The end to end length of the knife is 31 centimeters with the blade measuring 18 centimeters. The knife comes in a black packing box that also serves as its storage box when it is not in use.


What we liked about this knife is the perfectly balanced full-scale blade that makes cutting using the knife fast and quick.

Each of the knives has a differently colored blade and a matching color on the handle. The set also includes a clear acrylic storage block with ports that fit each of the knife when not in use.


We like the resin coating on each of the knives' blade because it is corrosion resistant. Moreover, it enhances the separation of the food items being cut by the blade, thereby making it easier to clean. Color coded blades also prevent cross contamination that can occur when the same blade is used to cut different foods like meat and vegetables.

All blades are mirror polished at the top edge of the blades while the lower part has a graze finish. Handles are black in color and feature soft grip silicon material both at the top and bottom.


We like the blade on this knife because it is different from other knives that come with the grazed edge and mirror polished finish. This makes the blades have nice aesthetics and enables the blades to resist rusting and staining. All knives come with protective sheaths that fit over the blades when they are not in use.

This knife's beautifully designed Damascus blade is one of the things our team liked about the knife. The inverted triangular shape fits well in the cook's hand and makes it easy to cut food items. The laminated handle is tightly sealed with a stainless steel cap at the tip to protect the blade from moisture and humidity. This works to protect the knife from rust and corrosion.

The blades have an FDA approved resin coating and are made of high-carbon steel material. Each of the knife's handle is ergonomic and perfectly balanced with the blade's weight.

Handles that are firmly fitted to the body of the knife enable the diner to hold the knife comfortably and cut with minimal effort.

Users who have previously used this knife report its outstanding performance when cutting through herbs and vegetables because it enables them to achieve intact thin slices.

What Features to Consider When Choosing a Knife?

When choosing a Kai knife for use in your kitchen, you need to consider some of the factors we have discussed in the section below:

The Materials used to make the Knife

The materials used to make the knife should be of superior quality. If the knife has any non-stick coating on the blade, be sure to confirm that it is approved as safe for food handling by regulating authorities such as the FDA.

Stainless knives and fruits on the table top

The handles on a good Kai knife should be resistant to moisture and humidity absorption, which will enable the knife to last for a long time.


Pick a knife that is guaranteed to serve you for a long time when you follow proper maintenance guidelines. Proper maintenance could include only hand washing the knife and never cleaning it in the dishwasher. Ensure that the knife is also thoroughly dried before being placed in storage.

Storing the knife should only be with other stainless steel utensils. Avoid keeping the knife in drawers that contain iron utensils because they are prone to rust.
