UNGERCommercial ErgoTec® Ninja 6" Premium Stainless Steel Scraper Blades – Dual-Sided Replacement Blades for Efficient Glass and Surface Cleaning ENB15

Lower quality stainless steel than what I am used to. Already showing rust on edge after 1 week and I even keep my tools wiped down, especially my blades. A corner of the blade completely broke off after using it regularly with light pressure.

These are for my unger scraper. Stainless is a must because I don't always use both sides right away and it annoys me that I have to discard carbon blades that the other side rusts without even being used.
