Flexcut KN14 Roughing Knife Review

Are you considering the Flexcut KN14 roughing knife? Wood carving is an art that requires the use of different blades. This can only come about when you know what to look for in a carving knife. 

How you choose the knife that you want is determined by different factors and features. One of those is knowing the project that you want to work on and the wood that you will be working on. 

This will give you an idea of the blade type that you need and the dimensions you should be on the lookout for. Some carving knives are made only for bigger projects and general carving, and they will not put a dent on smaller, more intricate projects.

Caricatures need a more precise and accurate blade that can carve detail well. Whereas trying to carve a canoe using a detail knife can prove to be nearly impossible. 

Choosing the right type of knife to carve with is almost as important as knowing what to do with it once it is in your possession. A roughing knife, in general, is used to get rid of a larger stock. It is characterized by thicker and longer blades than the general carving knife or the detail knife. 

This is the knife that you need to get when you want to remove large amounts of wood as you carve, and in the process, make sure that you do not damage the blade. 

The Flexcut KN14 has a large blade compared to the other blades on the other carving knives. The blade serves the purpose of removing a considerable amount of stock. Let us take a look at all that this knife has to offer you.


Whilst looks may not be everything, they can not be ignored even when it comes to woodshop tools. The KN14 roughing knife has a considerably larger blade than the other flex cut tools that you are used to. 

The blade is 1 3/4 inches, and it is straight. It is made of high carbon steel and highly polished, giving it a bright and appealing look. It looks just as sharp as it is. 

The handle is made of ashwood and is very durable. One of the most distinct things about this knife is that it has a light beige hue that elegantly displays the straight grains, which is a well sought-after look for furniture and wooden products.

It is durable and aesthetically pleasing. For the KN14 handle, it adds a clean look that is comfortable depending on how you decide to hold it. If you do it properly, then you should not have any issues with hand fatigue or cramps. 

It also has the Flexcut logo slapped right across the handle in red. It is quite difficult to miss.  The handle is shaped like a hook and this is not just for looks but also helps with the functionality perspective. 

You will also notice that the handle looks somewhat shiny when you first use it. This is due to an oil covering that is used to preserve the wood but to also make sure that it has a certain look. It is a basic, clean-looking knife that can easily fit in with the rest of the tools in the shed.

Performance Review

This is a high-performing knife when it comes to removing large amounts of stock. The Blade is 1 3/4 inches and is straight. This means that it can get straight to the intended purpose. 

The length also makes it capable of removing more stock. The blade is razor-sharp and will easily slice through some of the toughest wood. 

It is also very durable, and this is a necessary feature when looking for a roughing knife. It will not hold up when you put it to the test if it is a flimsy knife. 

Synonymous with flex cuts knives, the handle has an ergonomic design, making it easy to work longer periods. It is very comfortable in hand and is easy to use. 

The blade is flexible and yet durable. This makes it a great buy for beginning whittlers. A rare combination that often lacks in competing brands.


This blade comes very sharp right out of the box, which means that you have to be careful when handling it. The sharpness is both a blessing and a curse. 

You can avoid any accidents by wearing a pair of whittling gloves, especially on the hand that you are holding the block of wood. This will help you avoid splinters and also keep you from nicking your fingers with the blade as you work. 

Sometimes when roughing a block of wood, you use a bit more force than when slicing of shavings. This requires that you position the knife and the wood properly and avoid possibly slipping and cutting yourself. Some people also use thumb guards to protect their thumbs.

Who is this product ideal for?

This product is great for all levels of whittlers, including beginners. It is easy to use. Just make sure that you have the right idea. A lesson or two on using the knife will be beneficial and help you get the most out of your knife and give you the carving that you want to make.


  • It is durable
  • It is versatile
  • The blade comes ready to use and very sharp
  • The long blade means that you can get more work done faster.


  • It does not have a sheath that will allow you to safely carry it around.

Our Verdict

We recommend this roughing knife because it has all that is necessary to make a great carving. Roughing requires removing large amounts of wood, which is thanks to the long blade that the KN14 has.
