Found this in my email a few days ago from Sharp Tools USA. Piqued my interest so I followed the link to Jeff Farris' website. Got a look at the price of this attachment. $254.95. Talk about sticker shock. I'm not predicting a lot of these will be sold.
"The new DBS-22 Drill Bit Sharpening Attachment works with any size twist drill, from 1/8" to 7/8", fractional or metric. Follow the simple, well-documented directions to create a grind that resists walking, cuts cleanly and works better in most materials than a traditional flat grind. You can choose the optimum drill angle and clearance angle, based on what material the drill will be used to cut. The DBS-22 will arrive in the United States in early October. You can be among the first to own this amazing new attachment. We are accepting pre-orders now, but will not bill your credit card until your DBS-22 is ready to ship."
