Social distancing due to Covid-19 has meant I have to start new hobbies around the house. She became such do-it-yourselfers. I have no experience with such a tool and it was great! I had to rearrange the door catch as the door sags and no longer closes or catches the latch properly. The smallest was perfect. I used a hammer to poke out a larger hole and was then able to more accurately cut out a larger area for the metal piece. They are quite sharp and come with little lids to keep people safe during storage. And they come in a handy bag so they're easy to store together. I am very happy with my purchase.
