The OLFA® AK-4 art knife is designed to be held just like a pen to fee natural and comfortable in the hand, and has a cushioned rubber grip for absorbing pressure - reducing hand strain over prolonged use. The knife's weight is distributed throughout its body such that is feels perfectly balanced. Changing the blade is simple - just spin the shaft to release it, fit the new blade and spin again to lock in the new one.

The knife comes as a pack with two Precision Art Blades, a Chisel Art Blade and a Curved Carving Blade.
