Making a blade. 
Setting the width
Next the blade should be trimmed up to the dimensions required (in this example 22 mm to 31 mm).
I usually spray primer on the blade, then mark a line from 22 mm (45 mm in) to 31 mm (73 cm in).
Close up of spine

GC4
After that had been trimmed, mark a line about 2 mm from the back and another line in the centre of the spine.  Grind from one line to the other to make 1/2 the mune. Note the clam shell shape of the cutting edge.

Other side

GC5
Next mark out the line 2 mm from the back on the other side and grind to finish the mune.

Marking the kissaki
Next mark out the kissaki and grind off the excess material.
More marking

GC6
Place a line about 1/3 of the way from the back (about 7.5 mm in this example) and mark a line that follows the curve of the kissaki.

Finished half of kissaki

GC7
Grind to the line and down to the dull cutting edge to form 1/2 of the kissaki.
