Boride CS-WX Series 6-Stone Set includes six 6" silicon carbide sharpening stones: F120, F220, F320, F600, F800, and F1200 grit. Compared to the 5-stone set, the 6-stone progression offers smaller grit jumps and smoother scratch pattern transitions throughout the sharpening process.

Boride CS-WX Series stones are premium sharpening stones made of silicon carbide in a hard vitrified binder. Designed for slow breakdown and long service life, CS-WX combines aggressive cutting speed with a more controlled sharpening feel than conventional coarse silicon carbide stones.

Unlike Boride CS-HD, which is optimized primarily for heavy stock removal, CS-WX delivers a cleaner scratch pattern and smoother tactile feedback at the same grit level. This makes CS-WX suitable for reprofiling, bevel correction, and intermediate sharpening of hard stainless steels, tool steels, and other wear-resistant alloys.

CS-WX is the first Boride silicon carbide series specifically well suited for use with light honing oil. Oil improves swarf evacuation, reduces surface loading, and gives the stone a smoother, more controlled feel on guided sharpening systems.

Boride CS-WX stones are mounted on high-quality aluminum blanks in standard Edge Pro form-factor, making them compatible with Hapstone, TSProf K03, Kadet, Pioneer, Work Sharp Precision Adjust with adapter, and many other guided knife sharpening systems.
