Best Folding Knife: Top Reviews & General Information You Should Know

Best Folding Knife

A folding/tactical knife is a cutting tool that has a pivot system installed on its body, which allows it to fold. Since the market is quite rich in offers, there are various types of tactical knives, including: linerlock, lockback, frame lock and slip lock. All these models are actually named based on the locking system when the blade is in use, but the general design is almost the same.

If it were to discuss the best folding knife, the basic structure should have the following parts:

  • pivot,
  • lanyard hole,
  • handle,
  • bolster,
  • flipper ricasso,
  • primary grind/ bevel,
  • secondary grind/ bevel,
  • swedge/ false edge,
  • thumbstud,
  • thumb ramp.

But, before we discuss specific models and their benefits, let’s first take a look at the main types of folding mechanisms and the main features one should consider when purchasing such a knife.

Types of locking mechanism

Lockback mechanism

A lockback knife is defined by a blade that locks in the open position. A locking folder normally provides the firm support so when you open the blade, the rocking plate, which is visible from the back locks against the blade. To close the cutting edge you simply have to push down the rocker positioned at the back of the handle.

Lockback mechanism

Usually, this mechanism needs two-handed closing, even though there are some models that can be close with a single hand. Knives with this locking system are among the most popular and most resourceful cutting tools to engage.

Liner lock mechanism

A liner lock knife uses a side-spring lock that allows you to open as well as close it with one hand. The basic structure of a liner lock consists of the following parts:

  • stop pin,
  • detent ball,
  • liner lock face,
  • blade lock face,
  • blade stop pin cutout,
  • blade bevel,
  • blade edge,
  • thumb button,
  • back-spacer,
  • lanyard hole
  • detent hole.

This locking machinery is a falsely simple yet very effective method of securing a folding blade in the open stance.

Liner Lock knife mechanism

There no moving parts therefore it does not need a very precise fitting. This system is not only easy to clean, but also does wonders in the most awful conditions of dust, mud, and dirt.

Slip lock mechanism

A slip lock knife employs a different kind of system; where the blade does not lock open. Instead, it is held in position by a back spring, which allows the edge to open/close depending on the applied pressure. This kind of locking system is found on designs of most old-style pocket knives, but the system can also be found on other knife types in the market.

Slip lock mechanism

A dagger with this kind of locking is very convenient. A spring will rarely gridlock therefore there is no instance in time when you will experience malfunctioning. In fact, blades under this category are highly resourceful and versatile for fast release and cut.

Frame lock mechanism

A frame lock knife operates in the same manner as a linerlock, but it makes use of a part cutout of the main handle. The frame lock, moves into the handle opening and then locks against the frame when the blade opens. This is one of the best locking systems with the best safety measures and you can use it with either your right or left hand.

Frame lock mechanism

The stiffer joints are well-designed to ensure that you are always safe from accidental closures. You should not be worried about failure because the thickness of the locking bar provides good strength as well as security.

Other locking systems that are used include: Ark lock, ball bearing lock, pick lock, collar lock and tri-ad lock.

How to choose a folding knife

There are three primary features that you need to examine when choosing folding blade, including: locking mechanism, the blade, and ergonomics. As mentioned above, there are various ways of securing an open blade and all the locking systems are effective in one way or another.

Folding_knives and lock mechanism

The blade is one of the most important parts of any cutting tool. Therefore, your choice should be nothing but excellent. You need to choose a blade design that suits your needs and you need to take the following parts into consideration: swedge, primary bevel and secondary bevel. A good locking dagger should be able to deal with a cutting blow and a penetrating blow as well. Cutting depends on the sharpness as well as the curve of the cutting edge so, choose an edge with your desired tip and belly shapes.

The blade thickness should go hand in hand with your cutting activities. Keep in mind that a thinner edge will cut with minimal effort compared to a thicker one but, if you are seriously planning to use your knife in harsh conditions, then it is wise to choose a thicker edge.

Folding knife

Ergonomics is one factor you should always consider as you need a knife that feels comfortable to handle and use. Therefore, the whole thing needs to feel natural – it should be an extension of your arm. The handle should be fitted with curves that match up to the shape of your grip.

  • I use my SOG Flash II knife everyday and like the easy, strong, and quick assisted open. However, you do need to push it against another object or use your other hand to help close it. You will also need to break in the blade lock release a bit. The knife is light, and can comfortably hang inside your pants pocket. It is also easy to pull out and open for use which makes it a great EDC for protection.

  • I purchased the BlizeTec Survival Knife because of its lifesaving features (seat belt cutter, glass cutter/window breaker). I have given this as a gift to relatives and close friends and recommended they keep it inside their cars’ glove compartments. The knife’s high quality blade makes it a great camping and hunting knife.
