Perfect for the use I wanted to do with this knife. It cuts perfectly and smoothly no strength high density foam 10cm thick to redo my seats. The blades are very long and quite ergonomic device to hold it with one hand without fatigue. The plus is a free wireless device like the air after a first load 18h, so you can tinker outside or inside without the need for an extension cord. I did not try to cut food because that's not why I was trying to acquire one. For decorators Sunday is ideal for perfectly shaped cut, nothing to do with a cut with scissors or cutter on the foam thicknesses up to 20cm.
