Bought this just over 5 months ago, always had difficulty disconnecting the head to use the crevasse tool. Today when disconnecting the sleeve broke off where it is riveted to the handle, upon looking at this which is covered by an outer sleeve so you don't see it, you can tell with the pop rivet through the plastic this is a very weak point. I glued it today to try and get the house finished not having any luck with finding a replacement part
