The 1x4 Suehiro 180 GC grit is an aggressive, extra coarse stone used for serious profiling, repairs, and initial sharpening. This is an all-around workhorse stone that removes metal quickly while leaving a finish that is easily cleaned up on subsequent grits in your progression. This stone can also be used in place of extra coarse and coarse plates.

This stone is 1" x 4" in size mounted to an aluminum blank with a total thickness of 5-6mm and used with water only. It works best when soaked in water for a minute or two before use. Let air dry and store dry when not in use.

Abrasive Material: Silicon Carbide

Ideal place in a sharpening progression:

  • Starting grit for major repairs and profiling.
  • Starting grit for initial sharpening and maintenance
  • In place of extra coarse and coarse diamond grit plates.
  • Where mechanized sharpening and belt grinders are not available.
  • Before progressing to another coarse or lower end medium grit stone (120-1K grit)

The Suehiro 180 GC sharpening stone is an economical extra coarse grit sharpening stone that works on almost all types of knives, scissors, tools and chisels, including those made with abrasion resistant steels. While the 1x4 size is meant for use with the KME Sharpener, it is also a great size for a slip stone, field stone or a pocket stone for knife repairs and sharpening on the go, or to remove unwanted burrs.

On More Traditional Carbon Steel and Stainless Steel Edges the Suehiro 180 GC works on steels between RC 52 and RC 65 on the Rockwell C Hardness scale. The stone itself is very aggressive and releases a lot of grit for extra punch. It does make quick work of seriously reprofiling and repairing of the softer end of the spectrum of most steels used by many kitchen knife makers like Henckels, Wüsthof, Gunter Wilhelm, F Dick, Victorinox, etc. and steels like X50CrMoV15, AUS6, 440B. 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, 440C, 52100, Aogami White, O1, Shirogami Blue, W1, etc. The Suehiro 180 GC is probably the lowest grit you would need for any repairs. The softer matrix of this stone really reacts well with the harder RC steels and leaves an edge that is prepped for further cleanup by finer grits.

On Carbide Forming Steel and More Abrasion Resistant Steel Edges such as D2, M2, S35V, S90V, VG-10, etc., The Suehiro 180 GC excels at removing matrix steel and carbides. The abrasive release of the stone while in use add to its aggression and can cut as fast as most diamond plates and can be used to “save” your diamond plates from unnecessary wear, especially on the abrasion resistant steels. It also leaves the surface of the blade prepped for further refinement.

Hacks and Tips:

  • This stone makes its own slurry as it is used and is a little thirsty. Keeping the stone viscous with water will keep it more aggressive.
  • To clean up the scratches before moving to another grit, let the paste on the stone dry out slightly. This will leave a slightly less scratchy finish in preparation for the next grit.
  • This stone will dish with use. Lap this stone with an extra coarse diamond plate, silicon carbide (SiC) powder, or very low grit wet dry sandpaper to keep it consistently flat and clean.
