I personally have changed where I was going to index points in a forearm to show the mineral spots and natural defects.  I once had a birdseye forearm that I had planned to put ebony points into.  While turning it down a streak showed up like yours and just kept getting bigger with every turning.  The streak ended up about 4" long and I just left it  like that to show it off.  No points or anything.  I think that kind of stuff reminds people it is still just wood.  Like someone said earlier the defects show it is hand made and gives it character.  I love the look of that stuff.
