Excel Blades 20011 #11 Replacement Hobby Knife Blades, Carbon Steel, 5-Pack

Carbon steel construction gives these #11 replacement blades a fine point and a double-honed straight edge for detailed craft cuts. Each five-pack provides replacement blades for a compatible craft knife, so you can swap out a worn blade instead of replacing the whole tool. The strong tip is designed to flex without breaking and hold its edge and point longer. A light oil coating helps protect the blades from rust.

Where it shines

Use the fine point for precise trimming, scoring, and detail work across paper, cardstock, stencils, film, photographs, tape, plastic, cork, wood, vinyl, cloth, leather, cardboard, and foam board. For example, when shaping a paper template or refining a model-kit part, the angled edge helps guide small cuts that a general-purpose utility blade may not suit as well. These blades are also a practical fit for scrapbooking, stencil work, wood carving, and other craft projects where controlled cutting matters.

The double-honed edge and strong tip are made for intricate work, while the blade’s flexibility is designed to help it resist breaking during use. Rather than replacing an entire craft knife, this pack lets you refresh a compatible handle with a new #11 blade. Excel Blades identifies the blades as compatible with its K1, K3, K17, K18, K26, K30, and K71 handles, as well as standard light- to medium-duty craft knives, including Xacto-style knives.

The listed compatibility is for standard light- to medium-duty craft knives, checking that your handle accepts a #11 blade helps ensure a suitable match.

Best use cases

Choose these blades for detail-oriented projects that call for trimming or scoring a range of lightweight craft materials. They suit artists and designers working with paper, film, photographs, and stencils, as well as hobbyists assembling models or shaping wood and plastic pieces. The #11 point and straight cutting edge serve as a focused alternative to a broader utility blade when the task calls for smaller, more controlled cuts.

The carbon steel blades have a thin oil coating for rust protection. Handle and store replacement blades carefully, and use a compatible craft knife to secure the blade during cutting. Their replaceable format is especially useful in a project kit where a fresh cutting edge is needed for continuing detailed work.

Should you buy it?

This five-pack is a useful choice for crafters who already use a compatible knife and want #11 carbon steel blades for precise trimming, scoring, and detail work. The fine point, double-honed edge, and stated compatibility with selected Excel Blades handles make it a practical replacement set for paper crafts, model kits, stencils, and other hands-on projects.
