What is Knife Sharpening?
The process of sharpening a knife by grinding against a rough surface is called knife sharpening. The surface can be a soft or hard surface. The hard surface is typically a stone while the soft surface may be reinforced with hard particles such as sandpaper. The other tool for sharpening knives is a razor strop. It is used to polish and straighten the edge.
How to care for your knives?
To cook well you need the right ingredients, the right techniques and the right tools. The basic of the right tool is the steel and its feel. A hard steel knife is made of carbon steel that maintains a sharp edge longer. And the steel is unaffected by moisture and does not rust. Besides having the tools made of the best materials they should feel comfortable and balanced to hold and use.
As a knife is a precision instrument it needs care. Here are a few best practices to get a sharp cutting edge. Always clean your knife with warm soap and water. The harsh detergents, high heat and rattling around in the dishwasher can damage your knife. All knives go dull thus, a whetstone helps to gain the edge back. The knives can be sent out to professionals or there are many manual and electric sharpeners to do the job.
When storing the blades place them in the blade guard to preserve the edge. Use end-grain wooden boards for cutting. The next best option is rubber. Glass and marble blunt and damage the edge due to their hardness.There are two aspects to caring for knives -honing and sharpening.
Honing the knife is pushing the edge of the blade straight and even.A steel rod is used to maintain a sharp edge. Always hone a knife before use. Hold the steel vertically in the non-dominant hand. Tuck the tip to a stable surface for an anchor. Now with the dominant hand hold the knife horizontally at 20°. Then draw the blade downwards across the steel from heel to tip four times each side.
Sharpening is when the blade is shaven and ground to produce a new clean edge. Knives should be sharpened yearly to repair mars and nicks on the edge of the blade. When a knife slides off the onion skin you know your knife needs sharpening. Usually, the chefs use unpolished ceramic or pumice to sharpen the edge. There are electric sharpeners that get you the right edge.
About electric knife sharpeners
The electric knife sharpener is a rectangle shaped box. It has a single or more slot to place the blade in while a motorised wheel turns to sharpen the blade as you push or pull it through. Even though the electric knives are speedy and convenient their cons are they are difficult to control, lack of portabilityand not sharpening the complete edge.
The best electric knife sharpeners usually have three stages with diamond abrasives instead of whetstones. There are slots that guide the knife along the entire length. They can remove the chips and mars from the blade of a variety of knives such as straight and serrated edges.
The right way to use the sharpener is to let it do the work for you. Do not press the knife for a proper operation. These sharpeners are low maintenance and require periodic cleaning to remove the metal shavings. They have turnedand sharpening surfaces, that are powered by motors. When the user places the knife edge into the slot, thegrinding surfaces turns, quickening thewhettingprocess.
Even though most knife users have learnt the accurate whetting process using river rocks and pumice may chefs recommend using the electric sharpeners. This is especially true for places that see many knives dull quickly.They are ideal for commercial kitchens and large eateries such as hostels, canteens, charity homes, etc.
How do electric knife sharpeners work?
The rectangular device has one or more slots. They help angle and hold the blade in the right position when the polishing discs turn to refine the edge. These sharpeners are more efficient than manual sharpeners. This is because they have two to three polishing discs with different grit levels. To use this machine simply turn it on and place the base of theblade in the slot then pull it towards yourself for 2 to 3 times.
Tips to use the electric knife sharpeners
To ensure best results sharpen the knives twice a year. This not only maintains the blade but also conditions them prolonging their life. The knife should be placed at an angle of 15-20 degrees in a slot. Always start from a coarse surface then move to the finest. Most sharpeners have bins and magnets to collect the shards. Always wash and wipe the knife after sharpening. Before you sharpen the knife ensure that the blade fits into the slot in a properly.
Why use electric knife sharpeners?

Essential features ofan electric knife sharpener
There are many sharpeners on the market, but the features expected in a sharpener are as follows:
Non-slip base: As we are dealing with sharp edges here, the sharpener should be easy to use. This prevents cuts and accidents.A non-slip bottom ensures that the device remains in place while sharpening the knife. This also gives traction to the operation while sharpening the blade. Most models come with suction cups that anchor the machine to place.
The number of stages: Most models have more than one stage of sharpening. Most models have 2 stages – one for sharpening the other for honing. There are some with three stages in some with a graded grit from coarse to finer.
Materials: A high-quality sharpener uses diamond abrasives. This is because diamond is a hard material thus the polishing or grinding wheels last a long time. There are less expensive models available made of Sapphirite or polished ceramic or tungsten carbide.
Grit unit: The grit number measures the abrasiveness on the polishing disks. The higher the number the finer is the grinding surface. The 1000 grit material is finer than the 200-grit material which is very coarse.
Precise blade guides: These brackets eliminate guesswork. These brackets hold the knife at the desired angle ensuring a clean result. This feature ensures the same and consistent results each time.
Easy maintenance: metal shards fall off the knife while sharpening. To make it a hazard andmess-free process these devices have magnets, bins and plugs. The grinding wheels are removable to clean the debris inside.

Design and Build
The Sagler sharpens knives like a pro without mistakes and automatically.The sharpener comes with automatic blade guides that position the blade in an ideal position for sharpening and honing. The bottom of the sharpener comes with suction cups that prevent slippage and accidents.The stage one of the sharpening process reshapes the blade at an angle. Then sharpens to rejuvenate the edge. The stage two completes the process by honing and polishing it. The shavings that fall off the blade in the first stage are collected in the receptacle below. Just remove the plug and clean in a snap.
To get the right edge,keep the knife at a 90-degree angle to the table or the base. Insert the heel of the blade into the slot and then pull the knife towards yourself. Do not apply a downward pressure. Let gravity and the weight of the blade do the job.
The Sagler can handle straight edges and serrated edges but not meant for scissors and other outdoor implements. The unit is 9.9 inches in length, 7.3 inches in breadth and 4.9 inches in height. It weighs 2.78 pounds. It is compact in size and build. It hasa tiny footprint on the kitchen counter or drawer.
The Sagler is backed by a 1 Year warranty and it works right out of the box. No assembly required.
