I feel like an 11 year old boy when it comes to toys in the mail.
I thought you have done a really nice job on both your blades. I am doing a polish on my Steel Heart as well. The beautifully polished edge of the DC Mutt really contrasts to the double cut finish. I love the use of a sanding pad instead of a mousepad! It even clamps down the sandpaper. I will totally try that.
I often use pieces of 25cent piece sanding belt in a dremel bit to make sanding down lots of material much easier than by hand. I still finish by hand but it goes a lot faster. I use 60 grit for removing material fast or sharpening garden tools
and finer grits for polishing.
I still have to make sure the piece is totally flat by sanding by hand with a flat piece of metal. I have got to 600 grit on one side so far. Here is a link ,sorry about that but Putfile is dyeing.
