Important factors you should take into consideration before purchasing a knife sharpener.

  • Type of blade.
    Make sure to check your kitchen appliances blade type as it will help you choose the right sharpener for them. If your knives are with straight edges, most types of sharpeners will work perfectly on them. If the tools are with a straight edge on only one side, use precision sharpening, steel or rod sharpeners, some electric sharpeners, etc. If the knives have serrations, you may need a triangular sharpening stone or a ceramic file.
  • Safety.
    Take care of the safety point when choosing a knife sharpener, as it is a dangerous appliance. Working with knives has to be as safe as you can make it, and your sharpener has to become a part of your safety system. Choose one that will be easy to use and convenient to hold, switch on and off, etc.
  • Type of sharpener.
    You may want a knife sharpener that would be applicable for all types of knives you have. There are some ultimate versions, but there are other points to consider when choosing one. Types vary in size, so you need to choose the size that will fit most of your appliances at home. They also differ by portability, which is a huge plus for safety if you choose the right sharpener.
  • Manual vs. automatic.
    Determine what will be easier for you to use: a manual or an automatic sharpener. In the first case, you need to have some skills in sharpening and not many knives to sharp. You also have to make sure manual sharpeners are convenient and safe for you to use. In the second case, think of the place your outlets are and whether it will be comfortable for you to be not far from it to use a corded sharpener. This version will be suitable for those who have lots of knives to sharp.
  • Abrasive material.
    There are five main types of abrasive material used for knife sharpeners. All of them are suitable for most knives, but they provide different sharpening capabilities and results. They all will give you a good result, but you may prefer one particular abrasive option.
    For example, diamond sharpeners are the toughest, they will give you a fast and durable sharpening result. Diamond works best for stainless steel knives and other hard materials.
    Carbides will help you restore the functionality of your knives in 3 to 4 strokes, so it’s the best for a quick refreshing when you are in a rush.
    Ceramics will help you finish the sharpening and maintaining it. You will need to use it often, but your knives will be always sharp.
    Arkansas stones perform two functions simultaneously: they polish the edge of a knife to make it extremely sharp, yet they almost don’t remove metal from the surface.
    Synthetic is a man-made material, and it usually works as a final polishing option to use.
  • Price.
    Different materials, forms, and functionality options will come for a different price. Firstly, you need to consider all the functions you want your knife sharpener to perform, and then think of the price you are ready to pay for a tool.
