Review on Versatile 8-Piece Kemper Clay Cutters Set - Round Circle Shapes, Multiple Sizes - Perfect for Clay, Bread Dough, Paste, Painting & More! by Michelle Langley

I love these little knives, except for one important detail. When you use the spring part to push out a sound cut (because it sticks) it leaves a trace of the piece that pushed it out. This is how I go from having a perfect detail to the need to smooth out the marker (which is very annoying). The more it sticks, the worse your tone will look. I want the ejector to be the full size of the torch. Thus, no traces are left on the inside of each part. It would be smooth. This probably won't be a problem for people using cling film or some sort of non-stick hack. I have to find one myself.
