Learn the key differences between #10 and #22 scalpel blades for crafting and precision cutting. Find out which blade size suits your project best.
Quick answer
Choose the #10 curved edge blade for intricate, controlled cuts on light materials, and the #22 blade for larger, sweeping cuts on heavier materials like leather or wood.
Size and shape differences
The #10 blade features a curved cutting edge that is smaller and more pointed than the #22. This makes it ideal for detailed work where you need to follow tight curves or make precise incisions. The #22 blade is the largest version of the #10 design, with a longer curved edge and a flat unsharpened back edge. That extra length gives you more cutting surface for longer, straight cuts or for slicing through thicker materials in one pass.
Both blades fit light duty craft knives, but the #22's larger profile can feel more stable when cutting through dense materials. If your project involves delicate paper stencils or thin film, the #10's smaller size gives you better control. For cutting leather, heavy cardboard, or foam board, the #22's extra blade length helps the cut stay smooth and continuous.
Material considerations
The #10 blade is made from carbon steel, which holds a sharp edge well and is suitable for most light-weight crafting materials: paper, card-stock, stencils, film, photographs, tape, plastic, cork, cloth, and lightweight vinyl. The #22 blade is made from stainless steel, which resists corrosion and is also effective on the same light materials, plus heavier items like leather, wood, foam boards, and cardboard.
If you work with materials that might rust carbon steel, such as moist or adhesive-backed media, the #22's stainless steel construction offers an advantage. However, for most dry craft materials, both blades perform well, and the choice comes down to the scale of the cut rather than the material composition.
How to decide: #10 vs #22 scalpel blade
- Choose #10 if: You need precise, intricate cuts on light materials like paper, stencils, film, or thin plastic. The smaller curved edge gives you better control for detailed work.
- Choose #22 if: You are cutting heavier materials such as leather, wood, foam boards, or cardboard, or you need to make long, straight cuts. The larger blade provides more cutting surface and stability.
- Consider material compatibility: If your project involves moisture, adhesives, or corrosive environments, the #22's stainless steel is more resistant. For typical dry crafting, both blades work well. For general dry crafting, the choice is about cut size and control, not material compatibility.
Product facts
- #10 Curved Edge Replacement Blade: The #10 Curved Edge Blade is made from carbon steel and fits light duty craft knives. It has a razor-sharp curved edge for maneuverability and precision. This blade is best for detailed, controlled cuts on light materials like paper, stencils, and film, where you need to follow curves or make small adjustments.
#10 Curved Edge Replacement Blade - #22 Surgical Scalpel Blade: The #22 Surgical Scalpel Blade is made from stainless steel and is the largest version of the #10 design, with a curved cutting edge and a flat unsharpened back edge. The #22 blade is ideal for larger, sweeping cuts on heavier materials such as leather, wood, foam boards, and cardboard, and its stainless steel resists corrosion.
#22 Surgical Scalpel Blade
Which blade fits your project?
Best for
- Detailed stencil cutting and paper crafting with the #10 blade
- Heavy material cutting like leather, wood, or foam board with the #22 blade
Not ideal for
- Very fine detail work on heavy materials (choose #10 for precision, but it may struggle on thick stock)
- Large, straight cuts on lightweight paper (the #22 may be overkill; #10 works fine)
