my 'handiwork' the hole was drilled at an angle , between 1 and 2 o'clock... it was a complicated crack so this was a way of getting glue right into the centre
What you can't see is that whole front toe area is shattered into three or four pieces across the dowells as well. Of course it could be glued again and bound but that area will be useless. The crack has also run higher up the blade and would need a dowell.
Always go across the grain especially on a fine grit sandpaper, or willow strip like that will happen quite regularly. I cocked up enough refurbs this way early on to have learned my lesson
