May I ask why you call this a blank? I find these rather frequently, and I still get a thrill out of picking them up. I call these a variety of names. Preform, blade, chopper, big scraper... I've never heard these referred to as a blank. Nice find!!
i got ya! You are like me calling "game stones" "peedabs". Just what I grew up hearing.Thanks, I have always heard preform s called blanks and I use the two words interchangeably. I was very happy to have picked it up.
From the looks I would lean more towards calling it a blade myself. Looks like the edges are worked pretty well all around, and appears rather symmetrical. I always figured blanks and preforms were much more rough around the edges and not quite so thin. No matter what you call it, awesome find thanks for sharing
