Every Tuesday John Grimsmo does a new YouTube video in a series he calls “Knifemaking Tuesdays”.  Today we got a really interesting video that shows how he anodized a multi-colored Eagle Scout logo onto one of his knives for a customer:

I love engraving, anodizing, and all forms of finishing for CNC projects, so I wanted to pass along this neat video.  If you’ve never done any anodizing before, John has done a lot of it on both aluminum and titanium.  Titanium is neat because you can get different colors as shown on this log by using different voltages.  The other trick he shows is using Dykem as a mask to control exactly what gets anodized.
