To chop or dice an onion you would need to have a sharp knife. The regular serrated kitchen knives might not be able to provide clean and concise cuts. To cut onions evenly you would need to get a chef knife with a plain blade.
Onions are one of the most commonly used veggies in almost every meal. So having a sharp onion dicer in your kitchen drawer is essential. It doesn’t matter whether you are a home cook or a professional chef; you have to make sure that you have the right knife for managing your kitchen affairs. If you are looking for a durable and sharp knife for cutting onions, you must read this post.
How to Choose the Best Knife to Cut Onions?
Here we have discussed some points that you need to consider before you buy the best knife for cutting onions!
• Steel Quality
When you are looking for the best knife for dicing or chopping onions, you have to go for high-quality stainless steel. Stainless steel material is best for dealing with onion cutting. Also, make sure that the steel blade comes with a full tang design, as it would add to the strength of the knife.
• Blade Thickness
Other than being stainless steel, the blade should also be thick. The best knife to cut onions is one which is at least 5 mm thick. A thick blade helps in easy slicing.
• Handle
The handle of the knife must always be strong and comfortable. It should be made of wood or plastic molded material which would prevent slipperiness. Having an ergonomic handle design is a plus!
• Balance
You have to make sure that you purchase a knife that has an ideal balance between the handle and the blade. If the knife is not balanced, it will either bend or break!
• Budget
The high price of a knife doesn’t promise quality. When buying a knife, you have to make sure that you go for value-to-money products. You must always get a knife that falls into your budget.
In the section below, we are going to explore the best knives for cutting onions and other food items. There are over hundreds of knives available on Amazon, but here you are going to find the ones that are sharp, thick, sturdy, and durable.
