Review on Irwin Tools Blue Blade Bi-Metal Utility Blade, 20-Pack: Top-Quality Cutting Performance by Don Merritt

Not much to say about these blades other than that they last longer than other blades. I do a lot of construction work and my utility knife has been through hell and I'm used to changing blades often, especially now. . However, they hold up far better than any other blades I've purchased or used at work. I bought them for myself and will buy them again once I've finished them. I have a very small complaint. The blades are covered with a thin layer of oil that makes them difficult to remove from the dispenser. The deeper the dispenser goes, the harder it is to get the blades. Not that big a problem shooting stars.
