Knives out! How to choose the right folding knife to suit your adventure needs

This may sound Ramboesque, but having a folding knife clipped to your pocket is vital when outdoors.

It is discreet, lightweight, pocketable and super useful, even when you already have a machete on your belt while camping.

It has become so useful that many people treat folding knives as an everyday-carry, keeping one in the pocket everywhere they go.

When choosing the ideal folding knife, there are many factors to consider – the design, material, lock type, method of deployment and price.

One important aspect which is often overlooked is the pivot. This is one of the most critical parts of the knife that allows the blade to be opened and closed smoothly and securely.

The pivot is the axis of rotation of the blade in the folder and ensures that the blade will swing out without hassle. The pivot must have a pair of washers made of brass, copper, Teflon or ball bearings.

The ball-bearing pivot is a relatively new innovation which uses precision-engineered ball bearings that are smaller than sesame seeds, made of steel or even ceramic in higher-end models.

Their most significant plus point is that they make the blades open and close with a silky smooth flip, often with just a twist of the thumb or flick of the index finger. This is particularly important in tactical use or during emergencies when speed and ease of use are critical.

Ball-bearing pivots are durable. The bearings distribute the load evenly across the pivot, reducing wear and tear and extending the knife’s service life for years.

They improve lock-up too, helping to prevent the blade from developing any side-to-side play or blade wiggle after a few years of use.

However, before rushing to include such a folding knife into your ensemble of outdoor gear, consider the disadvantages.

Ball-bearing pivots are more complex than other pivot types, which can make them more challenging to manufacture and repair. This makes them costlier, with potentially long waiting times for repairs or replacements.

Knives like these also tend to be a little heavier, which may not suit those who prioritise lightweight-carry, such as those who backpack their way up a mountain.

These knives can be challenging to clean and maintain. Dirt, grit, even the lint from your pocket can cause the pivot to become “sticky”. Cleaning or repairing it may require special tools or skills.

They can fail. The bearings can be damaged or misaligned after hard use or when carelessly neglected in saltwater environments, for example. They tend to be more expensive because of the greater degree of precision engineering involved.

That said, every piece of outdoor gear has its own inherent pros and cons, so it depends on where you are going and what you are doing.

Top-shelf folding knives with ball-bearing pivots can cost over RM1,000, and you can be sure they are made with premium materials that can withstand the elements and hard use, while giving you smooth deployment of the blade every time.
