All cast resin blocks break. Acrylic is very soft and brittle.
FIF is the absolute worst example for proper technique and procedures. Things break and such on the show due to using the wrong equipment and rushing things. They deliberately place materials that are absolutely doomed to fail. They use pretty material to bait people into using them. The really funny part is there is no credit for a pretty handle. They should stock the pantry with micarta, G-10, and solid blocks of stabilized and natural woods ... but where would be the drama in that.
