well it all depends on the blade and the look i want from the knife
some i make real pretty and cut notch in the wood ,fill it with epoxy and insert the blade
others that i want a primiteve look,cut notch,apply hot pitch,insert blade,let cool,wrap with sinew
as far as the joint goes,i mke the notch in the wood slightly bigger than the thickness of the blade
this way there leaves rom for the adhesive and room to adjust the blade so its more or less centered
