Frequently Asked Questions

What is the best knife shape for dicing?

A Santoku or Nakiri is often best. These shapes allow for efficient vertical chopping. They provide excellent control for precise cuts. This makes onion dicing much faster.

Why do onions stick to my knife?

This happens due to surface tension and moisture. Scalloped or hollow-ground edges help prevent this. These designs create air gaps between food and metal. It keeps your workspace much cleaner.

How do I prevent onion fumes?

Using a very sharp knife helps significantly. A sharp edge slices cells instead of crushing them. Crushing releases more gas into the air. This reduces the stinging sensation in eyes.

Is high carbon steel better?

High carbon steel holds an edge longer. It allows for much sharper cutting performance. However, it requires more careful maintenance. You must dry it immediately to prevent rust.

Can I put these knives in the dishwasher?

Most professional knives require hand washing. Dishwashers use harsh chemicals and high heat. This can damage the handle and edge. Hand washing preserves the knife’s lifespan.

The imarku Santoku is our top recommendation for dicing onions. Its scalloped edge effectively prevents sticking during prep. This feature makes onion dicing much more efficient. If you prefer a specialized aesthetic, choose the PAUDIN Nakiri. Its wave pattern provides excellent food release.
