Swann-Morton Blades Explained: A Practical Guide for Designers, Crafters and Model Makers
Swann-Morton has been manufacturing precision blades in Sheffield since 1932. The same blades used in operating theatres worldwide are the ones designers, architects, model makers, and artists reach for in their studios. But if you're new to Swann-Morton — or you've always just bought the same blade out of habit — it's worth understanding what each blade is actually designed for.
The three blades you need to know
No.10A — the everyday workhorse. The No.10A has a fine straight tip and is the most versatile blade in the Swann-Morton range for graphic design and studio work. It's ideal for fine detail cutting, straight cuts on lightweight card, paper, film, and acetate. This is the blade most graphic designers and illustrators reach for first. Fits the No.3 handle, No.3L handle, and premium retractable handle.
No.11 — for intricate work and thicker materials. The No.11 has a longer, elongated triangular blade with a strong pointed tip. It offers more control for intricate curved cuts, detailed pattern work, and cutting through thicker materials including medium-weight card and board. If you do a lot of stencil work, model making, or detailed paper cutting, the No.11 is often preferred over the No.10A. Fits handles No.3, No.3L, and premium retractable.
No.10 — for mountboard and foam board. The No.10 has a curved edge and is specifically designed for straight cuts through thicker materials — mountboard up to 1,400 microns and foam board. If you're cutting mounts for framing, or working with foam board for models and presentations, this is the right blade. It's used alongside a Logan mount cutter or a steel rule and cutting mat. Fits handles No.3, No.3L, and premium retractable.
Which handle do you need?
No.3 handle — the standard choice for most studio work. Slim, stainless steel, takes No.10, No.10A, and No.11 blades. This is what most graphic designers, illustrators, and architects use.
Premium retractable handle — increasingly popular for safety reasons. The blade retracts into the stainless steel bayonet when not in use, eliminating the risk of accidental cuts when reaching into a pencil case or toolbox. Takes the same blades as the No.3.
Blade storage and safety
Never leave an exposed blade unattended on a work surface. Use a blade disposal bin or wrap used blades in thick tape before binning — they retain their edge long after use and are a sharps hazard. The premium retractable handle is the safest option for studio environments where multiple people are working at adjacent desks.
Buying in volume
Swann-Morton blades are sold in boxes of 100. If you use blades regularly, buying in volume is the sensible approach — blades should be changed frequently (a dull blade tears rather than cuts cleanly, which affects both quality and safety). At Graphics Direct we stock the No.10A, No.10, and No.11 in boxes of 100, along with handles and the comprehensive Graphic Art Knife Set for those starting out.
