Lets see your preforms.

[rock]

I know the preforms are out there and people pick them up. Ill show some of mine if you show some of yours. I find them interesting as to the stages they were worked and always wonder why they werent finished. Thanks, rock

Rock I mean this absolutely honestly in all of your photos I don't see a single piece I would consider to necessarily be a preform.
I see a drill or perforator... A hafted scraper and a chopper.. A Morrow mountain with a broken tip And a couple other small scraping or cutting tools.

Preform/blades

Here is a cool one for you rock

I found this unusual flake the other day about 4 inches underground. Other flakes and some points were found close by too, but this one is unique. It looks like it could possibly be an arrowhead preform; it is already stemmed. The only thing it needs is some secondary flaking on the edges and the base ground.

Rock I would have to say that the top four are throw aways and not preforms. why? Look at all the hinges. Materials used in areas where there is a lot of freezing have a tendancy to do that. Materials have to be gathered down 3' or so from the surface. If you are not in an are where there is freezing then something else cause the rock to be cracked. Maybe a bad heat treating process.

Here in Michigan there is very little knapping rock and what there is, is crap to work. The best is found under 3" of water and below the freeze line.


JMHO

(throw aways by the maker not by you as they are still artifacts)

Here are a couple. The second one may be a knife?

Rock, before you think that you may have found a preform, blank, or quarry blank, consider where there may have been a quarry site. This may not happen all the time but I believe most of the time a preform or quarry blank was worked at the site of the stone quarry, and then later refined to a finished product. I think of a preform to be a rough/crude shaped piece of material that resembles the tool or point that is the finished product (refinements can be done at a later time also). You may have a quarry site near where you found those at and that would make them seem like preforms. Aladrid has the more typical shape that a preform should have; it is a great example of a preform (the greenish & white banded material). Johnny X has a few pictured too but it looks like some of them are already finished to me also. I do see a few you have pictured that reminds me of a preform or was an unfinished piece. However, that overall "preform" shape is what people here want to see. I know of my buddies who hunt and would have thrown away that flake I have pictured b/c they find only arrowheads. I always consider that arrowheads were in another tool form before they were even completed. I also see forms, like that flake I found, that would be a great time saving tool to take on the go. I think all it needs is some secondary flaking (micro-flaking) and basal grinding, WOOLAH!

Here's one from Illinois.I found a lot of preforms in Illinois and they all had a lot of work done on them...

 

[curious kat]

...don't know if this would be considered a "preform"....but...it's made of rock (volcanic)...looks worked and I sure don't know what it is, if anything? Kind of look like it might have been going towards being an animal of some sort? Could be nothing to...?

[mainejman]

That's a beautiful piece.Don't know if that's a preform or a finished leaf blade.Is sure nice anyways.

 

[rock]

The ones I posted have no secondary work on the edges. They have been shaped but not finished with the final steps. The round one in this pic the other is broken something.

 

[scepter1]

I really wanted it to be identified as a type of some sort, but it doesn't seem to fit anything here in the Pacific Northwest. Had a couple of suggestions that it must therefore be a "preform"...

 

[GatorBoy]

Try looking at the Spedis leaf blade

 

[painterx7]

Nice thread rock here are some "large biface pieces"

 

[Tnmountains]

Here are a few for you Rock!

 

[rock]

Maybe Im wrong idk but I was under the impression if a tool or knife didnt have any secondary flaking it was then a preform? Is that correct or not?
