Bead blasting is a crucial surface treatment technique that transforms the appearance and performance of knife blades. Whether you’re a knife maker or enthusiast, understanding this versatile finishing method can help you make informed decisions about blade treatments. This comprehensive guide explores everything from the basics to advanced aspects of bead blast finishing.
What Is Bead Blast Finish and Why Is It Popular?
Bead blast is a surface treatment process that uses small glass beads or other abrasive media propelled at high pressure against a blade surface. This technique creates a uniform, non-reflective finish that many knife enthusiasts prefer for its practical and aesthetic benefits.The popularity of custom pocket knives with bead blast finishes has grown significantly because this treatment offers both functionality and visual appeal. The matte look achieved through bead blasting helps reduce glare while providing excellent wear resistance.
How Does the Bead Blasting Process Work?
The bead blasting process involves:
- Cleaning the blade surface thoroughly
- Using compressed air to propel fine beads at high velocity
- Controlling pressure and distance for consistent results
- Creating small pits that form a uniform matte texture
