter what kind of blade you’re sharpening, whether it’s a straight-edge knife or a serrated blade, excessive pressure or twisting of the blade will not speed up or help the sharpening process. Stage one is generally used for knives that are extremely dull or have not been sharpened in a long time. If you are just maintaining the knife, and putting a quick edge back on, skip right to stage two. You will then repeat the process with stage two, left side first, same rate of speed, and then followed by the right hand side of stage two. Continue on to the strapping stage of stage three, a fine polymer disc takes the burr off the blade; gives it a razor sharp edge. Never submerge the M10000 knife sharpener into liquids, water, or cleaning solutions. A damp rag is all you need to clean the unit. The dressing tool on the front of the sharpener will clean the fine polymer disc in stage three. Unlike most knife sharpeners on the market, the M10000 uniquely sharpens serrated blades. Sharpening on serrated blades can be obtained by simply dragging the knife through the third stage slowly. Again, two inches per second. 5-10 sets of pulls through the third stage should bring back a razor sharp serrated knife. Bread knives, utility knives, and even steak knives can be sharpened on the M 10000. Repeat the process 5-10 times per side for serrated knives. If you’re in need of sharpening a damaged serrated knife, a quick pull through the left side of stage two, followed by a quick pull through the right hand side of stage 2, then moving along to stage 3, 5-10 sets of both the left and the right hand side on the fine polymer disc of stage 3 should bring back a razor sharp edge on a serrated blade. Cleaning the M10000 is as easy as pulling out the cartridge on the bottom and cleaning the magnet that collects the shavings. This can be done once a month. Mercer cutlery is here to help.

Many chefs like the convenience, speed, and results of an electric sharpener. With little to no pressure, pull the knife once through the left slot of stage one. Sharpen the entire blade length. For an 8" blade, each pull should take about 4 seconds. Pull shorter blades through in 2 – 3 seconds and longer blades in 6 seconds. Use the same procedure in stage two as is shown in stage one. Pull the blade once through the left slot of stage two and once through the right slot. In general, only one or two pairs of pulls in stage three will be necessary to obtain a razor sharp edge. As in stages one and two, make alternate pulls in left and right slots, pull the knife through the slots at the same speed used in stages one and two.

    We replaced a different brand with this knife sharpener and we are very happy with the ease of use and the sharpness of our knives. It is everything we expected and will purchase more for our other restaurants.

    This is something I should have bought years ago. Sharpens all knives perfectly. I have expensive knives I quit using because they were so dull. This sharpener has brought them back to life!
