Are these ones you are planning to sell?    
Yes, I have a couple facilities that stock my items.
You must have the magic touch or some love of sanding as I don't see any burn marks on that purple heart!
I do get burn marks on occasion but I guess I'm lucky because they usually aren't too bad.
it looks like a mini massacre when I use it. :-) Looks like you figured out how to get away from that.
One thing I did learn about bloodwood is not to pair it "against" a soft porous wood and then sand.  It will bleed and stain, resulting in a true piece of scrap.

Thanks to all for the kind remarks
