Fine tuning: adjust spring

The spring should lie flat in the handle when the blade is both open and closed, so with the blade open clean up the top of the handle at the bolster end, taking care to file the spring completely flat to the liner:

Then close the knife

If the spring sits lower than the bolster -

• take the blade out and remove a little material from the back square:

• put it back together; the spring should now be low when the blade is both open and closed
• with the blade open file the top of the knife flat again and it should now be flat when both open and closed

If the spring sits higher than the bolster -

• take the blade out and remove a little material from the kick and walk

• put it back together; the spring should now be flat both open and closed
