How Can 21 AWG SS316L Flat Clapton Wire Be Cut Easily?

  2. Measure and Mark: Before cutting, measure and possibly mark the length you need. Ensuring you have the correct length will prevent wastage of material.
  3. Steady Hands: Hold the wire firmly but gently, ensuring it is taut and straight. Use your other hand to position the cutters at the spot you want to cut.
  4. Clean Cut: Apply a quick and decisive snip with the cutters. A swift motion ensures a clean cut without fraying or bending the wire unnecessarily.
  5. Inspect the Cut: Check the cut end to make sure it is clean and straight. If there are any jagged edges, you can use a small file or sandpaper to smooth them out.
  6. Safety Precautions: Always ensure you are cutting away from your body and wearing safety glasses to protect your eyes from any potential wire clippings.
  7. Clean Up: After cutting, ensure to collect and dispose of any wire clippings to prevent any safety hazards.
