The outermost lamella has a tendency to bend inwards. It is easy to turn back, I hope the material makes for a longer time with. Moreover, I find the handle a little short for me, glove size 7.5. The handle itself is round but the ends are square. Still a pretty decent tool to fast to cut fat in a short pastry.
Four points from me for now. If a blade break off, I correct the downward.
