The 1x6 Jende 120 grit stone is an aggressive, extra coarse stone used for serious profiling, repairs, and initial sharpening. While not as angry as the Jende 80 grit stone, the depth of the scratches can still leave some longer “whisper” scratches that rise slightly above the bevel. But what it lacks in beauty it makes up for in aggression, and easily replaces the coarsest diamond plates and other extra coarse and coarse sharpening stones.
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:
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 Shapton, Sigma, 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.
The Jende 120 Grit sharpening stone is a mid range 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 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
On More Traditional Carbon Steel and Stainless Steel Edges the Jende 120 Grit 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 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 Grit is probably the lowest grit you would need, and it won’t chip out the edge as much as diamond plates can.
On Carbide Forming Steel and More Abrasion Resistant Steel Edges such as VG-10, D2, M2, S35V, S90V, etc., The Jende 120 Grit 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.
