Silicon Carbide Sharpening Belts (Super Steel Bevel Refinement)

The Ultimate Bevel Refinement Abrasive for Super Steels

When you are finishing the edge on wear-resistant super steels like CPM Rex 121, CPM S110V, CPM M4, or Maxamet.... standard aluminum oxide belts often struggle. Extreme carbide volume makes these steels notoriously hard to cut cleanly.

We brought these Silicon Carbide Belts into the shop for one specific task: the final few passes on super steel blades. 

Silicon Carbide (SiC) is extremely hard and sharp particles. This allows the abrasive to bite directly into hard carbides rather than riding over them, leaving a crisp, flat bevel and a razor-sharp apex if your into this kind of thing.

Why Silicon Carbide Belts belong on your Bench:

• Extreme Hardness: Harder than standard aluminum oxide, making it the ideal match for high-hardness, carbide-dense super steel alloys.

• Burr Thinning Precision: Designed for high-grit bevel refinement, it cleanly polishes the edge face and slims down stubborn micro-burrs.

• The Perfect Pre-Strop Step: Acts as the bridge between your aggressive ceramic shaping passes (like Cubitron or Magna-Peak) and your final stropping step.

Bench Workflow Recommendation:

• High-Carbide Super Steels: Use after your initial ceramic apexing pass. Run light pressure (not even the weight of the knife if you are capable) to set a clean, uniform bevel, thin out the burr, and prepare the apex for final cleanup on a bench strop.
