I use this three-in-one fiskars corner punch in a lot of my scrapbooking projects. It gives me three different flower corner designs in one tool.
The punch is made of durable plastic and the cutting die is metal. There is a guide that makes it easy to line up the corner just right to get the punch perfectly aligned and then all you do is press down on the top. It gives a nice clean punch every time.
This adds such a special touch to the corners of paper, photos, cards or tags. It looks especially nice when you place a coordinating color paper under the design. I have even used the pieces that are punched out to decorate some of my pages.
The three-in-one punches come in other designs, so look for them wherever scrapbooking supplies are sold.
