Unior Olfa knives are well-made and have a good grip. Unior knives are equipped with three automatically exchangeable blades made of alloy steel. The blade is replaced by pushing the blade lock all the way.

If the blade loses its sharpness, simply break off the segment at the tip. When the last segment of the blade is used, the blade block is pushed all the way and a new blade is ejected.
