(18) Most of the micarta is removed, leaving only the spine
(19) Punching out the nylotron washers
The handle begins to really take shape as we grind the sandwich according to the outline drawn on
the scale (17). We now have something that feels like a knife handle but it's solid - no room to
put the blade inside. Using the blade as a guide we cut away all the micarta except the part that
contains the screw holes for the back of the handle - the spine (18). At this point the blade can
be mounted inside the handle but it is a very loose fit. That's because the blade is about 1/8th
inch thick and the spine was 3/16ths. In picture (19) you see the very manual process involved in
punching out the nylotron washers that will fill the gap and take up the slop. It is desirable for
the washers to be as thin as possible, and in fact, they are only about .010 thick. This means that
even after the washers are added there remains a bit of slop that is the difference between the
thickness of the blade plus the two washers and the thickness of the spine. After a little arithmetic
and careful measurment the thickness of the spine is reduced to match. The result is that everything
stays parallel and the knife stays thin.
