Spending the week in Zurich at the Ditting factory being a super nerd. Different grinders and customers require different burrs. These are all ceramic burrs. Much harder and resistant to wear compared to steel, but, they're a bitch to engineer and make, are more brittle (rocks!!) and chew through the tool bits that grind their fine teeth. Steel burrs can have their design changed and updated for every set. Ceramic burrs need a $xx,xxx mold designed that can't be changed until it's stamped many many thousands of pieces to offset the cost. Ceramic also shrinks 20% after the oven firing, so the design has to be spot on. Let's stick with steel for now :) Matt Perger(@mattperger)님이 게시한 사진님, 2015 10월 19 오전 4:53 PDT

맷퍼거의 인스타그램에 올라온 사진인데, 사이즈와 디자인은 딱 바리오급 라인의 디자인이네요. 세라믹 버가 내구도에서는 우수한데 몰딩 비용이 꽤나 많이 드나 봅니다.
자세히 보면 윗 두개 날과 아랫날의 직경이 좀 다르네요. 포르테나 바리오는 5x mm 규격이었던것 같은데, 어떤 그라인더를 염두해두고 제작된 건지 궁금해집니다.
