Here's some of my better Engravers. The ones in the last two pictures are Scrapers with Engraver Spurs on them that are usually considered a Paleo Tool.
OK so mine are nothing as great as yours, but they are still my treasures. I found them at Douglas Lake, you know when they let the lake dry up. I thought the small piece was a rock at first. Then a friend of mine (Grizzlies Nat. Am. jewlery) looked at it with his glass and said it is bone. The long one is 3 inches and the small one is 1 inch. Thank you.
