Review on Upgrade Your Cutting Game With 100PCS Heavy Duty SK7 Carbon Blades For Box Cutter Utility Knives by Danny Kamerer

two things i love here.amazing price point, u can replace blades more often without feeling guiltynext is the black surface, does not rust.if u are in area where things rust, u know how fast these rustquality is good, blades are sharp, maybe not quite as sharp as the big name blades costing 3-4x more, but unless u are doing precision work, these will suffice. i use them for mostly small box cutting. they work great, will be buying more. great value
