Application

Applications of Diamond Whetstone (Diamond Sharpening Stone)

Diamond whetstones deliver fast, predictable cutting and long-lasting flatness across a wide range of hard materials — from stainless and powdered steels to carbide, ceramics and glass. Engineered in multiple grit grades and bond types, they are ideal for rapid re-profiling, everyday edge maintenance, precision finishing and wheel dressing in kitchens, workshops, manufacturing lines and field-service kits. Choose coarse for stock removal, medium for bevel formation and fine/ultra-fine for polished, low-friction edges; the result is repeatable performance, reduced downtime and cleaner, safer cuts.


Primary application areas


  • Precision instruments & hobbyists: Model-making, surgical instrument maintenance, and other high-precision needs.

  • Kitchen knives (home & professional) — rapid edge maintenance, re-profiling and polishing of stainless and powdered steels.

  • Chef, butcher & food-processing operations — on-bench quick restorations to minimize downtime.

  • Cutlery manufacturing & sharpening services — repeatable bevel production and finishing in production lines.

  • Woodworking tools — shaping and sharpening chisels, plane irons, carving knives, and spokeshaves.

  • Garden & landscaping tools — sharpening shears, pruners, lawnmower blades and hoes.

  • Industrial tooling & metalworking — reconditioning HSS, carbide, shear blades, dies and punches.

  • Grinding wheel dressing & lapping — truing and dressing conventional grinding wheels and laps.

  • Glass, ceramic & hard brittle materials — chamfering, smoothing and edge finishing of glass and technical ceramics.

  • Scissors, razors & precision cutting tools — fast, controlled edge repair for scissors, straight razors and barber tools.

  • Surgical, dental & laboratory instruments — high-precision edges and repeatable finish for instruments.

  • Hobby, model-making & jewelry — fine shaping, bezel work, and delicate edge finishing.

  • Precision trades (watchmaking, optics, instrument making) — micro-finishing, de-burring and polishing small edges.

  • Field & maintenance kits — compact diamond stones for on-site blade repair and emergency reconditioning.

  • Deburring, chamfering & finishing — removing burrs and producing controlled chamfers on metal components.

FAQ

What are the two sides of a sharpening stone?

Whetstones, like other sharpening stones, usually feature two sides with separate grit: one coarse, and the other fine.   It's important to know that you're removing metal with each pass of the knife, so using the correct side for the job is a must.



Is diamond sharpening stone good?

Advantages of diamond sharpening plates: They allow quick removal of material for grinding out chips and changing the base bevel of plane irons and chisels.   Quick sharpening and material removal also in medium grit grades is another advantage.


What is the best diamond grit for sharpening knives?

For the first step in sharpening a very blunt knife, we recommend a coarse, 400-grit stone.   For the first step in sharpening undamaged and regularly maintained knives, stones with 800-2000 grit are a good choice.   For basic sharpening, it is best to use a 1000-grit sharpening stone.


Which side of sharpening stone is fine?

If your whetstone has a coarse and fine side, begin with the coarse side.  If you use two stones of different grit, start with the one with the lower grit number.  Hold the knife with the handle in your dominant hand.


What grit is a diamond sharpening stone?

Diamond Sharpening Stone Abrasion Rates

For larger surface areas or to flatten the back of chisels and planes, it is best to use a 600 or even 1200 grit diamond sharpening stone.
