Which blade lasts longer on synthetic upholstery?
Stainless steel typically offers better corrosion resistance and wear life on synthetics; add coated edges when available for reduced friction.
How do I reduce fabric fray on fine knits?
Use a micro-honed edge (e.g., Teijin Seiki) and replace blades proactively. Maintain consistent tension and clean guides to minimize snagging.
Can I mix blade families across different holders?
Generally no—match the blade family (Gru Gru, Hercules, Teijin Seiki, Celanese) to the intended OEM holder and clamp geometry.
Carbon vs. stainless—what should I pick?
Carbon steel for maximum initial sharpness on dense stacks; stainless steel for humid plants, longer runs, and easier handling.
