Some cool stuff, but not much I need with any regularity. Other sources are more than fine. I'll be excited when they stock the types of high-carbon steels that Aldo Bruno[0] sells.
They are offering free shipping on orders over $50... I wonder if they honor Prime also? Might be rather lucrative (for the customer) as steel is deceptively heavy in bulk. Thinking about stuff like the 1" steel rod I used to use as material in shop class for lathe work.
I'm still waiting for someone to disrupt the hard to search supply shops like Jantz: http://www.knifemaking.com/Default.asp
