Back by Popular Demand: Bora 7 Purple Ceramic Belts

You asked, and we listened. Bora 7 is one of the most requested belts in the shop, and enough of you have emailed, messaged and asked at the counter that we've brought it back in.

Bora 7 is a purple ceramic belt made by Deerfos (Deer Abrasives). It has a loyal following among knife makers and sharpeners, especially those running high-speed grinders on stainless and high-alloy steels.

What Bora 7 Fans Like About It:

• Self-Sharpening Ceramic Grain: The grain fractures under pressure, exposing fresh cutting points instead of dulling evenly.

• Built for Hard Steels: A popular choice for stainless, high-alloy and tool steels.

• Long Belt Life: Users report consistent cutting over the life of the belt when run with firm pressure.

Good to Know Before You Buy:

• Likes speed and pressure: Bora 7 performs best on high-speed grinders. Like most ceramic belts, it needs real pressure to fracture the grain and keep cutting. With a very light touch or on slow machines, it can feel like it isn't biting.
