Flexcut KN12 Cutting Knife Review [UPDATED]

Are you looking for the best cutting knife on the market? How does the Flexcut KN12 sound? Whether you are a hobby carver or a professional wood carver, you still need the best tools possible. As a hobby, it’s very satisfying and fulfilling.

Cutting a block of wood and achieving a certain predetermined shape always advances the art of woodcarving. Cutting wood requires a certain caliber of tools.

Flexcut KN12

The knife you use must be sharp and suitable for the task. It must have features such as a flexible blade and be versatile and easy to handle.

The KN12 Cutting knife is a general cutting knife, and you will find it very handy to take with you and carve several different projects. Sometimes all you want to do is use one knife to complete what you are doing. 

A handy general compact knife means that you can use it. This knife has a sturdy construction, meaning that you can trust it to cut through just about any wood. A general cutting knife should withstand this pressure, and the Flexcut KN12 has that capacity. 

The blade is durable, and so is the handle. It is a well-put-together knife that you will not regret buying. Let us look at all that you will be getting with the KN12 cutting knife.

Flexcut KN12 Aesthetics

The Flexcut KN12 is a basic-looking knife with a shorter blade than the handle. The handle has an ergonomic handle and a hook-like shape, which is a specific shape made to make handling the knife easier and more comfortable. 

While the shape is cool to look at, it is also functional. The handle is made of ashwood, which comes from the ash tree. It is known for its durability and strength. This is a very welcome feature in a knife used for general cutting. 

You do not need to be carrying around an entire tool kit just for general work. This one will do it all for you. As is the nature with ashwood, the straight grain is visible, making for an aesthetically pleasing look. 

You will find that many modern pieces of furniture have a look resembling this. It is a light hue of brown and gives off a clean look, which is very appealing. 

The blade is very sharp, and it looks the part. It has a more rounded edge at the tip of the blade. You will not need to worry about inadvertently stabbing yourself when using this knife. 

It features edge-holding steel, just like you would find on other Flex Cut blades. The carbon steel blade itself is a dark color.

Performance Review

As a general cutting knife, it is essential to be very durable and can take the heat. The good thing about how Flexcut makes its knives is that the handle is strong wood. Ashwood is notoriously durable. 

The handle’s ergonomic shape also makes it comfortable to hold and helps get rid of hand fatigue as you work. Regardless of how complex the wood you are going to be cutting is, the strength of this tool is outstanding. 

The blade comes already sharpened right out of the packet and is very sharp. It easily slices through the toughest wood because it is high-carbon steel. Durable steel and something that you can rely on. 

While it may not be the best knife for detailing, the KN12 will do a great job of general cutting. To get the best performance from it, make sure you have a comfortable grip on both the wood and the knife. 


It comes already sharpened right out of the box. Because of this, you must be very careful when you take the knife out of the packet. Even after you use it for a while, it maintains its sharpness. When it does go blunt, you can sharpen it. 

The sharp blade needs to be kept safely out of the reach of children. This means that you need to take special care to put it away after you have used it. 

Also, make sure to hold the knife comfortably and away from your fingers. Some people prefer to use their thumb to pivot the wood and get the necessary grip.

Who is this product ideal for?

This is an easy knife to use and can be used by beginners. It is not a technical knife. However, you will need a couple of lessons on keeping yourself safe and how to get the best out of it. 

The project that you start with may not be the absolute best, but this is something that you will improve with time and practice and a good knife like the KN12.  


  • It has a flexible blade
  • It is accurate
  • It is designed to fit comfortably in hand. 
  • It is sharp
  • It is ready to use right out of the box

Our Verdict

This knife fits very well in hand, and you will have no problems even when carving for hours. This is thanks to the ergonomic design of the handle.

With some knives on the market, hand fatigue is a big problem and can cause you to shortcut your project and shortchange yourself.

We also love the blade and how flexible and sharp it is. You will not regret buying this knife as a general cutting knife as it allows you to do all general carving.

For starters, this is also a great way to get used to working with wood and improve your craft. Have fun browsing! See the Flexcut KNL26 left-handed hook knife review.
