I suspect that one or maybe both of these knives are infi and will post the results as soon as I get a chance to do the gun blue marker test on the leading edge. Probably needless to say, but I confess my piglet / greenie knowledge on these Busse knives. The reason for no pics on the Mean Street knife is that I thought the Badger Attack was a Badger Attack Mean Streets. Why? when I got the knives home and inspected them, I found a hand written piece of paper under the velcro flap of the Eagle sheath on the Badger Attack. The paper reads,,Busse Mean Streets. I have since revisited my source and have purchased the Mean Street. The mean Street is of the same era with the smooth slotted bolts, is a fatty and from my gun blue marker test, confirms to be infi. I will post some pics of the Mean Street when I get a chance to snap some and will also post more info on the pair I orginally posted here. Thanks to all you guys here for helping me to touch the tip of the iceburg here in educating myself on these Great Busse Knives! Regards, Dennis / ikedoc
