I had a friend of mine who swore he could flip it fast AND with the blade facing his hand. It did not turn out well. It cut deep into his thumb but he wouldn't go to the doctor.Who has - or at least known someone to nearly need stitches from handeling one with little experience?
I have a cheap 15 dollar one from the mall. I learned a couple tricks with it then lost it. It's only my second butterfly knife lost. I just cant hang onto a blade for more then two months tops.
