My friend, Slovak sharpener Pavol Sandor, uses copper tube for edge testing. In his video you can see it in the time window 46:55 to 48:30. https://www.youtube.com/watch?v=bfp80sYH6iw
He makes static test with inclined blade and forces 1000, 3000 and 5000 gf. He makes also a dynamic test when the blade with additional weight 1000 gf is dropped from a height of 100 mm (4").
