The VS3 comes standard with a 420 stainless steel blade. This replacement blade is titanium coated to grind the coffee beans more powerfully. What's more, the Hypernova Burr is made from 440 stainless steel, which is extremely hard! The Ultra Burr goes even further with a pre-cut design and plasma coat. These replacement blades are especially good for a fine grind and are recommended for those who make espresso at home. Durability and heat resistance Titanium coated blades are more durable and heat resistant. The cutting edge is less likely to heat up during grinding, which affects the durability and sharpness of the cutting edge. Fast and stable grind Titanium-coated blades tend to have slower grind speeds than stainless steel blades (including Ultra). This is because the surface of the blade is smoother after treatment. Although the grind speed is slower, you can expect improved uniformity, especially with finer grinds. *The grind size may vary by 1-3 marks compared to standard stainless steel blades. Before making coffee, please perform a test grind and adjust the grind size. Variations Supernova Gold Titanium Material: 420 Stainless Steel Coating: Titanium Recommended coffee type: Espresso Hardness: HRC60 Color: Gold Supernova Black Titanium Material: 420 Stainless Steel Coating: Titanium Recommended coffee type: Espresso Hardness: HRC60 Color: Black Hypernova Titanium Material: 440 stainless steel Coating: Titanium Recommended coffee type: Espresso (filter coffee) Hardness: HRC65 Color: Iridescent Compared to the two above, it has a medium body, a clearer taste, and a more balanced flavor. It also offers a different flavor to filter coffee. Ultra Hypernova Titanium Material: 440 stainless steel Coating: Titanium, plasma coat Recommended coffee type: Espresso (filter coffee) Hardness: HRC67 Color: Silver *Specification change: The shape has changed from this time, and the grind speed has not improved. Like other replacement blades, the grind speed tends to be slower. (The English text on the box says that the grind speed will be faster, but due to this specification change, the grind speed will actually be slower.) It produces a medium body with lively clarity, crispness and balanced acidity. It is also the only one with a different shape than the other refills, which produces a brighter acidity than previous versions. This is a high-end blade that maintains accuracy through more precise grinding than usual on high-hardness stainless steel, and is titanium-processed and then plasma-coated to achieve overwhelming hardness, durability, heat resistance, and a uniform grind.
