Query: I'm hoping to replace it with better

I had an old thrift store pastry blender that I used for years until only half the blades were left. We tend to go through a batch of Master Mix a week in our home, so I needed another functional pastry blender. The only one I could find in the local stores was this Good Cook wire pastry blender. It functions, barely. It does ok on room temperature shortening, but bends all over the place when I try to use it on cold butter. The way the wires bend, I keep thinking they're going to break, but they haven't yet. After a year though, it's reached the point where I have to slice the butter a bit with a knife before taking the mangled wires to it in my mix. Also, the little tabs on the handle have started popping out at random times when I'm mixing. They pop right back in without a problem, but it is a minor annoyance. Basically, the pastry blender is faster than working with just a couple knives, but it's time to replace it with a better model.
