first and second, opposed, splitting blade assemblies;
the first splitting blade assembly having;
a first splitting blade having first and second, opposite, sides;
at least a first projection positioned at the first side of, and spaced from, the first splitting blade at a location to engage a work piece during a splitting operation; and
,at least a second projection positioned at the second side of, and spaced from, the first splitting blade at a location to engage a work piece during a splitting operation; and
,the second splitting blade assembly having;
a second splitting blade having first and second, opposite, sides;
at least a third projection positioned at the first side of, and spaced from, the second splitting blade at a location to engage a work piece during a splitting operation; and
,at least a fourth projection positioned at the second side of, and spaced from, the second splitting blade at a location to engage a work piece during a splitting operation; and
,the first and second splitting blades being oriented opposed to one another to converge on, and strike, a work piece to split the work piece into two resulting split pieces; and
, the first, second, third and fourth projections being positioned to engage the work piece to contribute to formation of at least one irregular split edge on at least one surface of each one of the two resulting split pieces.
