    I mentioned on another thread that I have access to farm land that sits within a few miles of the Spiro Mounds archaeological site near Sprio, OK. If you Google "Spiro Mounds" and do an image search, you will see some of the amazing ceremonial artifacts they found there when they excavated in the 1930's. Here is one picture of some of the points they found:

    ANYWAY... One of the fields that I have been spending some time in (hunting feral hogs) is laden with chert rocks of all shapes and sizes. I would be glad to pick some up if anyone is interested, but don't have any idea what size/shape of pieces folks would want. Many of the pieces that have not been broken are brown on the outside. I have found some white pieces and a few red pieces. Some of these may be jasper... just always lumped them together generically as "chert" over the years.
    Here are a couple of chunks I picked up this week...

    The piece at the top is larger than a softball. Knife is 6 1/4" long overall for size comparison. I would be glad to round some up if anyone is interested. I just need to know what to look for. I can fill small or medium flat rate USPS boxes for just the cost of shipping them. I'm already out there a couple of times per week and actually enjoy scavenging through the rocks.

    I'll take a small box of whatever. I'm about to start knapping, but I have no idea what I'm looking for so I figure I will just practice and get some trial and error going.

    It will be next week before I am out in that field again (supposed to rain here next 4 days), but will pick some up to fill a small flat rate box. Seems like it is just under $7 to ship. I will PM you once I get some together.

    Thanks. It was a cheap ebay purchase of a blade blank. I couldn't pass it up for under $20, being damascus with filework. I have no idea what the steel combination is other than carbon and nickel. A friend shaped and mounted the scales and made a thick leather sheath for it. It occasionally rides in my pocket instead of a folder.

    Those are nice size pieces! Have you broken any to see how they will knap? Id be interested if they are usable. How would you like to be paid.

    I haven't broken any of the pieces. I don't have the time or patience to undertake another hobby right now. I will try to pick up some pieces this week. I noticed a lot of material last week that was already broken, or had a broken surface on at least one side. Those pieces were up to 1 1/2" thick and some up to 6"-8" long. I'm glad to pick up chunks as I am in the area. I don't plan to do any knapping to see how it works. Once I have some available, I can contact those who have expressed interest or post it on the trade blanket. I would be glad to send a paypal invoice for shipping. I don't want to make money off of the deal, I just wanted to be able to supply some folks with materials they might not have available in their area. In order to cover the fee PayPal will charge me for using their services, the cost per box would be as follows:

    Small Flat Rate Box (8 5/8"x 5 3/8" x 1 5/8") $8.25
    Medium Flat Rate Box (11" x 8 1/2" x 5 1/2") $14.75

    This reflects about $1.25 above the actual cost of shipping.

    I hope to be out tomorrow in the field. Rains yesterday and this AM have made the roads pretty mushy.

    As for what to look for, I'd suggest looking for pieces without deep lines or fractures in them. Basically smooth surfaces should be better raw material.

    +1 on that. Another way to check quality is to gently knock on the cobble with another stone; a flawed or fractured piece will make a brief, dull clunking sound, but an un-cracked piece will have a bell-like ring.
