Manual Blades can be adjusted by hand rather than automatically, like the AutoBlade. This provides you with the ability to fine-tune your blade to a specific length according to your material type.
Aside from the adjustment action, Manual Blades are the same as other standard blades (such as the Ratchet Blade, AutoBlade, and older blades for older models no longer offered -- such as the Fabric Blade, Deep Cut Blade, and Premium Blade). Manual Blades offers the same blade angle, blade material, and available blade lengths as these other older models.
Manual Blades are offered in 1 mm and 2 mm length options.
