This patented advanced technology electric sharpener can repair

 After confirming that my equipment was out of warranty (more than a year), customer service informed me that the company does not accept devices for repairs or replacement parts "due to Covid." In addition, because they do not send out internal parts to consumers, they will not send you new discs to replace them yourself.   No, as others have mentioned, there are several models of the ChefChoice Electric Knife Sharpener. This Trizor XV 15 sharpener only provides a 15-degree edge. If you need or want a sharpener that can handle both 15 and 20 degree blades, the Chef'sChoice 1520 AngleSelect Diamond Hone Professional Electric Knife Sharpener for 15 & 20 Degree blades is the model to consider. I have incredibly good knives for all of the cooking I do, but they are not on par with some people's insanely expensive ($300+) chef knives. I wouldn't decrease a 20-degree knife to a 15-degree blade if I had them! However, because my blades are not of historic grade and the majority of professional knives on the market now have 15 degree edges, I used this sharpener to sharpen all of my knives to a 15 degree edge. Excellent outcomes!
I only have one Heckels knife and none from Shun. I do own a few Victorinox blades, including an 8" chef's knife with a 15° Asian edge grind rather than a 20° European/American edge. This sharpener's major wheels feature two distinct angles: 20° and 15°. The final honing wheel is designed to provide an extremely sharp edge to any edge angle. Unlike previous models, the honing wheel in use now is constructed of ceramic. On a Chef's Choice, I previously used a diamond honing wheel. The edge was decent, but not as sharp as what the ceramic wheel on the 1520 could produce. It's almost razor sharp. I give my 1520 five stars because I adore it.  I don't think this is the right instrument for the job. Use a wet stone grinder or something meant to remove metal to finish sharpening the blade, which it does rather nicely.  However, because the blade is so short, the wheel will not begin at the hilt. It's not a big deal. Furthermore, because you are changing the angle of the grind, it will take more than a few passes to accomplish. It will need some time and materials. I thought the end result was worthwhile! I wish you luck and keep you safe!  There are no "three sharpenings," as you claim. I recently realized it's not what I thought it was when I initially got it. For many years, I've had a vintage Chef's choice 2-slot. The older one is "OK," but not exceptional. It has two empty places. Fine and coarse, respectively. I bought it thinking it had three sharpening slots (one for coarse, one for fine, and one for honing) and a button to change the angle from 15 to 20 degrees. Only positions 1 and 3 are reserved for Asians, whereas slots 2 and 3 are reserved for Westerners. Because it just has "Coarse" and "Hone," it is essentially a 2-slot sharpener that isn't even as good as my 10-year-old one. I should have bought a genuine 3-slot for 15-degree knives.
Because the angles of the blades are so dissimilar, scissors are rarely sharpened with knife sharpeners. Henslow makes a sharpener that sharpens both and is available on Amazon.  The new Chef's Choice 15 Trizor XV sharpener is another innovation from the world's leading manufacturer of high-quality knife sharpeners. With the help of cutting-edge, unique flexible spring guides for exact adjustment of the sharpening angle, use the Trizor XV Edge easily for optimum sharpness and effortless cutting. Using ultra-sharp EdgeSelect technology and the stability of a triple-bevel (Trizor) edge, you can sharpen your knives to a high-performance 15-degree angle. The three-stage process and effective flexible stropping discs can sharpen the edges of fine knives while losing very little metal.At the same time, stage 1 conical discs with diamond abrasives create very small micro-grooves (for greater bite) and the first substantial bevel of the arch-shaped edge. Stage 2 uses finer diamond abrasives on conical discs to form the second, smaller bevel with finer microgrooves. In Stage 3, the unique flexible abrasive stropping disc process produces a microscopically perfect, sharp edge.
This patented advanced technology electric sharpener can repair and recreate the 20-degree edge for classic European and American-style knives, as well as the 15-degree edge for Asian-style knives and modern European and American-style knives. The Chef's Choice 1520 quickly and easily sharpens virtually all high-quality cutlery, including kitchen knives with American, European, or Asian styles, serrated or fine-edged blades, Santoku and traditional Japanese single-bevel edges, sports knives, and pocket knives. It takes around a minute to sharpen a knife for the first time. It takes roughly 10 seconds to resharpen. Precision angle guides ensure that the entire edge is sharpened precisely and eliminate all uncertainty. Use a conventional 20-degree edge or a sharper 15-degree edge for precision slicing. Diamond-only abrasives are used for honing and sharpening. serrated and straight-edge knives are sharpened. MOST KNIVES HAVE BEEN SHARPENED. 15-degree edging: This electric sharpener easily converts 20-degree knives to a finer 15-degree edge for faster cutting, leaving 15-degree blades razor sharp. EdgeSelect knife sharpening system's first and second stages use only 100% diamond abrasives to sharpen and polish the edges. Stage 3 involves polishing and finishing the blade using special stropping discs. The knife sharpener is simple to operate with an on/off button. Sharpening takes around one minute the first time and ten seconds the second time. the full length of the borderWhile in operation, flexible spring guides hold the blade at the proper angle, resulting in longer-lasting, arch-shaped edges down the whole blade.
