Very useful #400 grit diamond stones for coarse sharpening and, crucially, for lapping and flattening your waterstones. An adhesive layer of monocrystaline diamond chips is backed onto a 10mm thck block of aluminium giving a solid, stable and flat product.

Always use wet, and work gently. For lapping, smooth off wetstones in a circular, figure-of-eight action.

  • #400 grit
  • 21 x 7.5 x 1cm

Niwaki Tip: A great solution for flattening your stones.
