Flexcut KN13

It is easy to fall into using the same knife for just about anything. But the whittling world is much bigger than just one knife, and knowing the difference can help you get the carving you need. 

The size of the project and specifics like that are incredibly crucial in getting the knife you need. You also want to check on the knives’ features to make sure that they can deliver what it is meant to. 

The Flexcut KN13 is a detail knife that you can use to carve out finer details on projects. While your general carving knife may seem like it can do it all for you, the detailing knife will give you the finer detail that your project requires. 

Say, for instance. You want to engrave fine details and make narrow cuts. Then the Flexcut KN13 can do this for you. It has a fine-pointed tip that allows you to make fine cuts. You can also use it to remove more extensive stock if necessary. It is a sharp, efficient blade that you will enjoy using.


Flexcut KN13 detail knife looks pretty basic and will soon become your new best friend when it comes to carving in detail. It looks pretty basic at first glance. The handle is ashwood, which naturally has a light beige hue. 

The straight grain is visible and comes through nicely, creating a pattern that many find to be visually appealing. The handle is finished off with a coat of oil for a smooth look. 

This will serve to protect the oil and also give the handle on the knife a smooth finish. It also has a hook-like shape. This is more for performance than it is for looks. But that’s not to say that the look is not flattering. It almost looks elegant, but at the same time, it just invites you to grab it and start carving. 

The blade is very pointy, and it is made of high carbon steel, which is very strong and can withstand the pressure as you carve. The pointy tip means that you also need to exercise extra caution when handling the knife.

The blade bevel is 1 1/2 inches and is highly polished to a razor-sharp edge. The blade is also thinner than the cutting knife, and it is flexible. The pointy tip comes in handy when you need to get to the hard-to-reach places. 

Performance Review

This knife is very sharp, and the great thing about flex cuts blades is that they remain sharp for a very long period. The pointed tip on the KN13 detail knife makes it possible to cut very fine and precise details. 

For example, this knife will make you very happy if you want to cut geometric shapes with accurate corners and crevices. It has a way of fitting into very tight spaces and carving out those specific shapes very accurately.  The blade is longer, which also helps to get into tight spaces. 

The handle is made of ashwood, which is durable and will keep you carving for longer. It has an ergonomic shape, which helps to reduce hand fatigue as you work. This is one of the advantages that flex cut has over the other brands on the market. 

If the blade is efficient, but the knife feels uncomfortable in your hand, you will not want to carve for long periods, which may mean that you will not take as much time and patience to bring out the necessary carvings. 

One of the most important things to look for in a good carving knife is durability. The KN13 is a durable material that easily slices into almost any wood and does not break. While the blade is very thin and may look like a razor blade, the amount of strength is astounding. 

Don’t be fooled by the 1 1/2-inch blade. It can cut precisely and accurately without flinching. Another great thing about the blade is that it is flexible. This adds to its ability to carve in hard-to-reach places. 


The KN13 detail knife from the flex cut comes ready to use out of the box. It is already sharpened, which means that you will need to be careful when handling it. To further keep your fingers safe, you can use whittling gloves. 

Wear the glove, especially on the hand holding the wood. This will keep your hands safe. Also, make sure that you handle the wood properly as you carve. Avoid splinters and also avoid the blade nicking your fingers. Steer clear of them as you cut.
