[TSPROF] Alpha Set of Resin Diamond Sharpening Stones (7 Stones)

TSPROF Alpha — are unique resin-bonded diamond stones with a very smooth surface processing quality and the highest wear resistance. Thanks to numerous experiments, we have achieved the optimal combination of bonding agent and concentration of abrasive particles. 

TSPROF Alpha Diamond Bars will handle any steel up to 70 HRC with no problem.

Each bar is thoroughly prepared and does not require breaking in or preparation, ensuring minimal thickness variations within ±0.1 mm.

TSPROF Alpha abrasives are glued to an aluminum blank with bevels for secure clamping in the abrasive holder.

The bars are packaged in individual blister packs.

The set includes: 

• TSPROF Alpha SD161 160/125 (100 Mesh grit) - for initial grinding, setting the angle, and cutting edge profiling.
• TSPROF Alpha SD101 100/80 (150 Mesh grit) - for coarse sharpening.
• TSPROF Alpha SD61 60/40 (240 Mesh grit) - for the main sharpening stage.
• TSPROF Alpha SD29 28/20 (600 Mesh grit) - for main sharpening stage.
• TSPROF Alpha SD15 14/10 (1500 Mesh grit) - for pre-finishing.
• TSPROF Alpha SD8 7/5 (3000 Mesh grit) - for finishing.
• TSPROF Alpha SD4 3/2 (9000 Mesh grit) - for finishing and polishing.

 

The TSPROF Alpha Set of Resin Diamond Sharpening Stones (7 Stones) is a premium collection of abrasives engineered for exceptional precision in sharpening knives, tools, and cutting edges across a wide range of steels. This set includes seven stones with progressively finer grits, ranging from coarse options like 100-150 Mesh for initial profiling and grinding, through medium stages around 240-600 Mesh for main sharpening, to ultra-fine levels up to 3000-9000 Mesh for finishing and mirror-like polishing.

 

Each stone measures 6 inches long by 1 inch wide and 0.12 inches thick, mounted on aluminum blanks with beveled edges for secure clamping in guided sharpening systems.

 

They are composed of artificial diamonds embedded in a resin bond, designed to work best with oil lubricants like oleic acid for optimal performance.

 

What makes these sharpening stones world-class and the highest grade available is their unparalleled combination of durability, precision, and efficiency, setting them apart as top-tier in the abrasive market. They feature the highest wear resistance among resin-bonded diamonds, ensuring they maintain their effectiveness over extended use without degrading quickly, even on the toughest materials.

 

Developed through rigorous experimentation, the stones achieve an optimal balance of bonding agent and diamond particle concentration, resulting in incredibly smooth surface processing that delivers razor-sharp, professional-grade edges with minimal effort.

 

They excel at handling steels up to 70 HRC—far beyond what many competitors can manage—without requiring any initial breaking-in, thanks to precise manufacturing that keeps thickness variations to a minimal ±0.1 mm for consistent results every time.

 

This level of engineering provides an aggressive yet controlled metal removal rate, leading to faster sharpening sessions and superior finishes that enthusiasts describe as "amazing" and capable of tackling super-hard steels like M398 efficiently.

 

Users and experts alike praise them as "the best stones on the market" for fixed-angle systems, with nothing else coming close in terms of longevity, smoothness, and overall performance, making them a go-to for professionals seeking the highest-grade diamond abrasives worldwide.
