You never need to worry about using the wrong stage to sharpen your knife. Both stage 1 and 2 use 100% diamond abrasives disks to sharpen and hone.
At this time, you may ask when you should use stage 3? In stage 3, it will use the stropping/polishing disk to polish the edge of your knife to make it super sharp and microscopically flawless polished edge. That mean stage 3 is the last step.
If you want to sharpen the serrated knives, you just need to sharpen it at stage 3 without stage 1 and 2.
Normally, all kinds of knives can be sharpened by this unit such as sports, kitchen, pocket, serrated knives, American style, European style, Asian style, and Japanese style.
Therefore, don’t use it to sharpen scissors, ax blade, or any other blades that can not fit in the slots. Otherwise, the slots may be damaged.

With the benefit of the adjustable sharpening guide and the variable speed motor, you can sharpen all your knives, tools, and anything with cutting edge.
The main advantage of using an abrasive belt to sharpen your knife because it can create a superior convex grind on a blade. The abrasive disk only creates a flat bevel on a blade that is thicker. The friction will also increase when cutting.
Comparatively, the abrasive belt creates a stronger blade that will cut better than the abrasive disk.
Presto 08800 EverSharp Electric Knife Sharpener
This is the 2-stage sharpening system. It can only work for non-serrated blades. But, if your serrated knives only have one side serrated, it can still be sharpened by this machine.

It features 3 suction cups on the bottom than can secure your machine on your countertop firmly so you can sharpen your knife in the most stable environment.
If the sharpening is dirty, clean it with a damp cloth only. Don’t immerse it in the water.

When you see the product image, I think you should know this is a 3-stage sharpening system that totally has 6 slots.
In the machine, other than the on/off switch, it also comes with the adjustable blade guides. It’s used to adjust the space between each slot to provide the optimum sharpening angles for your knives. It works perfectly for thick, medium, and thin knives.
Every time you sharpen must be from stage 1 to stage 3, that is from left to right. Stage 1 is for coarse grinding, stage 2 for precision grinding, and stage 3 for fine honing/polishing.
The operation is very simple. Turn on the machine. Just simply place your knives into the slot and adjust the blade guides. It can not simple anymore.

After sharpening, don’t use the knife to slice the food. Wash the knife or wipe it with a damp cloth to remove the filings from the sharpening process.
If you are sharpening the knives with high carbon content, the sharpening process may spark when the knives contact with the wheel. Don’t be afraid because it’s a normal phenomenon.
For safety, never left the knife sharpener unattended.

If you forget which side to start, just look at the numbers marked on the machine. It should have the number “1” and “2” on each side. Just simply follow the number.
It comes with a 3.5 feet cord for you to use conveniently on your kitchen without the need to use any cord extension.
The non-slip suction cup feet always secure your machine in place during the operation.
When you are sharpening the knife, remember don’t “saw” it back and forth on the slot. You just need to pull it back towards you.
At the same time, don’t apply any downward pressure to the knife. Just let the gravity and the weight of the knife do the work for you.
After sharpening, better wash it under the water to remove the filings on the blade. I think no one wants to eat metal. It must not tasty.
The receptacles that used to collect the metal filings should be emptied regularly.
The machine body can be clean by a damp cloth or dry towel only. Don’t wash it by water or place it near the water source.
Chef’sChoice 250 Diamond Hone Hybrid Sharpener Combines Electric and Manual Sharpening

It’s a 3-stage knife sharpener. Stage 1 and 2 is the ELECTRIC sharpening that uses a 100% diamond abrasive to sharpen your knife. But stage 3 is a MANUAL honing that uses ultra-fine diamond abrasive for the super sharp and polished edge.
Stage 3 of this model has a little bit different from other models. After the honing process, it will produce an arch-shaped edge of your knife that is much stronger and durable than traditional V-shaped and hollow ground edges.
The principle is 3-stage in this sharpener will create a triple-bevel edge. Each stage will sharpen at a slightly larger angle than the previous stage. In the end, it forms the arch-shaped edge.
It sounds good, right? But you have to do this manually.
It will work well with all 20-degree class knives such as the fine edge and serrated. Actually, you can use it to sharpen anything with cutting edge that fits the slots. According to the manual, it can also sharpen 15-degree knives.
But, don’t use it to sharpen any single-sided knives because it will sharpen both sides of the cutting edge simultaneously in stage 3. Pay attention to this if you have a traditional sashimi styled blade or any knives with the single-sided blade.
GA Knife Sharpener Electric – Sharpening Machine for Knives, Scissors, Screwdrivers
It’s a multipurpose model that’s not only able to sharpen your knives but also can sharpen your scissors, and screwdrivers. Therefore, it’s a 3-in-1 model.
If you want to sharpen your knives, it just needs 2-stage. On the top, you will see the “COARSE” on the left and “FINE” on the right. “COARSE” is stage 1 and “FINE” is stage 2.
In stage 1, it will reshape the angle. In stage 2, it’s engineered to both hone and polish simultaneously.
Note. This model is only able to sharpen the STRAIGHT BLADE but no SERRATED KNIVES. Don’t mix it up. Otherwise, it will damage your knives and the machine.
On the side, you will see “SCREWDRIVERS” and “SCISSORS”. If you want to sharpen your screwdrivers, just insert it to the hole just next to “SCREWDRIVERS”. The slot uses to sharpen the scissors is right under the hole. I think this foolproof design ensures you will not have any problems to sharpen your tools.
On the bottom, it comes with suction feet that can secure your machine firmly on your table. Without that, I think your machine will move around your table if you are sharpening the screwdrivers or scissors on the side.

Pay attention to the sharpening time, it can’t work for more than 3 minutes.

It’s not like the same brand’s model in the above. This model has to be used on the table. It doesn’t come with the handle so you can’t use it freehand to sharpen large blades.
In the front, you will see 2 fixed sharpening guides on both sides. You can sharpen anything with cutting edge that can put into the guides. In the right-hand side, it comes with a honing guide.

One thing needs to pay more attention. This model says it can sharpen the serrated knife. IN FACT, it uses the honing rod to sharpen but not the abrasive belt to sharpen. That means it has to be sharpened by your hand.
It’s a combo knife sharpener that combines electric and manual sharpening. Therefore, this model is also cheaper.
If you want a fully electric operated model, you have to choose Work Sharp Knife & Tool Sharpener and Work Sharp Knife & Tool Sharpener Ken Onion Edition that I have introduced in the beginning.
