There you go, horses for courses Patrik at the barista championships didn’t use a WDT tool and his flow was perfect.
Having said that, I love the tool Tompoland has found on Etsy if only for the clever engineering and way it works so seemlessly for no so much wonga. So, we go from a toothpick to a few needles stuck in a handle to a multi cogged rotating machine. I guess the next iteration will be a push button battery operated one that doesn’t even need rotating with your hand….quick! get me a taxi to the patent office!!!!
