TSPROF Alpha N (N=Narrow) — 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 TSPROF Boride T2 Narrow Kit (8pcs) on blanks SKU TS-SH1700300 is a specialized collection of abrasives tailored for precision sharpening of S-shaped recurved knives, concave blades, and small-dimension cutting tools, making it ideal for intricate edges that standard-width stones can't easily access.
This set includes eight stones with progressively finer grits: 150, 220, 320, 400, 600, 800, 1000, and 1200 FEPA-F, allowing for a complete progression from aggressive initial grinding and profiling to refined honing and polishing.
Each stone measures 150x12x3mm (approximately 6" x 0.5" x 0.12"), mounted on high-quality aluminum blanks with beveled edges for secure and stable clamping in guided sharpening systems like TSPROF, Edge Pro, or Hapstone.
They are composed of premium aluminum oxide in a medium-hard bond, optimized for use with oil lubricants to enhance cutting efficiency and longevity.
What makes these sharpening stones world-class and the highest grade available is their exceptional engineering for handling high-alloy tool steels and stainless steels up to 62 HRC, delivering rapid material removal with minimal wear, far surpassing many conventional abrasives in durability and performance.
The medium-hard bond ensures rock-solid construction that maintains flatness and consistency over extensive use, providing aggressive yet controlled sharpening that results in razor-sharp, professional-grade edges with ease.
Their narrow design excels at navigating curved and tight profiles without compromising on cutting power, making them indispensable for enthusiasts and professionals tackling challenging blades.
Boride's reputation for precision manufacturing yields stones with superior thickness uniformity and longevity—up to twice that of standard options—ensuring reliable, high-technology results that users rave about as "rock-solid" and unmatched for hard steels.
This combination positions them as the go-to choice for top-tier sharpening in fixed-angle systems, with nothing else offering the same level of efficiency, smoothness, and overall excellence worldwide.
