@ddljohn-- I'm guessing that you have a pastry cutter made of wires rather than blades. The ones with wires are difficult to use and clean because the wires are very thing and very close together. The type with blades are easier to use and since the blades sit farther apart, it's easy to clean.
I use my pastry cutter all the time-- for breads, pastries, cookies. I mash potatoes and vegetables with it. I've even used it to make the crumbles for apple and peach cobbler. It works great.
