How To Choose Electric Knife Sharpener – Buyer’s Guide

Here’s what you need to know before you decide to invest in an electric knife sharpening system:
  • Abrasive Surface – Diamonds are considered to be the hardest material, closely followed by polished ceramic and tungsten carbide. Grit is used to measure the abrasiveness of any sharpening unit, the higher it is the better and finer the abrasiveness of the tool will be. Anything between 1000-grit and 120-grit will get the job done for you.
  • Performance – The best sharpening tool is the one that is known for its performance, which is essentially its potential to create a consistently smooth, keen edge without any scratches.
  • Sharpening Stages – While coarse abrasive reshapes the blade edges, the finer abrasives polish and enhance its longevity. Investing in a sharpening machine with multiple stages for sharpening is therefore crucial.
  • Angle Guide – If the serrated electric knife sharpener features an adjustable, accurate angle guide; even the most inexperienced user can sharpen the blade at the right angle.
  • Safety – The sharpening machine should also be safe enough to be used for sharpening, especially because you’re dealing with potentially dangerous stuff like tools and knives. It is essential that this tool comes with added stability and rails so that any untoward incident can be avoided.

And finally, it would help you a great deal if the customer support and warranty period of the product is impressive, especially if it is a high-end model.

How To Use The Best Electric Knife Sharpener

The next thing that you should know about an electric knife sharpening machine is how to use it. As soon as you begin the process of blade sharpening, you need to make sure that you start with the coarse side and then move to the finer side. Follow these steps to get best results:
  • Step no.1- Place your knife blade in the provided slot. Make sure that the knife’s heel is pressed down so much so that it connects with the tool’s grinding stone. Begin with the knife heel and then slowly pull through to its tip.
  • Step no.2- Next, slide your knife through the machine’s slot. Make sure that the blade is angled between 15 and 20 degrees. The unit will set the knife handle automatically as it gets pulled through the machine slot to connect with the stone (grinding).
  • Step no.3- Pass the knife blade slowly through two times (each side). Generally, electric sharpening models are highly efficient, so two passes are sufficient for reshaping as well as sharpening the knife blade.
  • Step no.4- Repeat this process on the tool’s finer stones. Since your blade has already been reshaped by passing it through the coarse stone, you need to polish it by passing it two times through the finer grit.
  • Step no.5- Finally, you need to rinse your knife and then dry it.

How To Tell That It’s Time To Sharp The Knife

Using a dull knife for cutting is not only going to make your work more difficult, but it can also be dangerous to use a dull knife.

There is no warning signal to remind you that your knife needs sharpening, but the following signs can help you understand that it is time to get your knife sharpened:

  • The Dull Feeling

Familiarizing with the feel of the blade can be very helpful in understanding when it needs sharpening. You need to carefully and gently run the fingertips on the blade edge. If a knife is sharp, you will feel it, as the blade will feature a distinct, well-defined edge. Similarly, a blade that feels rounded or dull can be identified immediately on running the fingertips.

  • Paper Test

You can resort to a magazine page or standard paper (white) to find out whether your knife blade is sharp or dull. It is an easy and fast way to test the knife blade’s sharpness. Holding the white paper upright in one hand, you need to use your other hand to hold your knife exactly at the topmost edge of the paper to slice it downward. While a knife that is sharp will slice it in two pieces, a blunt one will rip it unevenly.

  • Tomato Smashing

Another great way to test if your knife is sharp or not is by observing the way it slices tomatoes. Clean slices of tomatoes are the end result of a sharp knife, but a blunt one with catch on the tomato skin.

Knife Blade Types

Another consideration that you need to make while looking for a sharpening tool is what kind of blade it can sharpen. For example, an electric ceramic knife sharpener is designed exclusively to chip away ceramics from a kitchen knife with ceramic blade. Similarly, electric knife sharpener for pocket knives are engineered to effectively sharpen such knives.

If you have already covered the top models mentioned above, you know that there are certain products that not only sharpen the blade of a knife, but also that of other tools like garden shears and scissors.

The electric knife and scissor sharpener is what you will need if you’re looking for a machine that can sharpen knives as well as other household tools like scissors. Not all knife sharpening units can sharpen serrated and straight knives alike as the slots are usually thinner.

An electric serrated knife sharpener generally comes with diamond abrasives and knife guides to sharpen serrated knives with precision. So, your choice of product should depend largely on the blade type. Read on to find out more about factors that affect your electric knife sharpening tool buying decision.

