4 Comparing factors of Frame Lock vs Liner Lock

So, let’s now look more closely at the 3 major comparing facts and figures to evaluate which one of them is better. We shall judge their material, handle, sharpness, durability, locking mechanism, and price one by one. 

1 .Material Handle and Design

Material:  It is unnecessary to mention here that material is of utmost importance to manufacturing any sort of equipment. High-quality materials give the product a solid strength and the ability to work better.

Frame lock knives, also known as Skinlock, are usually made out of Titanium slabs. This 3-milliliter slab layered and coated with flax fiber over it. The layer is not a thicker one; yet, it makes the knife thick enough to be flexible. It gives an aesthetic look as well.

On the other hand, Liner lock knives are mostly made of Titanium and steel alloy. And there are no such coatings to strengthen the knife in liners. However, it doesn’t make the liner fragile and brittle.

Handle: On the first look, you may not find any difference in the handle structure of both knives. However, there are a few simple disparities. 

In frames, Titanium made handles are traditionally designed. It may be a comfort for many. Liners look almost the same; but they are more steely. So they are good for hunting purposes.

Design: There are no big differences in the designs of both knives apart from the fact that liners come with a wide range and varieties to choose from.

2. Sharpness and Durability

Knives are meant to be sharp. Pocket knives need to be edgy and keen as well. These two types are not as sharp as kitchen knives, but they are sharp enough to be your campaigning companion. 

Both knives have near equal sharpness. But frame locks are more durable due to its better layering. However, it should be remembered that sharpness and durability walk through the opposite roads. So if you happen to meet one, you’ll surely miss the other.

3. Locking Mechanism

Here comes the most subtle and important part of a pocket knife: the locking process. If it works properly, the knifesmith of a particular knife can be declared excellent.

The locking mechanism of frame lock is such that a portion of frame will be engaged to lock the knife’s blade. So the frame itself bent to give hardiness to the pointing blade. 

Contrarily, the liner locks usually have a small liner to support the underneath of the blade during its projection. But these knives use spring bars to prevent them from being closed suddenly. It works, but makes it vulnerable in long-term usage.

As far as the locking and closing procedures of both types are concerned, frame locks can be a better choice since it won’t be easily closed due to excessive pressure. Despite having the same outward appearance, the frame has more inner strength. But it makes the knife a bit heavier and it is prone to closing with a bit of hassle.

4. Price Evaluation

Budget is a significant matter before choosing any product, especially Frame Lock vs Liner Lock. So the price of a knife is crucial for many. And the money you will spend is worth spending or not is a matter of consideration as well.

Frame locks offer from low to high budgeted knives. Kershaw flippers are most common in frames due to their mediocre price. It also offers Zero tolerance flippers of high-quality knives at an expensive price. Interestingly, they have lower priced knives as well.

On the other side, liners are generally of mediocre budgeted knives and their products are quite affordable. Spyderco is most common among them. So, the liner is budget-friendly and the frame is, because of the quality, a bit pricey.

This knife can be used in one hand due to its secure and smooth opening and closing. The specifically designed torsion bar attached in the frame itself moves and locks the blade to avoid any unexpected closure. And you know perhaps, unnecessary closures can be dangerous.

The handle provides enough grip and the chance of slipping or missing any cut is likely not to happen. Kershaw designed the frame lock with two identical metal pieces on both sides of the blade. While opening you the metal automatically moves to prevent closing. To close it, you need to push the side frame to allow the blade to be folded into the handle.
