HAKUTO 1 #200

  • The first step in establishing bevel geometry for extremely dull and or damaged edges

  • Removes metal fastest

  • Chip removal

  • Removes low spots quickly

  • Ideal for heavy repair work

  • Optimal for foundation work and setting geometry

​​​

POINT

  • Generally used for fast removal of steel

  • Great for the removal of minor chips

  • Great thinning and setting edge geometry

  • Performing Metate periodically restores the aggressive cutting performance of the stone.

     Please watch the video on Metate instructions for #200 stone

 

HOW TO PERFORM FLATTENING AND RESURFACING OF 200 GRIT STONE

  • The first step in establishing bevel geometry for maintained but dull edges

  • ​Removes 200 grit scratches

  • Good for minor chip removal / bevel sharpening

POINT

  • Maintenance of the stone's surface during the sharpening process helps to keep the cutting speed of the stone at its optimal level

  • It's important to keep monitoring the flatness of the stone's surface, especially for heavy sharpening like thinning and repairs etc.

  • Please watch the video on stone maintenance

      for stones up to 1500 grit stone

ADVANCED SHARPENING
