The Olfa AK-4 professional model pen-shaped scalpel knife is designed for precise cutting of various materials, from thin film and paper to plastic and softwood.

The OLFA AK-4 knife features a metal (bronze) collet for quick blade changes.
The knife's well-balanced fiberglass composite handle allows for precise cutting with minimal effort.
The pen-shaped knife handle is equipped with a rubber insert to prevent slipping.
It comes with three blades: the OL-KB4-S/5 pen-shaped blade (pointed), the OL-KB-F/5 spatula-shaped (chisel) blade, and the OL-KB4-R/5 rounded blade. A blade storage container and a knife cap are also included. A wide selection of blades makes the Olfa knife suitable for a wide range of applications in design, origami, paper cutting, paper modeling, and more.
We recommend using non-cutting mats when working with it, which allow you to:

cut more precisely and comfortably with the knife.
reduce blade replacement costs (blades dull less).
prevent damage to the table or other work surface.
