Rather for fun than a much-needed tool

You can, if you like me, the opening of the breakfast egg by "heads" accomplished, of course, more easily and accurately reach this action by knife. Thus, viewed from me this object rather than fun-ready running toy at the common breakfast table, because the opening of the ice ranges depending on personal skill and the tension of the mainspring of "barely detectable" to the destruction of Eikopfes. So my rating derived from a regular adventure and fun under the breakfast participants. Nice toy for people with humor and fun at the relaxed stress free breakfast ..
