Allow me to introduce myself.
I began knife making when my youngest son wanted a Hartsfeld Tanto for Christmas. At that time I could not really afford an $800 Christmas gift, was not at all familiar with the field, and didn't understand why a custom knife could be worth that much money.
I happended into Bob Engnath's Blades'N'Stuff and acquired several of his blades and finished them for my son somewhat in the style of Hartsfeld. I thought they were rather pretty, and being made of ATS-34 and heat treated by Paul Bos they were more knife than I had seen before.
My son was impressed, and I made many more knives based on Bob's ground blades.
