Explanation:

  • Scribers are used in metal-working,to mark lines on workpieces, prior to manufacturing
  • Finely tapered and fine point scriber tips will give a thinner more accurate scribe line, also it favors for scribing very close lines
  • But more fine tips wear quickly or require more frequent sharpening and may also break easily
  • So 12°-15° is more suitable.
