It can be challenging (particularly for kids) to open a soft-boiled egg to reach the yolk without leaving bits of shell behind. This cleverly designed German tool (the Eierschalensollbruchstellenverursacher) provides a unique technical solution to the problem. Place it on the egg and drop the weight once or twice and it will drive the rim cleanly through the shell. You can then easily remove the neatly broken circle of shell with a butter knife.
Dishwasher safe, it is made from stainless steel with a silicone handle, requires an egg cup to use, and works best with medium or larger eggs. You know anyone who eats soft-boiled eggs will want one.
