How much time does the knife-sharpening process take?

It all depends on how badly damaged the edge is and what you use your knife for. Usually, a badly damaged edge will take more effort and much longer to manually sharpen than the one that only requires a touch-up.
For me, on an average, each knife takes around 3 to 5 minutes to give it a good edge that can be fairly maintained with honing on a steel. But it may take close to 30 minutes even if the blade is damaged seriously. But on a seriously damaged blade of a friend I have spent up to 30 minutes

What is the best way to sharpen kitchen knives at home?

Follow the below instructions if you want to do a manual sharpening with a controlled-angle sharpening system:

Selection of the Hone:
• Progress through the hones by starting with a coarser hone and then work your way down to the finest hone.
• The hone you begin with will practically vary and that will depend on the type of sharpening you require.
• For sharpening a very dull edge, always begin with the coarsest hone in the kit (coarse or extra-coarse), and then progress through the medium to the finer.
• For just angle maintenance or regular touch-up to your knives, beginning with the medium hone will do your job.

Sharpening Strokes:
• To get precision, your strokes should go diagonally towards the guide hole in the clamp and along the small section of your blade, covering entire length of the hone as you give each stroke.

Additional tips:
• Giving the same number of strokes for each targeted area of your knife will help ensure a uniformly along the sharpened blade.

Some people argue that electric sharpening of knives is bad for the blade, is this true?

This is not true. Any sharpener can damage your blade if you do not use it properly. Practically speaking, while each of the options – electric knife sharpeners, sharpening steels and sharpening stones serves the same purpose, they’re absolutely unique in delivering results. You should exactly know what your need is to be effectively able to decide easily which type will suit to your requirement. You will certainly get the precise angle as you get from manual ones in an entirely effortless and easy way just using one hand and without mastering the art of manual sharpening. Just set the machine to your own preferences and insert the blade into the sharpener allowing it to do all of the work within a few seconds!

How can I keep my knives sharp after sharpening?

In course of time, edges will lose their sharpness as we keep using our knives, even though we have sharpened them to the perfect angles. So it is inevitable that after certain intervals you should sharpen your knives to keep your cutting job perfect all year round. But certainly you can delay the process of being dull by following the below rules:

• Separate your knives for crushing/slicing heavier items and for cutting softer items. By doing so you can save most of your knives from being dull fast
• Wash your knives immediately after using and dry with a towel. Those that you do not use frequently, store them in a knife rack or in a drawer to prevent rust from forming
• Do not accomplish tasks that they are not meant to perform (eg. Opening plastic/aluminum containers, cutting hard outer foils or paper boards etc)
• Do not use too hard chopping boards made of glass/stones as they will damage your knives. Instead use a soft plastic/wooden board.
• Use proper techniques of cutting
