Just wanted to check back in to see if you decided to get the diamond films, or if the stropping on cardboard worked well enough?
I haven’t got the chance to buy all the lapping films and plates but I bought the 1500 grit and I like it!
I haven’t really tested the new stone thoroughly yet but here is a video of me cutting plenty of cardboard with my usual edge finish. And I love the 0.6um cutting edge finish with some light stropping.
I don’t even use my strops any more. 400-600-800-1000 grit, then 60µ-30µ-15µ-6µ-3µ-1µ-0.5µ-0.1µ
And there is no dilemma with shiny vs sharp. It’s shiny and sharp. While it’s not perfect mirror finish, but it does look more than pretty to a naked eye.
