Ease of Operation

Although Leatherman has produced efficient and highly functional multi-tools over the years, they have sometimes received complaints from users about the tools in a multi-tool being difficult to access. You don’t need to worry about that with the Leatherman Free K4X EDC as Leatherman has taken this issue into account in the K series. They have ensured that anyone can open it easily with just one hand without breaking a fingernail by simply removing the nail nicks. Moreover, all tools are accessible from the outside, which means that you won’t need to open the entire gadget no matter which tool you need.

Revolutionary Magnetic Technology

Another improvement on the design offered by Leatherman in the K4X pocket knife and multi-tool is the new magnetic technology that they have introduced in their Free collection. This feature promotes the smooth opening and closing of the tools. Leatherman claims that this feature will increase the multi-tool’s life span even further because it reduces friction and prevents wear and tear.

New Locking System

Leatherman has also incorporated a new locking system in the K4X EDC pocket knife, which means that this multi-tool is more durable compared to its predecessors. This new locking system, coupled with elastomer springs, reduces friction and makes the multi-tool sturdier. This lock is also accompanied by a clicking sound which signals to the user that the tool has been locked in place and can now be used with full confidence.

Removable Pocket Clip

If you want to carry your pocket knife multi-tool around, then Leatherman’s K4X EDC comes with a removable pocket clip that can easily fit into your pocket.

25-Year Warranty

With all the new features added in this multi-tool that reduce friction and wear, there does not seem to be a need for a warranty, but Leatherman still provides the standard one for 25 years. This reassures the users about the durability and longevity of the product.

Pros & Cons

  • Lightweight and durable
  • Single-handed and outside access guarantees an easy operating experience for users
  • New magnetic technology makes it easy to smoothly open and close
  • Well-made safety lock that reduces friction even further
  • 25-year warranty
  • Overpriced compared to its quality
  • Some users find the knife to be too large in size

Leatherman Free K4X Review – Conclusion

The Leatherman Free K4X EDC pocket knife and multi-tool offers an incredible package that includes a sharp knife and 8 other different tools that can be used for daily tasks. This multi-tool is meant for anyone who likes having a pocket knife but would also want some extra tools.

Its current competitors are the P series and the T series in the Free Collection. The P series are more expensive, but that is also because they are a newer version of Leatherman’s classic multi-tool. The only real difference between the P series and the K series is the inclusion of pliers in the former. On the other hand, the T series are cheaper than the K series and are a lighter version.

You should buy the Leatherman K4X EDC pocket knife and multi-tool if you are interested in carrying a sharp pocket knife with cutting edge efficient tools. The final decision rests solely on you. However, we like this multitools.
