ZWILLING KRAMER EUROLINE Carbon Collection 2.0 6-inch Chef's Knife, Stainless Steel

Q: What's the Rockwell? What type and grade metal(s) were used? ANY actually useful information about the blade at all would be nice.

The blade is made of straight carbon steel. Which means the blade will tarnish with use. This will not affect the performance of the knife. Even with the tarnished (patina) blade, it is still a beautiful knife. I own the knife in 6”, 8”, and 10 inch blade lengths. Below is more information on the knife: Forged German Steel - Patented special formula high carbon stainless steel construction SIGMAFORGE® Construction - The knife is forged out of a single piece of no stain steel that for a superior construction and balance FRIODUR® Hardened Blade - Ice-hardened blade provides extremely long lasting sharpness Superior Hardness - High quality 57 Rockwell Hardness ensures an exceptional edge retention Polymer Handle - Ergonomic handle is bonded for seamless accuracy and good balance Laser Honed Blade - Precision honed and controlled blade edge features a 15° edge angle and smooth transition from blade to handle Chef's Knife - Rounded 8-inch blade edge with a heavy, broad construction to allow versatile cutting options

Q: I accidentally washed my son’s knife in the dishwasher. Is it ruined?

No its not ruined, just make sure there is no rusr spots on it, if there is use a piece of steel wool and rub it off and re-apply the oil that comes with the knife. You will be fine.
