Do Glass Cutting Boards Ruin Knives?
Glass boards are terrible for knives — here's why.
YES — AVOID GLASS BOARDS
Glass is one of the hardest common surfaces. It destroys knife edges faster than almost anything else.
Why Glass is Bad
Extremely Hard Surface
Glass is harder than steel — immediate edge damage
Rapid Edge Rounding
Edge dulls 5-10x faster than wood or plastic
Micro-Chipping
Small edge damage accumulates quickly
Makes Noise
The sound tells you damage is happening
Better Alternatives
Use these instead:
✓ Plastic/Composite
Softest option, best for blades
✓ Hardwood
Oak, maple, walnut — gentle
△ Bamboo
Harder than wood, some dulling
✗ Glass, Marble, Stone
Destroy knives — avoid
