Block to grind a threading tool

My attempt to model Craig Campbell's tool as seen in the Shadon HKW YouTube Video here: https://youtu.be/_GOu6db4EJc

If you use Fusion 360: http://a360.co/1M241KL

You will need to drill and tap for a couple setscrews to suit your preference (metric/imperial size etc) to hold the tool in the block.
