One of the main components of any knife, is its blade. Therefore, when shopping for one, you must compare different types of knife blades, so that they serve your purpose well.
Most blades are made from steel.
It dictates how the blade will perform any cutting task.
As you might know, steel is an alloy, which means it is made up of iron and carbon. The iron sometimes has other components in the mixture to augment its performance and durability.
5 Properties Of Knife Blades
Manufacturers of knives, produce these implements with different mixtures added. Even the finishing style of how they roll and heat the blade, can vary.
In the end, the diverse kinds of steel employed when creating a knife, all demonstrate different degrees the five properties identified below.
Hardness Of Knife Blades
This is the capacity of the knife blade to defy deformation if it comes under applied forces and stress. How hard the knife steel is dependent on its potency in addition to the Rockwell C scale (HRC) measurement.
Toughness Of Knife Blades
This is the capability of the knife blade to defy being cracked or chipped if it suffers brunt force hits.
The worse thing that can happen to a knife blade, is chipping. It is not easy to remedy this issue.
Toughness can be measured through different ways. As such, it has a less dependable testing criteria than testing for the hardness of a blade. However, it is important to note that a knife blade steel cannot be too tough, else it is more likely to chip.
Wear Resistance Of Knife Blades
This is the capability of the knife blade to endure dents, breaks and scratches from both uncompromising and adhesive wear.
The former happens when more durable or inflexible particles go over more pliable surface. On the other hand, adhesive wear can happen, if debris is lodged anywhere onto the knife blade surface.
Wear resistance normally associate with the hardness of knife blades. However, it can be affected by the explicit chemistry of the steel.
When steels are equally hard, the one with larger carbides usually withstands the rigor or wear much better. Though, it is important to note that the carbide component can become brittle and crack.
Corrosion Resistance Of Knife Blades
This is the capability of the knife blade to stand up to rust or corrosion is important. Knife blades usually come in contact with corrosive elements such as salt, moisture or humidity.
The more resistant it is though, the less functionality or sharpness you will get from the edge.
Edge Retention Of Knife Blades
This is the capability of the knife blade to remain sharp. Especially when it is used constantly and for a long period. Edge retention is a mixture of the knife blade’s ability to not deform under pressure and also not wear down.
Different Types Of Knife Blades
Numerous types of knife blades exists. Today, we will explore several of them, which are more popular. They are utilized more commonly for production knives.
A lot of them are altered, depending on the knife manufacturer.
Normal Knife Blades
This kind of blade is simple. There is often a curved edge and a dull flat back. The normal knife blade isn’t extremely sharp. This blade requires extensive pressure from the user to amplify the cutting force. Users can rely on it for the purpose of slicing or chopping.
However, because of its dull back, you can use your hand or fingers to apply the added pressure required. It is also a heavier knife.
Clip-Point Knife Blades
This kind of blade is derived from a normal blade, however, the back is clipped, giving it a thinner knife blade.
That provides the knife with an additional function of reaching and cutting difficult places. It also gives the handler more control.
One type of knife that has this kind of blade is the Bowie knife. Sometimes the clip point knife blade is straight, instead of concave shaped.
Drop-Point Knife Blades
This kind of blade has a convex curve at the rear of the knife next to the tip, unlike a concave curve found on the clip-point knife.
It avails more strength than the other type of knives and efficient whenever used. A number of contemporary pocket knives use this shape of a knife blade.
Spear-Point Knife Blades
This kind of blade is balanced and comes with has a curve both sides of the blade. This means they have the capability to be sharpened on either side. You will see this design often on pen knives
In general, this design is also included on thrusting implements like daggers.
People love intrinsic designs or they may prefer a simpler version, so manufacturers will augment the knife blades to suit their clientele.
Regardless of that fact, the popular types are made from some of these knife blades.
