1x6 Sigma Ceramic, Oribest and Select II stones for the Edge Pro, Hapstone Sharpener & TSProf.
The 1x6 Sigma Select II 1K grit stone is a medium stone used for light profiling, routine repairs, initial sharpening, and can be used as a worksharp edge or as a step for continuing to further refinement. One of the most notable features of this stone is the overall balance of smooth aggression.
1" x 6" x 5mm in size and mounted to a steel blank, it is used with water only and work best when soaked in water for a minute or two before use. Store in a dry place in between use.
Abrasive Material: Silicon Carbide
Ideal place in a sharpening progression:
The Sigma Select II 1K sharpening stone is a premium level medium grit sharpening stone that works on almost all types of knives, scissors, tools and chisels, including those made with abrasion resistant steels. While the 1x6 size is meant for use with the 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.
This stone can also be used in a mix and match progression of other synthetic and natural sharpening stones, as well with other brands such as Naniwa, Shapton, Suehiro, Imanishi, Spyderco, King, etc. This is a waterstone, and is not to be used with oil, 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 Sigma Select II 1K works on steels between RC 52 and RC 65 on the Rockwell C Hardness scale. The stone’s formulation and abrasive combo works very well on 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, and 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 Sigma Select II 1K really brings out an initial edge with a natural stone looking finish. This stone really reacts well with the harder RC steels and leaves an edge that is ready to use, and clean and 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 Sigma Select II 1K removes matrix steel and carbides, leaving the surface of the blade prepped for further refinement.
Hacks and Tips:
Comparable Stones: Naniwa Chosera 1K, Shapton 1K, Suehiro 1K Cerax
Alternative Mid Level Stones: Jende 1K SPK, Jende 1K Gray, Jende 1K SF, Naniwa 1K Goken Pro, Nubatama 1K
Alternative Economy Level Stones: Naniwa 1K Chocolate Bar, Suehiro 1K R
