What is the difference?
Deeper, darker, and higher contrast engraving resulting in higher resistance to abusive environmental and physical conditions
Higher quality surface finish for a more reflective, aesthetically pleasing appearance

The new Blockplates are laser engraved (Blockplate 1.0 is laser etched).
What's the difference between etching and engraving?
Etching removes a minimal amount of material (less than 0.001 in or 0.0254 mm, about the thickness of a human hair). You’re able to feel the depth with your finger nail.
Engraving penetrates deeper into the metal. You’re able to feel it by running your finger pad over it. It withstands abrasion significantly more because many more surface layers have to be removed in order to get to the end of the engraving depth.
Engraving also improves thermal properties. Increases surface area is a result from a deeper cavity. More surface area has higher heat dissipation given that there is more area that can "escape" or transfer to the environment.
The surface finish is also improved. This means polishing the surface to remove any defects or blemishes and creating a consistent surface appearance. This finish is commonly used in kitchen, hospitals, and factories. This creates a more reflective, aesthetically pleasing appearance.
