Are you interested in understanding how spring assisted knives work and how they’re made? This comprehensive guide will walk you through everything you need to know about spring assisted pocket knives, from their mechanism to practical considerations. Whether you’re a knife enthusiast or simply curious about knife making, this article provides valuable insights into the world of assisted opening knives.
What Is a Spring Assisted Knife?
A spring assisted knife is a type of folding knife that uses an internal spring mechanism to help deploy the blade. Unlike an automatic knife or switchblade, a spring-assisted knife requires manual initiation to start the opening process. The spring mechanism takes over once the blade is pushed past a certain point, making it easier to open with one hand.
How Does Spring Assisted Opening Work?
The spring assist mechanism relies on several key components working together:
- A tension spring that stores energy
- A thumb stud or flipper for initial blade movement
- A locking mechanism to secure the blade
- A safety lock to prevent accidental deployment
When you push the thumb stud or flipper, the blade moves past a certain point, and the spring takes over to complete the opening process.
Legal Considerations Before Making a Spring-Assisted Knife
Before attempting to make or modify a spring assisted knife, it’s crucial to understand:
- Local laws regarding assisted opening knives
- Differences between spring assist and switchblade knives
- Restrictions on blade length and style
- Regulations about carrying and selling these knives
