Abrasive stropping disk system in this stage results in knives with a non-serrated ultra-sharp edge that is ini smoother.
This sharpener creates a 15° edge angle per side on all knives, whether they be Asian, European or American made. It makes two upper bezels about the cutting edge.

WHY DOES A KNIFE GET DULL/BLUNT IN THE FIRST PLACE?
Before going to the knife sharpening reviews and techniques, allow me quickly shed some light on how exactly do the razor sharp blades get dull.
(I am what people call a ‘mad knife lover.’ I love knives! So pardon me if I get too excited!)
So, everything has to do with the property of abrasion, which is a process of wearing away of a surface by what we call friction.
As we all know, the force of friction acts between all moving bodies, which are in contact with one another. So when cutting stuff with your blade, it is in contact with other bodies such as vegetables. Upon slicing these vegetables, the surface of knife and surface of veggies wear off on each other.
So, the edge of a blade gets microscopically deformed and eroded over time. Also, keep in mind that the metal of the blade can be etched by the acidic substances in the food items we slice. And the result? A blunt blade that can’t dice even a tomato properly.
See the image below to further understand the process.
So what makes it razor sharp.. again?
There are precisely 3 steps when it comes to restoring a blade’s edge to its former glory.
Steps To Sharpen Any Knife: –
- Sharpening: removing extra material from the blade to form a new sharper edge.
- Straightening or Honing: straightening the existing edge of the blade to make it more efficient.
- Polishing or Stropping: giving a mirror finish, without notably altering the edge.
Knife Sharpener Buying Guide
There are two broad categories of knife sharpeners: –
- The manual ones and
- Their electric counterparts
SO this raises another question. Which one should you buy? Electric or manual?
It depends on what you want. Let us break it down. Very quickly.
Manual Knife Sharpeners
A manual one would give you more control over the whole process.
Manual sharpeners are simple to use and usually, have two wheels that intersect and rotate when a knife is inserted, creating an angle for sharpening the edge.
The downside is that they are much slower than their electric counterparts. Plus, they can not sharpen ALL kinds of knives.
Electric Knife Sharpeners
The electric ones give you faster results in an easier and convenient way.
We say easy because the only skill the user requires to operate these is that of being able to turn the machine on and off.
Electric sharpeners have what they call “sharpening stages” which is something the manual ones do not have.
The downsides of an electric knife sharpener are:
They are not VERY safe to use. Any manual sharpener could be considered more ‘risk-free,’ even when if it is compared to best electric knife sharpener out there as they tend to heat up the metal in the blade which damages the material over time.
I hope you got a rough idea about what these two kinds of sharpeners are. Both are great, but with their own flaws and setbacks.
Besides from the manual and electric sharpeners, in the first category, we’ve put together some sharpening stones, pocket knife sharpeners, and knife sharpening systems.
As for the second category, we would be looking at products that we can use for honing our knives: Steel rods.
And as for the last process, ‘the stropping’, we will be looking at the best leather strops available in the market right now.
Remember: Stropping makes sure that your blade STAYS SHARP and clean. It is very essential for the longevity of your knife and is something we, at WaspKnife, would never under-emphasize.
