So far so good. In fact, I extended the life of each blade by using a knife sharpener and sharpening a new edge on it. Works very well. Actually happy with the purchase. At least for what I use them for now, which is scraping off old, dried adhesive and plastic tiles that were put on the wall many years ago. They also do a pretty good job of removing old wallpaper behind tile/adhesive. The trick is to set the multi-tool to the correct speed (not too high and not too low) and move slowly. Let the blade do its job and don't press too hard.
