Although this handle holds the blade very well and provides a good grip, it is incredibly difficult to insert and remove the blade from the handle. My goal in purchasing this along with some plastic "razor blades" was to clean my ceramic hob. The plastic blades seemed perfect for this. Unfortunately, getting the blade into the holder is so difficult that I almost decided to return it. In the end I was successful and after installing the blade it works fine. However, I couldn't help but think how awkward it would be for me to exert myself if I was working with a real razor blade. does the job effectively, but I'd be a lot happier if I didn't need pliers to slide the blades in and out.
