- Inside the knife the blade needs enough space so the sharpened edge will not hit the inside of the spring if it is pressed in past its natural resting position.
- You might wish to shape the underside of the tang into a distinctive ‘kick’ BUT leave this until working in steel. Be aware that too much shaping here will lead the blade in the closed position to be sat on two points and just subtle changes to these will radically alter how the blade sits in the handle.
