A Dull Knife is Safer!? Well, It Is a Myth!
Any knife requires regular maintenance for retaining its sharpness. It is a misconception that a dull knife is less likely to cut a finger. With a blunt knife, you will have to apply extra force to cut the way you want it. It may result in slipping or cutting your finger. On the other hand, a knife with a well-sharpened edge does not need much force, which makes it more secure.

Is Sharpening and Honing the Same?
Types of Knife Sharpeners
Manual Knife Sharpener
Sharpening Stones- What to buy in 2021
Oil Stone: This is the most affordable type of sharpening stone but has a slower cutting rate. The oil is quite messy, but there is no substitute for it if you want a fine finish. Oil stones are usually seen in hardware stores. The Arkansas oil stone is quite popular and comes in various grades. Washita is coarsest and very soft due to which it is avoided. Hard Arkansas is rare and expensive. Soft Arkansas is finer for having a smooth polished edge. The Indian stone made of aluminum oxide is more famous for an excellent finish.
- Water Stone: This is a better option than an oil stone if your priority is quick cuts and easy cleanup. Since it’s made of aluminum oxide, it is very abrasive and soft and will wear away faster. So, you need to flatten it quite often. Water stones are made of natural or synthetic materials, but the natural ones are costlier and rarer to find.
- Diamond Stone/Plate: Cleaning such a stone is easy, as it needs only a wire brush that discards shavings and small particles. Such stones are becoming popular because they can cut faster and prevent a recession in the sharpening surface. The durable diamond material has a metal plate holding micro-sized diamonds in it, with or without surface holes. The ones with holes are more popular and capable of sharpening better and faster. You may use the stone dry or wet. It is best to use it wet, as it prevents the diamond abrasive from weighing up with the removed particles.
- Ceramic Stone: Is a modern alternative but an early substitute for a natural sharpening stone. You can also find them as long rods or sticks with a handle just like sharpening steels or as pre-angled notches. Just like other stones, ceramic is manufactured using minerals. It has a less porous texture. Hence you need to soak it for a few minutes for saturating the pores. The ceramic stones are available at different qualities. A few are extremely soft, while some are quite hard. Because all knife steels tend to differ, you need to choose a ceramic stone suited to your knife. Ceramic stones are a good choice for single-edged knives.
- Natural Stone: Is the sharpening stone used widely in ancient Europe and Japan. Good quality natural stone is expensive due to very few operative mines. Natural stones tend to give a lasting edge due to random grits that result in serration of various sizes. You can consider such a stone best for sharpening the Japanese knives having a single bevel.
- Synthetic Stone: It is gaining more popularity than natural stones. It is usually made of fused aluminum grit perched in resin. While a few synthetics demand water soak before use, the rest need a splash. You will find different synthetic stones, including soft steel or firm steel. Consider using an artificial water stone for western-style steel knives. But, some will work nicely on the traditional, single-sided, Japanese edges.

How to Choose the Best Knife Sharpener
Now that you know about the different types of knife sharpeners let’s discuss some factors you should consider.
Factor 1 – Types of Knives:
Which knives do you use in the kitchen? If you know this, you know which sharpener is better for you. While all sharpeners are capable of sharpening knives with straight edges, only a few are capable of handling serrated ones. Since serrated knives break down gradually, you might not need a special sharpener if you do not use it often. You will need a special sharpener for sport or Asian-style knives having edge narrower than a regular kitchen knife.
Moreover, if you are choosing an electric or manual sharpener, it is essential to know that some models (regardless of the type) might end up over grinding the knife, which may result in a reduced lifespan of its blade, chipping, and/or warping. To control this issue, consider a sharpener that does not emit much heat and is metal friendly, especially if your knife is expensive.
Factor 2 – Your Patience:
If this is not much within you, an electric sharpener is the best deal. A sharpening stone usually has a long learning curve, although it is easy to use.
Factor 3 – Your Need for Speed:
Consider how you would like how fast you would need to get your sharpening done. Each sharpener performs at a different pace. If you need something that works quickly, a pull-through or an electric sharpener is ideal.
Factor 4 – Type of Blade Bevel
- Convex: Has an outwardly twisting taper that aims to retain more metal at the rear of the edge. This makes the blade stronger while yet maintaining an average level of sharpness. Most cleavers have this kind of bevel. Such a bevel of the edge needs an expert hand on a sharpening stone.
