The image I sent is off my scanner (sad, considering I own a photography studio) and the imprint visible on the blade is an E inside a circle. No other visible markings on the blade that I can detect. So, your guess is as good as mine. I got it from a dealer at the Las Vegas knife show. I only have this one and a Benchmade Bali, so I am obviously not a collector of B_Fly knives. Any other ideas as to what might give me a clue.... I'll probably offer it on the forum to get into someones hands who appreciate it, but have NO idea as to what to ask for it?!?!
