VonShef 13/247

Not Just a Knife Sharpener

For the most part, we like this VonShef sharpener for its speed and versatility. Oddly enough, any knife sharpener will allow you to keep your knives in a top-notch condition. But this model can do a bit more than that. Equipped with a scissor sharpening groove and a screwdriver sharpening port, this appliance is also capable of maintaining scissors and screwdrivers. With its help, you'll get to keep your scissors sharp and treat the flat tip issue that often plagues old screwdrivers.

The speed comes from the appliance's 60W of power. It will take the model no more than a few seconds to make the bluntest knife sharper than it ever was. Now, that's the first stage. Stage two will complete the sharpening process. It will hone and polish the blade to a precise, smooth edge.

VonShef 13/247 doesn't just work with kitchen and bread knives but also with sporting knives made from alloy, carbon, or stainless steel. This fact alone already makes this appliance a great choice for hunters and knife enthusiasts.

This knife sharpener isn't just highly versatile and functional but also a rather convenient kitchen appliance. Featuring 17 x 17 x 13.6 centimetres in overall dimensions, it doesn't require a whole lot of space. The cord storage compartment makes the model more portable than most of its peers. And the non-slip suction feet will keep the appliance in place and prevent any potential accidents.

Again, there's a lot to like about this instrument from VonShef. The outstanding versatility extends the range of potential customers. The appliance's functionality allows it to compete with some of the more expensive models. The compact size and a couple of safety features make this product an equally fitting choice for newbies and experienced users.

Lantana Smart Sharp

A More Compact Option

Lantana Smart Sharp isn't this bulky, massive appliance that will take away a lot of your countertop space. It's a simple tool that will let you keep your knives in a tip-top condition. That said, we wouldn't recommend banking too much on that simplicity.

The rubberised moulded handle of this model will ensure a comfortable and tight grip, equally suitable for left- and right-handed individuals. The heavy-duty non-slip rubber base will provide more than enough safety and stability. It will keep the knife sharpener in place on any flat surface, no matter how much force you're willing to apply. Of course, since this is a manual sharpener, you will have to apply quite a bit of force in order to get the most out of it, but that's to be expected from a manual instrument.

For a simple tool, the model is surprisingly versatile. Naturally, it works perfectly fine with straight-edged steel kitchen knives. But it is just as good at keeping those wide serrated knives (also known as bread knives) sharpened and honed, including those knives that feature hardened steel blades.

The shockproof plastic housing with high-grade diamond rods will protect the knife sharpener from drops. On top of that, there are also the hardened tungsten carbide plates and ceramic stone rods that will extend the model's service life by a solid margin.

All in all, Lantana Smart Sharp may not look like it but this professional knife sharpener won't just keep your knives sharpened but also honed and polished. And unlike those bulky appliances, it won't take away your countertop space and will easily fit in a drawer.

What Is a Knife Sharpener?

All cutting tools need care and they must be sharpened one day. We often face this problem when our knives get blunt and, as a result, show poor performance when we need to cut meat, vegetables, and other food. Moreover, you may also have various camping, hunting or cooking knives that require rejuvenation, too. Thus, having a good knife sharpener is surely a must. Some knife sharpeners require certain experience while others are quite easy to use. Our knife sharpener review will help you choose the best model according to your needs.

Furthermore, you may need such useful devices as a food scale and a cooking thermometer in your kitchen.

What Features to Compare

Type and features

First of all, you need to pay attention to the type and features of a knife sharpener. There are several types of knife sharpeners. Electric and mechanical knife sharpeners, as well as whetstone models, are good for everyday use.

  • Electric sharpeners usually have a trapezoid or rectangular body with several grooves for blade sharpening. Each groove includes disks that are made of various abrasive materials. The discs rotate, thereby whetting and polishing the blades. As customers claim, such knife sharpeners are very easy to use, yet, they should stand on a table firmly. Moreover, some knife sharpeners collect metal filings left after the sharpening. This beneficial option will really save your time!
  • Mechanical (manual) knife sharpeners have also got a wide range of options: replaceable abrasive stones, adjustable sharpening angle, etc. Mechanical knife sharpeners are great space-savers and can be used even during campings or trips. However, you need to get the hang of using such sharpeners. Thanks to convenient handles and rubber feet, these sharpeners will not slip out of your hands.
  • As for the whetstones, they have been used to sharpen the knives for ages. Naturally, their shape is being changed over time. They may look like a bar or disc. Some of them are designed for sharpening, while others are developed for polishing and honing. The quality of sharpening with whetstones completely depends on your skills. However, the whetstone knife sharpeners are considered to be the most unpretentious appliances. Note that the measuring marks and other helpful tips will facilitate the use.

Sharpening angle

The sharpening angle determines the quality of sharpening. It is advised to keep the sharpening angle preset by a manufacturer. Furthermore, be mindful of the material and purpose of your knife so as to extend its life. The sharpening angle of 15°-22° is believed to be suitable for kitchen knives, while 22°-30° angle is perfect for grinding hunting and multi-purpose knives. You can also find some knife sharpeners with an adjustable sharpening angle which is a useful feature. Just imagine, you can change the angle of sharpening anytime! But keep in mind that the less it is, the sharper and more fragile the blade will be. The big sharpening angle is typical for heavy-duty knives made of high-strength steel (for example, meat cleavers or bone choppers).

Sharpening stages

The number of sharpening stages depends on the material and condition of your knife. The whetting of metal knives includes the following stages.

  • At the first stage, the rough sharpening eliminates the damages and defects. At this stage, carbide is usually used as an abrasive material.
  • The second stage involves the polishing and refinement carried out by ceramic whetstones or Arkansas stones (the pieces of microcrystalline quartz quarried from open pits in Arkansas State). Once this stage is completed, the blade of your knife becomes smooth and shrill.

Considering the abrasive material, it may be natural or artificial. The latter is manufactured especially for sharpening needs, and artificial materials are considered to be more durable. But if you have knives with serrated or ceramic blades, you will need a special sharpener for them.
