When it comes to pocket knives or any small handheld tool, spring loaded knives undoubtedly hold a prominent position. They become more practical and efficient in situations where one needs swift access to a blade. However, like any other tool, they are prone to wear and tear, and may require regular maintenance or in some instances, repair. Rather than opting for an expensive replacement, wouldn’t it be easy if you could give your favorite spring loaded knife a new lease on life? If you’re a tool enthusiast interested in doing the repairs yourself, this blog post will provide a detailed step-by-step guide on how to fix your spring loaded knife.
A Sneak Peek into How Spring Loaded Knives Work
Before diving directly into the repair process, it’s crucial to understand the mechanism behind the spring loaded knife which mainly relies on the ‘Button Lock’ system. Essentially, it’s a type of lock that uses a spring release mechanism to allow the knife’s blade to swiftly move out of the handle.
Understanding the Components
What Makes Up Your Spring Loaded Knife?
A spring loaded knife essentially consists of four primary components:
- The Blade: This is the part you use to cut or slice whatever it is you’re working on.
- The Handle: It’s the part you hold while using the knife. Quite often, the handle will house the spring mechanism.
- The Spring: Usually a coil spring, it’s the part that quickly pushes the blade out of the handle.
- The Button: Lastly, there’s the button which is pressed to release the spring mechanism, allowing the blade to flip open.
Common Issues with Spring Loaded Knives
While rugged and reliable, spring loaded knives can suffer from any number of issues. Some such issues include a blade that won’t lock properly, a jammed button, spring failure, and more. Each of these issues can prevent the knife from functioning correctly, potentially causing harm, or at the very least, inconvenience during usage.
Fixing a Spring Loaded Knife
Now we’ve arrived at the crux of the matter – fixing your spring loaded knife. Repairing it involves disassembling, diagnosing and fixing the specific issue, and then reassembling the knife.
Step 1: Disassemble the Knife
To disassemble the knife, first ensure the knife is in its closed position. Using a screwdriver, remove the screws from the knife handle and gently separate the two halves of the handle. Take care not to lose any small springs, screws, or other components that may be housed within the handle.
Step 2: Diagnose the Issue
Identify the problem component. It could be the spring, the button, the blade or even the handle. Look for signs of damage or wear and tear.
Step 3: Repair or Replace the Component
Once you’ve figured out the problem, it’s time to address it. Sometimes, all that’s required is a good cleaning. Accumulated dirt and grime can affect the functionality of a spring loaded knife. If there is an actual damage to a component, you have the option to repair it (if possible) or replace it.
Step 4: Reassemble the Knife
After the issue has been addressed, it’s time to reassemble the knife. Carefully fit all the pieces back together and secure it by replacing the screws.
A Guide to Fixing the Common Issues
Different problems will require different solutions. Here are guides for fixing some of the most common issues.
