allway tool inc. mp gsk3 Master Painter, 4 -InchW, Glass and Tile Scraper Combo Pack

Good glass scraper. The wider scraper is better at preventing scratches on windows than the smaller one. However, the smaller one does have a little bit more power to it when you need to get something stubborn. It is somewhat difficult to replace the blade on the smaller unit. The blades themselves don't seem to last all that long in terms of sharpness though. Seems like I can do one 20x44 inch window with one blade before it becomes too dull to be very effective.Wish there was a good way to re-sharpen these blades as it feels like I'm throwing away a lot of blades that have a lot of life in them. One of the wide blades that came with the kit was not very sharp (one out of 5 blades is not bad). So expect quality control issues.
