What Are The Benefits Of A Flat Grind Blade On A Fixed Blade Survival Knife?

The flat grind blade style is a relatively new style of blade design. While the majority of blades in possession by knife enthusiasts are ball-bearing type or concave-grind blades.

These styles facilitate faster, more efficient cutting processes by permitting the user to set the angle of the knife’sblade as it passes through an object. This “set” or “lock” ofthe angle allows for more control over how the knife is used.

It also reduces plastic consumption as less material is required to make the blade. These benefits apply whether using a single piece of wood,or several stacked together.

Less prone to getting caught on things

A flat grind blade on a survival knife is an excellent choice if you need a fixed blade. While a convex grind offers some flexibility, a flat grind makes it easier to register things such as thick roots or animals.

A flat grind offers greater strength and stability when doing heavy work such as chopping or drilling. This quality comes at a cost, though! A thin blade can be highly expensive to make and engrave.

For instance, cost-conscious consumers who only need a flat Grind Survival Knife can fix their blade with Kraton or Gritstone clay. These materials are fairly cheap and available at many craft stores and rock shops.

Alternatively, there are plenty of knives made with concave grins that offer more flexibility.

Less likely to accidentally cut yourself

A flat grind blade is much more likely to prevent you from cutting yourself because of the angles created by the curvature of the blade. A convex grind blade has more of a rounded profile due to the slope of the blade.

Convex grind blades are harder to put together and require more patience than a flat grind. This can be fun, but may take some time to learn. A patient knife maker can create beautiful knives in a short period of time!

When beginning your knife making journey, it is important to learn how to set up your workspace and how to make your first few knives. Set up can include getting a knife dry-fired, using an old book as a reference book, or taking up some new techniques and methods.

Better grip

If you are looking for an edge-blunting exercise, try a medium or even a fine grind on your blade. These will require more effort on your part, but provide better grip and control.

A flat grind blade has less geometry in the face of the blade. This means there is less control over how the knife turns in your hand. This lower control can be worse than having a hilted or unheated dagger in your grip!

The benefit of a fine or medium grind on a survival knife is for better stone flicking practice. You can use a slightly finer blade will give you better sweeping strokes which is great when hunting or fighting against greater size prey such as deer.

You can also use a slightly coarse blade for practicing sharpening stones to create deeper cuts.

Easy to sharpen

A flat grind blade is a nice benefit of a fixed blade survival knife. Many times, the concave shape gives you more depth of carry, making it useful in a emergency situation.

In this article, we will discuss how to proper sharpen the Christensen 2-3 ½” Closed Grind Survival Knife. This knife can be sharpened on the gas grinder or on the fine diamond stone. We will also discuss some tips for using the stone and how to maintain a better finish on the knife.

When using the gas grinder for sharpening, remember to keep your guard away from the edge of the grinder when doing so. Also, do not overdo it with the sharpening tool- you want a fairly blunt edge, but one that is still able to cut!

When using the fine diamond stone, remember to keep an even pressure on it and to remove any unwanted marks.

Suited for chopping

The flat grind blade on a fixed blade survival knife is an excellent fit for the type of blade you want. If you have a need for precise cutting, then a keenly serrated or sharpened edge will help you meet your need.

If you needed to use your knife in hard usage such as combat, then a heavier steel might be needed to withstand the stress of such usage. Since the flat grind blade is not especially suited for folding or serrated blades, this will keep the length of the knife intact while uses in combat or craft work.

Another benefit of a flat grind blade is that it makes it easier to handle. When cutting with a thin blade such as an ordinary paper cut, it can be tricky to keep one’s hand at the correct angle to the knife. With only one point of contact, this can lead to pain or injury.

Suited for piercing

The medium hollow grind of the blade allows for cutting through almost anything, making it a very versatile tool. When used in conjunction with the spine being flat and the rocker being slight, it makes for a very effective piercing tool.

Since the spine is only slightly convex, when you push against it with your finger, you can feel a slight shift in weight. This is what allows it to maintain its shape while being serrated along the rest of the blade.

When doing leatherwork or other leather crafts, you will need to buff your knife to bring out the colors. This is true even with a fixed blade knife!

I would recommend using an old grain whiskey or brandy to preserve the color of your knife.

Longer lasting blade

A flat grind blade on a fixed blade survival knife gives you more length to work with. This allows you to cut deeper, and stay sharp longer!

Aerodynamic blades bend more when they are severed, which forces some material into movement. When this happens with paper, it looks funny and changes the balance of the knife.

When using a flat grind blade on a survival knife, there are two main problems that can occur. The first is when the user cuts too hard, too fast and the knife overcuts. The second is when the user cuts too slow, or less than needed, due to the blade not staying sharp.

Aerodynamic knives move enough to change their balance when cut, which prevents either of these problems from happening.

Little to no blade wobble

A flat grind blade is what gives the Survival Knife its unique look. While a round grind blade would be more versatile and suitable for most purposes, a flat grind will give you more stability and less punishment on your opponent.

This property is what gives the blade its flatter look as it cuts. A round grind blade would tend to change shape slightly when cutting which could cause slight problems such as chip or burn formation or stickiness which causes the blade to rotate.

When looking at knives in the $25-$50 range, there are sometimes already flat grind blades included! If you are looking for more expensive knives, then might want to consider a convex grind knife with a flat top which gives more stability to keep your knife true and level.

Overall, if looking for a short survival knife, consider this type of blade! If looking for a folder type knife, consider this slimmer version.
