Types Of Knife Sharpeners

Knife sharpeners has different types. Some of the most popular types are honing rod, whetstones, electric device along with abrasive belts and pull-through sharpener. Below we will discuss the aspects you should know about knives and sharpeners which will help us select the best one.

Grit Abrasive

Grits are small and hard sand-sized abrasive particles made of diamond, sand, or other materials. The number of grits on a sharpener indicates how finely it can sharp a surface. If a sharpener has a low number of grits, it will remove more particles from the blade and make it rough. These types of sharpeners are used to renovate and repair the old and damaged knives. In the same way, if a sharpener has a large amount of grit, it will finely sharp the blade and make it good as new. 

Sharpeners that use grit abrasive are whetstones, sandpaper, and abrasive belts. However, the sharpeners do not come with clear grit numbers so it is important to follow the instructions provided by the manufacturers to pick the best one. Pull-through sharpeners can also be multi-staged in which the first stage is usually the coarsest and used to refine the damaged blade while the later stages are used to finely sharpening the blade.

Blade Grind And Knife-Edge

Blade grind is the cross-sectional shape of the blade that is used to produce the cutting edge. The most common edge styles include flat, taper, hollow, chisel, and convex. It is important to understand the blade grind of your knife before you buy any sharpener because there are different types of sharpeners for different blade grind. You can choose the most efficient one depending upon which knife you have. In case you have different blade grinds, the best option will be to choose the one which is useful for the majority of your knives.

Edge angle, also known as edge bevel, is an angle in which the cutting edge is cut to form a sharp tip of the blade.  The most common styles of edge angle for chef knives are Asian and western. Asian knives are designed for cutting fish and vegetables. These knives have a finer angle between 13-15 degrees which allows precise slicing and detailed trimming. The western style has 20 degrees wide-angle edge blades that are useful for cutting meat and tough vegetables. Finer angles are fragile, and the edge can roll to the side after heavy use. Whereas, wider angles are stronger and used for cutting and splitting tougher foods.

In an ideal case, all of your knives should belong to either Asian or western style with the same blade grind so you could simply choose the one that is designed for that particular type. However, that is not the case as most people keep different knives for different purposes, in that case, you have probably need to buy more than one pull-through sharpener. Additionally, you can also use a semi-manual or manual tools like waterstones, oilstones, or any other full sharpening tool for all of your knives.

Serrated Knives

Serrated knives have toothlike edges and are used for cutting foods that have a hard exterior and a soft interior. Such knives do not require sharpening on a regular basis but when they do, it is not easy due to their structure. A pull-through and stone sharpener can be used to sharpen the edges a little bit, but it may require another sharpener to sharpening the spaces in-between the teeth.

We cannot determine the exact time to sharpen a knife as it depends upon different factors including the type of sharpening device, the type, size, material, and roughness of the knife, as well as the desired sharpness level. Here is an estimated time to sharpening a knife to its maximum level depending upon the type of sharpener used.

Chef’sChoice XV Professional – Best Electric Sharpener

Since all knives dull with use, it’s important to protect your cutlery investments with the right maintenance tools. A knife’s long-term performance depends on how it is resharpened. Knives made of the finest steel will hold an edge longer, but even the best of knives dull with use- and the initial factory edge only lasts for the first few days or weeks of use.

Than for more than 99% of a knife’s useful life, it’s edge performance depends on how it is resharpened. Replicating the initial factory edge is not particularly relevant, especially since today’s modern sharpeners can apply a better factory edge on every knife.

Stage 1:

Diamond abrasives on the conical disks in Stage 1 create extremely fine ‘micro-grooves’ on the facets on both sides of the edge. It simultaneously creates the first major bevel of the arch-shaped edge at about a 15-degree angle. These micro-grooves on the edge facets give the knife more ‘bite.’


Stage 2:

Even finer diamond abrasives on the conical disks in Stage 2 shape the second and smaller bevel of the arch-shaped edge simultaneously creating even finer micro-grooves on the second bevel of the razor-sharp edge (at a slightly larger angle).

Stage3:

Uses the patented flexible abrasive stropping disk system―to create a microscopically smooth, non-serrated ultra-sharp edge. It creates the third and still smaller bevel of the arch-shaped edge. The stropping action of Stage 3 further polishes the micro-grooves, formed on the edge facets in Stages 1 and 2, to create micro-flutes along the edges of the micro-grooves that assist in the cutting action of an edge of unprecedented sharpness, performance and durability.

Pros

  • Easy to use
  • Sharpens and hones straight and serrated knives
