        <![CDATA[ This may seem a little odd to most here, but there is actually a practical purpose to this. I have a foot-ball shaped nodule and want to make it square.So with six blows, I'd like to make a brick out of a football-shaped nodule. Hard or Soft hammer? Chisel a 'scratch line' first, like scoring glass? What would a rock splitter do, a nice clean cut? How would you do it? This is all off-margin. Now why. First is I'm cutting gun flints on a 10 inch lapidary saw and square is better to start off... ]]>
