Now those that know me know I like to try to shim razors even a highly polished or efficient ones because "why not". As previously opined this 0.8 mm polished Diamondback is exceptionally smooth and punches up in regards to efficiency (it's not all in the gap). I figure it is smooth or smoother than a Timeless, 17-4 or RS10 and as efficient as a Wolfman 135 which you may or may not agree with but I suspect I am in the right range. So I used 3 DE shims (cause it can get tricky to use more) which effectively increased the gap by (approximately) 0.3 mm to the Diamondback.
Well the already smooth Diamondback shimmed 1.1 was still as smooth on the first WTG pass and lost only minimal smoothness on my second ATG pass. It was also somewhat louder and more audible on this second pass. There was definitively more (although minimal) blade feel on the second pass. As expected the efficiency of this shimmed Diamondback was enhanced and better than a Wolfman 145 (which can be slightly harsh at higher gaps - try a 0.3 mm increase and you'll see). The shimmed Diamondback was as efficient as any adjustable near its max - think a 3/4 open Tiaga or Sailor or a Gibbs 5 and Futur 5 (from what I recall). Now the only "cheat" I can be faulted on is using the ETHOS soap which makes any shave more comfortable with its hydration but it is now my top tier soap/AS so I'm going to use it and benefit from it.
If you want to shim any razor you might as well do it on a known smooth one like this 2020 polished Diamondback - you won't be disappointed.
