Deli Utility Knife, 18 mm Snap-Off Blade, Slide Lock, Perfect for School Crafts & Office Use - Blue

The blade is pre-scored with multiple segments. When the edge dulls, you can snap off a used segment to reveal a fresh cutting edge. Continue refreshing as needed to maintain a sharp cut, without needing a full blade replacement.

The slide lock is a positive locking mechanism that holds the blade length steady. To cut, unlock the blade by adjusting the slider; when you’re done, lock it back to prevent unintended movement.

Use the retracting mechanism to push the blade fully back into the handle. Make sure the blade is completely inside before placing the knife in a drawer or transporting it.

This knife uses an 18 mm wide snap-off blade and is compatible with standard 18 mm segmented blades designed for Deli snap-off knives.

It features a textured grip for better control during longer cuts and a bright blue housing that enhances visibility in busy workspaces.

Great for school crafts, arts-and-crafts projects, light packaging tasks, and routine office trimming where a precise, controllable cut is needed.

Keep the knife away from children, use the safety features as intended (slide lock and retractable blade), wear appropriate hand protection if needed, and avoid using on hard or inappropriate materials that could cause kickback or blade damage.

Simply snap off the used edge along the pre-scored segment to reveal a fresh edge. Do not pry the blade; replace by snapping to the next segment until all edges are used, then consider a full blade replacement.

Compared to similar models, the TD502-BL emphasizes a positive slide lock, textured grip, and bright blue housing for visibility. For alternatives on Fepy, you can explore the red variant and a black variant of Deli’s 18 mm snap-off line, which share the same snap-off mechanism and safety features with different color options.

Consider blade edge life (how often you refresh), visibility of the housing (color), grip texture for comfort during longer use, and whether you prefer a specific color for color-coding tasks. If you want a similar mechanism with a different color, the red or black variants offer identical functionality with a distinct look.

Wipe the handle and blade area after use to remove dust and debris, keep the blade retracted when not in use, store in a dry place, and avoid exposing the knife to solvents that could degrade the grip material.
