A 4mm blade that tapers to a needle-sharp point, narrow enough for intricate curves yet strong enough for clean trimming through cardstock and illustration board. The lightweight handle balances perfectly for extended sessions cutting paper patterns or trimming mounted work.

Olfa includes practical extras that eliminate trips back to the supply drawer. Thirty replacement blades come with each knife, enough for months of regular use before reordering. A separate needle tip handles pinpoint punctures when you need to start cuts mid-surface or create exact mounting holes. The handle's tapered base transforms into a burnishing tool for crisp folds and transferred designs, keeping your workflow smooth when switching between cutting and finishing tasks.

Blade changes take seconds through a simple chuck mechanism that locks each fresh edge securely. Collage artists, paper engineers, and illustrators working with cut paper appreciate how this knife handles both delicate detail work and straightforward trimming without switching tools.
