Do you have a cutting mat? The kind they sell for sewing crafts has a couple of angle marks. One angle is 45� the other 60�. You can lay the first corner on that angle and mark it, then cut through a couple of layers at a time with a scissors.
If not, you could just draw any angle with a ruler and then make all the cut the same.
I have a punch that does corners for single layers, but I don't think any of them are strong enough to cut through 2 or 3 layers of cardstock.
