This is one of those little jobs that makes all the difference to your knife if you can make it look tidy!
you will need a 'slitting disc' that can be clamped in a pillar drill - they are quite brittle so Grace reinforces hers by gluing it to a perspex disc:

put a block underneath to rest your blade on, setting the height of the disc so it is the distance you want the nick to be from the edge of the blade
then gently work the blade backwards and forwards making sure it remains in contact with the block - you can see Grace doing it here:
