How to Hand Sharpen a Twist Drill

[wakeup]

Good video Tom. I was shown how to sharpen drills pretty much exactly as you have shown way back in the '60's. Since then I've hardly practised the art. However, inspired by your video, I've just gone out into the shed and sharpened a blunt drill. Muscle memory is an amazing thing, it must be 30 years since I've attempted to sharpen a drill, but my hands knew exactly what to do!!
Thanks
