I am changed by this cutter back to a reasonable Cutter from the hardware store, because the much better in the hand and can replace the blades better (especially since there are the blades for easy Cutter anywhere). Besides, I was not convinced of the quality of the included blades that were totally dull after cutting a few meters 0.2 mm thick aluminum, although (the editor from the hardware store was also sometime stump, the blade but has persevered much longer and the aluminum itself dull still cut reasonably unlike this knife which has the Alu sometime more torn than cut). No recommendation to buy, is a waste of money, prefer to buy a set of cheap Cutter with replacement blades. The only positive highlight the good workmanship of the knife itself is (as I said, the blades are Nix).
