Deep in the bowels of the Badger & Blade archives I came across this site for blades:

I've not tried it, but at least you can order 100 instead of 200. I would be very interested in seeing a review of these blades. Are they, perhaps, Ted Pella blades? Anybody know anything about this site?
Dude, you found Feather's and IP's in bulk too!
