Step    4a: Begin   the First   Stroke. Hold    your    knife   with
the  blade   edge    pointing    away    from    you.    Place   the
heel    of  your    knife   on  the far edge    of  the stone   and,
holding the blade   gently  but firmly  with    both    hands
at  a   15- to  20-degree   angle   and using   even    pressure,
slowly   drag    the     knife   over    the     stone   toward  you
down     its     length  while   simultaneously  moving  the
knife   so  that    the contact point   moves   toward  the tip
of  the blade.
Step    4b: Maintain    the Angle.  Be  careful to  maintain
the  15-     to  20-degree   angle   as  you     pull    the     knife
across  the stone.  Pressure    should  be  firm    but gentle,
and the blade   should  glide   smoothly    across  the stone.
Step    5:  Repeat. Each    stroke  should  finish  with    the tip
of   the     knife   touching    the     bottom  edge    of  the     stone.
Lift     the     knife,  reset   the     heel    at  the     top     edge    of  the
stone,  and repeat.
Step     6:  Look    for     Silty   Water.  As  you     repeat  the
process,     a   thin    film    of  silty-looking   water   should
collect  on  top     of  the     stone   and     on  the     blade. This
abrasive     liquid  will    gradually   take    material    off     the
edge    of  your    knife,  sharpening  it.
Step    7:  Check   for Burr.   As   you     continue    to  repeat
strokes on  the first   side,   a   tiny    burr    will    eventually
form    on  the other   side    of  the blade.  To  check   for it,
place   the blade   on  your    thumb   and pull    it  backward.
If  burr    has formed, it  should  catch   slightly    on  your
