• Internal mechanism automatically strikes a
  blow when downward pressure is applied
• Adjustable knurled cap regulates the
  force of the blow
• Spring tension, which regulates the blow,
  is constant so marks made by the point are
  uniform in depth and size for each setting
• All sizes are identical in style, differing
  only in the striking power
• The point can be easily removed for
  regrinding or replacement
• Heavy-duty 18C is capable of striking a
  much heavier blow than the other sizes
