What Exactly Is A False Edge On A Knife?

A false edge on a knife is essentially a false cutting edge manufactured into the back of the blade. It’s usually nothing more than an optical illusion created by the grind lines, which give the illusion of two cutting edges. Most manufacturers do this for visual enhancement or ergonomic grips for certain knife designs. However, it does not contribute to the practical use of the blade and does not improve its sharpness or performance in any way.

Different Types of False Edge Knives

A false edge on a knife is a sharpened but not necessarily sharp enough to effectively pierce the material being cut. It creates the look of two blades, but is actually one blade. False edges can be seen on common pocket knives, daggers, swords and even some kitchen knives.

False edges are usually ground at angles less than those used for actual cutting edges. They allow a person to produce more pressure on the side of the material being cut which could create a cleaner cut result while using less force. This would be helpful with materials such as rope or leather which are difficult to cut through.

Another use of a false edge includes back-sawing, which involves pushing forward as opposed to slicing backward in order to make angled cuts into hardwood or fresh lumber pieces like laminate floorboards, preventing their splitting during sawing action. Thus producing neat and straight lines throughout the sawing action.

False edging also provides superior ergonomics when dealing with aggressive thrusting actions where leverage and control become important such as digging holes with smooth surfaces or from punching through thick leather materials such as belts and wallets among other activities where similar motions are absolute necessities.

In addition, false edges provide improved grip when manipulating a knife in tight spaces during delicate tasks because they occur along one side of the blade’s profile instead of both sides enhancing one’s control over it during slippery applications such as skinning animals for food production or creating precise scroll cuts in hardwoods among other operational uses where accuracy is important.

How a False Edge Works

A false edge on a knife is a sharpened edge that appears to be double-edged, but actually only has one functional side. This “false edge” makes the blade look like it has two working edges when looked at from the side and provides stronger cutting power than a single-edged blade would have with the same amount of steel. It does this by maximizing material that can be ground for sharpening on both sides of the blade, precisely controlling just how much steel is used for cutting. Many knives, including larger swords and bayonets, incorporate this feature as it increases cutting efficiency without compromising strength or weight. False edges are also beneficial in concealment knives because they look proportionate while simultaneously increasing usability without extending their length.

Benefits of a False Edge Knife

A false edge on a knife is when one side of the blade has a sharp edge but the other side appears to be sharpened but is actually not. It looks like the edge goes all the way across, creating a false impression that it is sharpened, but in reality it isn’t and can’t be used for cutting. This feature is beneficial for many reasons, as it cuts down on weight and also creates less drag when slicing through material. False edges also make for easier maintenance, because there are no actual cutting edges to sharpen or strop, so cleaning and oiling will suffice. Finally, using a false edge knife allows for greater control when accessing hard-to-reach places with the blade, as well as making light work of intricate combative or prepping tasks where precision is essential due to the low drag effect of the unsharpened side of the blade.

Drawbacks of a False Edge Knife

A false edge on a knife is when the very edge of the blade is sharpened but not the full length of it. False edges work well for fine slicing and piercing, since they make that part of the blade thinner and sharper. However, they may also weaken a blade’s strength and compromise its durability in other ways. False edges require more frequent care and maintenance, as they are easily damaged or worn down by everyday use. They won’t be able to hold an edge as long as one without a false edge. Sharpening them can be difficult due to the small amount of steel present and the sharper angle required to sharpen them effectively. Finally, having an awkward flatness along one side of the edge can reduce efficiency when cutting through tough materials or materials with wider grains.

Types of Cuts That Best Utilize the False Edge

A false edge is an unsharpened section or groove of a knife blade. It can be used to create beveled or chiseled edges, as well as providing a surface for dull scraping tasks. Several types of cuts are best completed with the use of a false edge on a knife.

Chisel cuts are one example of cut that is often accomplished using this technique. False edges can be utilized to make deeper, even notches in materials such as bone and hardwood. The narrow tip provides enhanced control and accuracy when refining intricate angles from the material being cut.

Honing is another use for false edges. Honing requires the user to run their index finger along the back of the blade in order to create sharp, precise lines in whatever material is being worked on. This creates greater consistency and raises the overall precision of your work when dealing with delicate materials like woodcarving projects or jewelry making endeavors that require extreme accuracy.

False edges can also be used to partially sharpen blades depending on their thickness, shape, and size of the groove carved into them. The use of this technique allows individuals who lack access to professional sharpening services or specific tools needed to accomplish these types of sharpening tasks, an alternative method that uses much simpler implements, such as sandpaper or hone stones.

Maintenance Tips for Ensuring a Sharp False Edge

A false edge is the thin, unsharpened backside of a knife blade. It is used for creating finer cuts, like peeling fruits and vegetables, as well as for decorative or ornamental purposes. A sharp false edge can be a useful feature to have on your knife. Here are some maintenance tips to ensure you always have an optimally sharpened false edge on your knife:

• Initially sharpen the true edge of the blade with a professional grade sharpening stone before attempting to sharpen the false edge. This will help ensure uniformity between both edges.
• Utilize a specialized sharpening rod specifically designed for false edges; this type of rod is especially suited for fine-tuned honing due to its size and length characteristics.
• Use only medium grit abrasives when honing the item—using too coarse of an abrasive may cause damage to the edge’s structure and integrity.
• When working along the areas where the true and false edges meet, pay extra attention to stop short of contacting or damaging either edge.
• Regularly strop or hone both edges with an even pressure—focusing more on gently “polishing” than actually removing additional burrs. Strop it every couple weeks or so depending on how often you use your knife.
• Finally, after finishing your honing session, inspect with a loupe or magnifier so you can make sure your sharpened false edge is well balanced and without faultlines in its alloy structure


A false edge on a knife is an unsharpened edge that looks sharp from a distance. This can be a great asset for those looking to add another layer of protection to their knives. False edges are beneficial for self-defense, since any attacker that attempts to take the knife will be met with resistance because they think the blade is sharp when it isn’t. Additionally, false edges provide extra stability when cutting through difficult materials like rope or wood. The added weight at the back of the blade helps guide it through tough surfaces and reduces fatigue due to prolonged use. Finally, sometimes referred to as “false honing”, false edging can help reduce dulling caused by constant abrasion from outside elements such as dirt, dust, or sand. Overall, adding a false edge to your knife can be very advantageous for defense and cutting applications alike.
