IMPORTANT USAGE & CARE GUIDE FOR CARBIDE TOOLS
- Full-Square & Full-Blade Strike Alignment: Always ensure the entire striking surface (square face or blade face) makes flat contact with the stone. Striking at an angle (hitting on points or corners only) will cause the delicate carbide tips to chip.
- Break-In Period: Exercise extreme caution when using a brand-new tool. Gradually break in the sharp edges by slowly rounding them off and allowing the tool to adapt to your workflow during initial use.
- Delicate Nature of Carbide: Carbide products are extremely hard yet brittle and sensitive to impact shock. Please handle with care.
- Note on Chipping: Due to the nature of carbide tools, improper striking angles may cause minor chipping along the edges or corners. This is a normal characteristic of high-hardness striking tools and is not considered a product defect. Chipped edges can easily be repaired and re-sharpened using a diamond grinding stone.
- Storage: Wipe away dust, moisture, and debris immediately after use. Store in a dry location.
