1x6 Jende 120 Diamond Stone Plate

AvailabilityIn stock

The 1x6 Jende 120 Diamond Stone is an aggressive, extra coarse diamond plate used for serious profiling, repairs, and initial sharpening. Diamond abrasives at this level stay flat their entire lifespan, and don’t shed abrasive or hog water. They cut very quickly and efficiently, and are the best all-around replacements for the coarsest synthetic and natural stones.

The Jende 120 Diamond Stone Plate is a premium extra coarse grit sharpening stone at a mid-range price that works on almost all types of knives, scissors, tools and chisels, especially those made with abrasion resistant steels. While the 1x6 size is meant for use with the Jende JIGS for Knives, Edge Pro, Hapstone and TSProf sharpeners, it is also a great size for a slip stone, field stone or a pocket stone for knife repairs and sharpening on the go.

1" x 6" x 5mm in size and mounted to a steel blank, The Jende 120 Diamond stone works best with water, but can also be used dry or with oil. Clean or rinse after use, and store in a dry place in between use to prevent any oxidation on the metal matrix.

Abrasive Material: Diamond Electroplate

Ideal place in a sharpening progression:

  • Starting grit for major repairs and profiling.
  • In place of or before any coarse synthetic or natural stones.
  • Where mechanized sharpening and belt grinders are not available.
  • Before progressing to another coarse or lower end medium grit stone (120-1K grit)

This diamond plate can also be used in a mix and match progression of other synthetic and natural sharpening stones, as well with other brands such as Shapton, Sigma, Suehiro, Imanishi, Spyderco, King, etc.

On More Traditional Carbon Steel and Stainless Steel Edges the Jende 120 Diamond Stone Plate works on all steel hardness on the Rockwell C Hardness scale. The plate itself is very aggressive, and makes quick work of seriously reprofiling and repairing of the softer end of the spectrum of steels like X50CrMoV15, AUS6, 440B, and most steels used by many kitchen knife makers like Henckels, Wüsthof, Gunter Wilhelm, F Dick, Victorinox, etc. This is also a stone that can be utilized on softer steeled garden tools such as lawnmower blades and hedge clippers and other tools that don’t necessarily need to be as refined in sharpness as they need to be shaped well for cutting at speeds.

On the higher end of the hardness spectrum of traditional steel edges made with steels like 1095, 52100, 440C, Aogami White, Shirogami Blue, O1, W1, etc. The Jende 120 Diamond can be almost overkill, and depending on the brittleness, may cause slight microchipping that will need to be worked out with a finer diamond plate or synthetic or natural stone. It is, however, the lowest grit you would normally need.

On Carbide Forming Steel and More Abrasion Resistant Steel Edges such as VG-10, D2, M2, S35V, S90V, S110V, etc., The Jende 120 Diamond Plate excels at removing matrix steel and carbides. Diamond abrasives cut everything like butter. One thing to watch out for is getting into a “rut” since the diamond do cut so quickly. Changing up the scratch direction keep the diamond plates from bottoming out.   

Hacks and Tips:

  • Keeping the stone clean and hydrated with water will keep it more aggressive.
  • Change scratch directions as you sharpen to keep the stone from bottoming out.
