scribe your grooves deeper.

Also get all the oils out of the bone from the Marrow.

Are those marrow oils good for anything?

I have saved a bunch and used it for tanning hides before.

couple of different ways of splitting bone - I prefer a Dremel with a reinforces cutting wheel. Got to get the oil out to make it more brittle. It has got to be dry to get it to crack right - bury it in sand and cook it a bit - cutt off the ends and clean the marrow out - try a few different methods to get what it is you think you want.
