Great Quality Blades

These Unger scraper replacement blades were the same exceptional steel that came in the original Unger scraper devices. They were very sharp, and there is no reason to expect they will not hold their edges just as well. They are double-edged, too. They come in a nice plastic case for storing the blades. There were no instructions or anything with the blades (nor with the scraper) so you are left to your own devices to figure out what to do with them. I couldn’t even figure out how to open the case they are in for a long time. There is some kind of sealant around the junction of the two parts of the case that you need to cut through, then you need to pull them apart with great effort, because there are ridged protrusions on the inside and outside of the two pieces of the case parts. Even after a few times of opening and closing them, they still are pretty tight to get on or off.

Pros: Durable, Good Size & Weight, Easy to Use, Sturdy, High Quality
Cons: No Instructions, Difficult to Install, case is hard to open
