If your folding knife is jammed and won't open or close properly, there are a few steps you can take to try and fix the issue. Here's a general guide to help you troubleshoot and potentially resolve the problem:
Check for debris: Inspect the knife's pivot area and the blade for any debris, dirt, or grime that might be causing the jam. If you see any foreign material, carefully clean it out using compressed air, a soft brush, or a cotton swab. Avoid using excessive force to prevent any damage.
Apply lubrication: Folding knives often have pivot points that benefit from occasional lubrication. Use a drop or two of light machine oil or a specifically designed knife lubricant at the pivot area to help the blade move smoothly. Open and close the knife multiple times to work the lubricant in.
Use gentle pressure: When trying to open or close the knife, apply gentle and even pressure. Avoid forcing the blade as this may exacerbate the problem or potentially cause damage to the knife.
Inspect the spring mechanism (if applicable): Some folding knives, particularly assisted-opening or automatic knives, have spring-assisted mechanisms. If the knife uses a spring, check to see if it is damaged or misaligned. If there's an issue with the spring, it's best to have the knife repaired by a professional.
Check for bent parts: Carefully examine the knife's blade, pivot, and locking mechanism for any signs of bending or misalignment. If you notice any bent parts, it's crucial to have the knife repaired by a professional to ensure it functions safely.
Disassemble and reassemble: If you are familiar with the inner workings of the knife and have the appropriate tools, you may consider disassembling the knife to identify the issue. Be cautious when disassembling and keep track of the parts. Clean each component, remove any obstructions, and reassemble the knife carefully. If you're unsure about this process, it's better to seek assistance from a professional.
Seek professional help: If the knife remains jammed despite your efforts, or if you're uncomfortable trying to fix it yourself, take it to a professional knife technician or a reputable knife repair service. They have the experience and tools needed to diagnose and fix the problem safely.
Remember that safety should be a priority when handling knives. Always exercise caution and avoid any actions that could cause injury to yourself or others. If in doubt, seek professional assistance.