- Hollow: Has an inward taper, which is just in contrast to the convex bevel. This kind of bevel gives an extremely sharp edge, but it is quite fragile. Such a bevel is usually found on straight razors.
- Flat: Has a taper starting at the blade’s spine. Such a bevel is quite sharp, but it is challenging to create due to the quantity of metal to be discarded. This is the reason why such a bevel type is limited in its commercial use.
- Chisel: Features one side as ground down and the other as entirely flat. Such a bevel offers a very sharp edge due to which it is usually seen on Asian cooking knives. Depending upon the side on which the bevel exists, left- and right-handed options are also available.
- Double/Compound: This is usually seen on Western kitchen knives. Another back bevel is added over the edge bevel to boost the cutting ability of the blade. Although not much sharp as other types, the double bevel is admired for its resilience as well as strength.
- V/Sabre: It is much like a flat bevel but with a taper that starts around the blade’s middle area and not from the spine. This kind of bevel is seen on different types of kitchen knives, as it gives a lasting edge.
Factor 5 – Blade Angle
12-18: Are for knives that are designed to be very sharp, such as paring. As the angles result in a weaker blade, they usually are considered for models that are designed to perform much of fine slicing. An angle below this range is used explicitly for razors.
18-25: Are found on the majority of kitchen knives. The angles in this range make up for a subtle balance between durability and sharpness. These angles are standard on Chef’s knives.
25-30: Are seen on many types of outdoor utility knives, such as pocket models. This is because these knives should be able to cut and slice under challenging situations. Hence they need to be durable. So, such knives have a high blade angle.
30-35: Are usually seen on cleavers and blades that are specifically designed for chopping. Chopping needs a lot of force that such large-angle blades need to be strong and durable.
Factor 6 – Type of Knife
Factor 7 – Angle Selection
Most Japanese knife makers use hard steel and a lower angle for more sharpness. But, Western blades have a higher angle and made of softer steel. If you have both types of knives, it is essential to choose a knife sharpener that allows you to set different sharpening angles. The knives are designed to perform at its factory bevel angles. It is wise and best to retain them at those angles.
Factor 8 – Number of Stages
Factor 9 – Sharpening Space:
A manual sharpener is ideal if you have space crunch for sharpening. On the contrary, an electric version needs more space.
Factor 10 – Budget:
Usually, several manual sharpeners are cheaper than their electric counterparts. They also cost less to maintain, due to no moving parts that can easily malfunction at some time or the other.
Factor 11 – Noise Level:
Well, for those who do not know, a few electric sharpeners are noisy. There is some kind of scraping sound of the blade, which can be annoying to some people. So, if noise bothers you, check for its noise level.
Factor 12 – Working with Left Hand:
Several manual and electric sharpeners are usable even with the left hand. Make sure that while buying, as some are specifically for right-handed persons.
Qualities of a Good Knife Sharpener
- Superb Sharpness and Performance: The most reliable test of sharpness is to use a knife to slice a tomato. If the knife is nicely sharpened, it should be able to penetrate the skin of a tomato without any effort. A sharpener’s most critical quality is its ability to give a sharp edge without making any scratches.
- Precise and Flexible Angle Guide: A few knife sharpeners allow even a naive to position blade at the right angle. However, many models require all its users to practice a bit. The best sharpener has the best angle guides that are adaptable to embrace several blade angles, precisely 15 and 20 degrees. These two are the most common angles for kitchen knives.
- Abrasive and Hard Surface: Of all the sharpening materials, diamond is the hardest and fastest. Polished ceramic and tungsten carbide follow. Abrasiveness is measured in grits. The higher the number, the finer is abrasive. Thus, a material of 800-grit is very fine, and 120-grit is very coarse.
- Multiple Stages of Sharpening: You need at least two stages — coarse material for restoring dull or damaged edges and finer material for polishing and touch-ups. You cannot use coarse material for touch-ups, as doing so discards too much steel.
- Proper Safety: Usually, it is easy to sharpen without scraping your fingers. In manual sharpeners, this is ensured by inserting a physical blockade between the blade and fingers. Electric knife sharpeners rely on slots to escort the knife into the targeted belt, and not into your fingers.
- Excellent Warranty: This is much needed for an electric sharpener and should also offer prompt and satisfactory customer service.
