The 1x4 Naniwa Chosera 2K Grit stone is an excellent stone for light touching up and routine maintenance on dull, but otherwise intact, edges. It leaves a very respectable and functional work sharp edge that is more than acceptable for almost any knife or tool. This stone cleans up scratches from most lower grit waterstones and from finer diamond plates and stones. It is a very good stone to finish on or to use as a medium grit stone before progressing to finer grits. 

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: Aluminum Oxide

Ideal place in a sharpening progression:

  • Starting grit for light repair and maintenance of an already sharpened but dull edge.
  • After higher diamond grit plate or stones to clean deeper scratches.
  • After lower grit sharpening stones (220, 320, 400, 600, 800, 1K, 1,500 grit)
  • After medium belt grinder grits (400, A30, A15 Trizact grit)
  • Before progressing to a finer medium grit stone and/or a lower grit polishing stone (3K - 8K grit)
  • A final stone for respectable sharpness on many knives and tools.

The Naniwa Chosera 2K sharpening stone 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.

This stone can also be used in a mix and match progression with other synthetic and natural sharpening stones as well as with other brands, such as Shapton, Sigma, Suehiro, Imanishi, Spyderco, King, etc. Naniwa Choseras are Waterstones but can be used in conjunction with oil stones (such as Norton India and other carborundum and Arkansas stones) if the blade is wiped clean before and after switching stone types. 

On More Traditional Carbon Steel and Stainless Steel Edges, the 2K Chosera stone works on steels between RC 52 and RC 65 on the Rockwell C Hardness scale. On softer end steels such as X50CrMoV15, AUS6, 440B, and most stainless steels used by many kitchen knife makers like Henckels, Wüsthof, Gunter Wilhelm, F Dick, Victorinox, etc., this stone easily maintains and sharpens, leaving a superior working edge, especially for kitchen use.

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 Chosera 2K removes light surface rust, reestablishes the bevel and edges and leaves a respectable working sharp edge that is ready for use or more refinement. The slightly softer matrix of this stone lends itself to the harder steels.

On Carbide Forming Steel and More Abrasion Resistant Steel Edges such as VG-10, D2, M2, S35V, S90V, etc., The 2K Chosera stone is more of a mid-grit level finish stone. It still removes matrix steel and carbides and forms a shiny but not mirror finish when the edge is prepped properly beforehand. But if not prepped with lower grits, it begins to reveal previous scratches not yet removed by lower grits. The 2K edge on these steels is more refined and still a little toothy. It can be used as is, or to be further refined with stropping or finer grits stones.

Hacks and Tips:

  • Use a moderate amount of water when sharpening with this stone to avoid the black swarf from turning into a thick paste. A cleaner surface will cut faster than a thicker pasted one.
  • If using this stone as a final or polishing grit, keep the black swarf viscous and it will produce a slightly more refined edge.
  • Lap this stone with a coarse or extra coarse diamond plate, silicon carbide (SiC) powder, or low grit wet dry sand paper to keep it consistently flat and clean.
