The Types of Knife Blades

Choosing the type of knife blade for your next pocket knife can be overwhelming. After all, there are many different types of knife blades on the market. Choosing the type of knife blade is very important when selecting the best pocket knife for your requirements. You should make sure that the style and design of the blade will suit your intended use for the knife. Most knife manufacturers modify their own blade designs and these variations are designed to add a little something extra to the knife. However, all of these variations originate from the basic blade styles and in this article we will focus on the most popular basic blade styles used in pocket knife construction.
The types of knife blades

1. Straight-back blade

This is the standard type of blade found on many knives. It features a flat back (which is dull) and a curved edge. It is a good knife for chopping and slicing, and is most commonly used for kitchen knives. The straight dull back of this knife allows the user to put extra pressure on the knife to increase the cutting force. These blades are quite heavy when compared to other types of knife blades.

2. Drop-point

This type of blade is most commonly used for pocket knives and most modern manufacturers are using a modified drop point blade (the Spyderco Tenacious is a good example of a manufacturer modified drop-point blade). This blade features a convex curve on the back of the knife towards the tip. It is a very popular type of blade because it can be used for most cutting applications. Its only real weakness is that it is not as suitable for piercing as some other knife blades.

3. Spear-point

This is a symmetrical blade that finishes in a sharp point at the tip of the blade. They can be sharpened on both edges or have just a single edge. This type of knife blade is common for penknives, daggers, and any knife that is designed for thrusting or throwing.

4. Clip-point

A clip point blade is the same design as a straight back blade, but has a section of the blade removed from the back. This gives this type of blade a thinner tip, which is perfect for cutting in hard to reach places. The tip of these knives is usually concave, but straight tips are also quite common.

5. Tanto

This blade takes its name from Japanese samurai swords (tanto was the word used for the tip of a broken samurai sword). It has a chisel edge and this provides excellent strength. They are not overly suitable for slicing, but the tremendous strength in the tip of this type of blade is perfect for penetrating. This type of blade is not overly common for pocket knives, (although the popular Benchmade Griptillian offers a tanto blade option), but it is becoming popular in the tactical knife market.

Pen blade

The pen blade is very similar to the spear-point blade, but it has a much more gradual curve. They are most likely to be sharp on one side and dull on the other. This type of knife blade is very popular with Swiss Army knives and similar types of penknives.

Choosing the type of knife blade really comes down to your own needs. It is important to consider what you will be using the knife for and then pick a blade that is suitable for these applications. Unfortunately, there is no single knife blade to suit every situation, but if you are really unsure then a drop point blade is a good place to start.
