Buying Guide: Best Knife For Cutting Onions

For onions’ slippiness’ and chemical characteristics, it needs a specific quality knife such as a chef knife. Let me show you the buying guide to get a specific knife for cutting onions.


High-quality stainless steel is the best material for any knife material. It is especially perfect for dealing with onion characteristics. The Rockwell Hardness Scale should be around 56 to 60. Also, it should be a full tang design; it makes the knife stronger.


As the material is stainless steel; it should be within 5mm thick. A thick blade helps to break down and slice easily.


The handle should be made of wood or molded. It would be better if you choose an ergonomic design handle. Holding anywhere on an ergonomic handle does not affect cutting; that’s the plus point of this design handle.


The balance between the blade and handle should be perfect for cutting any angel perfectly. I found most; the chef knife comes with a well-balanced weight. Also, look at the end cap at the back of the handle; it helps maintain the knife’s balance.


Sometimes a low-priced knife provides a better-quality knife, and sometimes a high-priced knife provides a low-quality knife, but I am not saying that it will always happen the same. I got 4 onion cutting knives, 3 of them are mid-priced, and 1 is high-priced; you can choose one of them without any doubt.
