Frequently Asked Questions

Q: What materials can I cut with these SK5 alloy steel utility knife blades?

A: The SK5 high-carbon steel construction makes these blades well-suited for cutting paper, cardboard, thin leather, foam, fabric, vinyl, wallpaper, and general arts and crafts materials. For best results, use with a cutting mat to protect your work surface and extend blade life.

Q: How do I safely replace or snap off a blade segment?
