Boride T2 Series 6-Stone Set 6" x 1"

Boride T2 Series 6-Stone Set includes six 6" x 1" aluminum oxide sharpening stones: F150, F220, F320, F600, F800, and F1200 grit. The progression covers bevel sharpening through fine edge refinement.

Each stone features indigo anodized aluminum backing with permanent grit engraving on both sides for fast identification.

Boride T2 Series stones use specially treated aluminum oxide in a hard vitrified bond. With a Boride hardness rating of 4 and a breakdown rating of 2, T2 combines a hard structure with slow breakdown for controlled sharpening and good shape retention.

T2 is a versatile series for general-purpose knife sharpening. Its range of grits supports bevel work and subsequent edge refinement, while its hard structure helps limit stone wear.

Use T2 stones with water, a suitable water-based sharpening lubricant, or light honing oil to help prevent surface loading and carry away swarf.

The stones are mounted on aluminum blanks in standard Edge Pro form-factor, making them compatible with Hapstone, TSPROF K03, Kadet, Pioneer, Edge Pro, and many other guided knife sharpening systems. Work Sharp Precision Adjust requires a suitable adapter.

Boride T2 stones should be used with oil or soapy water. Do not use the stones dry.

Oil Behavior

Oil Behavior describes how a sharpening stone interacts with oil during use. The property is especially important for vitrified and resin-bonded stones because oil can either remain on the working surface or be absorbed into the stone body. Oil behavior affects sharpening feel, swarf evacuation, loading tendency, maintenance, and long-term stone cleanliness.

Oil-retentive stones keep a stable lubricating film on the surface during sharpening. This improves swarf mobility, reduces surface drying, and creates a smoother, more consistent sharpening feel. Oil-retentive stones are suitable for long-term use with honing oil.

Oil-wicking stones rapidly absorb oil into the internal structure through capillary action. The working surface dries quickly, swarf removal becomes less efficient, and oil contamination may become difficult or impossible to remove completely. Oil-wicking stones are generally better suited for water-based sharpening.
