(21) The lock, blade stop, and ball detent in place
(22) The pocket clip
With the blade in place we can do the final profile grinding of the handle so the the handle
precisly fits the blade. This gives us a handle with a working blade that won't lock into
position. Picture (20) shows the locking bar being cut free from the liner. The result can
be seen in picture (21). Once the lock is adjusted so the blade is in the correct position
we need a stop bar so that the blade cannot stops exactly at the full open position. This
bar and also the ball detent can be seen in picture (21). The ball detent is at the end of the
locking bar (very small). It's a steel ball bearing the mates with a dimple in the blade to
help keep the blade from coming out of the handle when the knife is closed.
The processes for adjusting the shape of the locking bar where it meets the blade, positioning
and mounting the locking bar, and for matching the ball and detent are all critical and very
time consuming. As such, they are beyond the scope of this discussion - please accept that
they get done and my hair gets grayer.
The final part to be added is the pocket clip (22). I mill a pocket into the handle to seat the
base of the clip flush with the surface of the handle because it's flatter and because it's classy.
