Replacement snap-off hook blades 18 mm, 10 pcs — Dedra M9039

Replacement snap-off hook blades 18 mm, 10 pcs — Dedra M9039 are a set of ten 18 mm-wide hook-tip utility knife blades designed for controlled cutting of materials such as carpet, linoleum, adhesive tape and cable ties. Each blade is manufactured with multiple break-off segments so a fresh, sharp edge can be restored quickly without tools. The hook-shaped tip allows clean undercutting of materials and reduces the risk of slipping when cutting raised or layered surfaces.

Advantages

These Dedra snap-off hook blades combine a robust cutting edge with the convenience of replaceable segments, providing consistent performance across multiple uses. The hook tip gives improved safety and precision when cutting flexible or fibrous materials, while the standardized 18 mm width makes the blades compatible with many common utility knife handles. The pack of ten ensures a ready supply of replacement blades for workshop, renovation or on-site tasks.

Suitable for

• Cutting carpet and linoleum
• Trimming cable ties, straps and tape
• Workshop and construction tasks requiring controlled cuts
• Maintenance jobs where frequent blade renewal is needed

Key specifications

• Blade type: snap-off with multiple breakable segments
• Blade width: 18 mm
• Tip shape: hook for undercut and pull cutting
• Quantity: 10 blades per pack
• Material: hardened carbon steel (heat-treated cutting edge)

How to use

Insert a single blade into a compatible 18 mm utility knife according to the knife manufacturer’s instructions. Use the hook tip to engage and cut raised or fibrous materials with a controlled pulling motion. When the cutting edge dulls, retract the blade (if applicable), break off the worn segment along the scored line to expose a fresh edge, and continue cutting. Replace the blade when all segments are used or if the blade becomes damaged.

Usage recommendations

Use appropriate hand protection and follow safe cutting practices: keep the blade pointed away from the body, work on a stable surface, and secure materials before cutting. Store spare blades in their original case and dispose of used segments safely to avoid injury.