Sharpener Types 

By now it must clear to you that there are various types of electric knife sharpening tools in the market.

Electric belt knife sharpener is a pro multitool to sharpen any kind of appliances in your house.  It includes the delt that is highly accessible and all you kneed is to know the right blade angle.

Any professional electric knife sharpener with high performance generally works in different stages and features a belt that controls these stages or the multiple slots depending on the tool type.

Whether you are looking for an electric kitchen knife sharpener that has a straight blade or an electric hunting knife sharpener with serrated blade, you will need a machine with more than one stage sharpening process for best results.

The only way to keep professional knives sharp is by using them on an electric stage 2 knife sharpener or a 3 stage electric knife sharpener, both of which have the ability to effectively carry out the different stages of sharpening and honing the knife blade with degree accuracy and detail.

Most of the products mentioned above feature either 2-stage or 3-stage sharpening process so that your knife blade gets the most precise and razor-sharp edge possible.

Electric Knife Sharpener Vs Stone

Using a sharpening stone for your knife requires proper skills and experience in holding your knife at the accurate angle. Otherwise, you may end up spoiling the knife’s cutting edge.

Additionally, you have to use lubricants like water or mineral oil on certain stones prior to sharpening your knife. Doing so prevents the chances of ruining the stone’s capability to sharpen the blade.

However, when you use an electric sharpening machine like the Presto professional electric knife sharpener 08810, all you have to do is place the knife in the slot and switch on the machine. The guides in the machine ensure the accuracy of blade angle while sharpening, and some models feature magnetic pad to prevent the knife from spoiling the product’s performance. Moreover, electric sharpening units use diamond abrasives for sharpening, which are more aggressive than sharpening stones.

Electric Knife Sharpener Vs Manual Sharpener

A manual sharpening tool will require much effort on your part to sharpen the blade, as the entire sharpening process depends on how much effort you put in. Also, manual units come with a simple mechanism to perform only one function of sharpening the blade.

An electric sharpening machine, on the other hand, does not require you to put in much physical effort to sharpen the blade. Their operation is easy and simple, and they come with more functions and features compared to the manual ones, like an electric knife sharpener and can opener. Although these machines are a bit more expensive than the manual ones, they are worth the money you spend.

Homemade Electric Knife Sharpener

Want to know how you can make an electric knife sharpening unit at home?

This is something you won’t find in most electric knife sharpener reviews. The following lines describe how you can build an electric sharpening tool on your own without much difficulty. You can use this machine on different types of knives as well as tools at home.

Things You Will Need

  • 1 inch thick MDF
  • Buffing/Sharpening Compound
  • Hex-nuts (2)
  • Bolt
  • Washers (2, small)
  • Hardwood
  • Spray lubricant
  • Clamps
  • Hole Saw (89 mm, 3.5”)
  • A Drill-bit Set
  • File
  • Drill-Press
  • Drill
  • Woodworking Machine (6-in-1)
  • Safety Goggles, respirator and earmuff for safety

Preparation Time – 1 hour (approx.)

This homemade electric sharpening tool is fairly easy to build, and requires a minimum amount of investment.

  • Step no.1- With the help of your Hole Saw (89 mm), cut through the MDF in your Drill-Press. Make sure you clamp down the MDF tightly on your table as MDF is generally very heavy. Once drilling is over, you need to pop the lug out.
  • Step no.2- Assemble the woodworking machine on your bench grinder, and then clamp it on the table. Using this machine remove all those threads that lie close to the screw’s head portion. You can add water to the screw every now and then to avoid any airborne dust.
  • Step no.3- Measure the height from the table to the bolt (should be approximately 5 cm), and then drill a hole into the plywood scrap piece at 5 cm distance from the bottom portion.
  • Step no.4- Insert your bolt through the plywood hole, and then add a washer and a nut. Next, insert your wheel, and add the second washer and nut. Make sure the bolt’s end is secured within the chuck of the drill. Place the wood scrap piece underneath the drill, and clamp everything onto the table tightly. Now, lubricate your bolt to lower the friction within the plywood.
  • Step no.5- If in case the wheel (plug) burns during drilling due to friction produced by high speed, you need to push your Drill-Press handle downward for a fraction of a second, and then tap on your Hole Saw’s side two times while continuing with the drilling. Doing so will prevent the clogging of the MDF dust, and the burning. You can use the file to remove the burnt marks.
  • Step no.6- Holding the sharpening compound in your hand; turn the wheel using your other hand. It is an easy step, and it makes the sharpening process effortless.
