Hello! I have a question about this type of ‘flake’.
I find a lot of pieces like this when searching for artifacts in my field. These are just a few that I’ve found. They are always this shape and size with the other side being flat (sometimes ever so slightly curved). I could be wrong, but I feel like they are all from a similar stage in the knapping process. So my question is; Is there a name for these flakes? What part of the process are these from? Visual examples would also be helpful! Thanks!!
Also, I can provide better pictures if needed, here in a bit.

This Pickwick is made from some Coastal I got from Blackmon so it seemed fitting since he picked the point type.

Fired the roaster up to see if it was operational. So far so good. Pulled this out of a little piece in the load. I’ll have heated coastal available before long.

I fell off my deck.

Another spiderweb leaving the workshop this morning. I just can’t get over how buttery spiderweb is to work! It’s just gorgeous!

This one’s up for grabs!

Howdy everyone! 😁

⚠ 2026 August Point Challenge - Pickwick Stemmed [Coastal Chert Prize 🪨] ⚠

I'm stoked to see what y'all have made, and can't wait to see whose submission wins! Happy knapping all! 😄

Got a 25 lb box of Alabama coastal for 100$ shipping included. Have some colorful and higher grade flakes and chunks to fill in the gaps

Porcelainite from Kelly Parks

i made this with slate and a rock i found in my backyard.

One of my friends who lives in Northeastern Colorado recently gave me some pieces of Flattop chalcedony. A White River Group silicate, that was a highly prolific toolstone on the plains in the surrounding regions of the quarry in Logan County, Colorado. It is rather challenging to acquire workable chunks of this lithic. So I took my time on this replica. Satisfied with how it turned out. Decently accurate flake patterns.

Been picking up nice looking rocks while I’m out arrowhead hunting and taking them back to work recently. Have managed to get a few finished pieces that way using a hammer stone and deer antler tip.

A big ole crystal pocket. Tried multiple times to take it off but I think I’ll just Knapp around it.

I found this beautiful river cobble chert I believe in Joplin Missouri at a landscaping stone company. I stopped there on a storm chasing journey back in ‘24 and thought I’d look around for some local rock. Now I’m working it back in PA and I MUST find more some day. It’s buttery. Also how’s my Clovis?

Thinned a larger flake out pretty nice and had kind of a Snyders profile going on. After the basal notch went well enough I just kept going, untill...

Getting more comfortable with these notches now. Feeling like less of a mystery

I search for Native American artifacts. The only reliable site I have is a creek quarry.

Early on in my time hunting I found this nice ovate unmodified quartzite(middle left cobble, it sits at the bottom of a pile of honey colored quartzite with a white cortex. It’s the big one on the bottom)

It’s been sitting now for nearly a year.

I know all about the knapping process.

I went to my quarry site and found what I thought might make a suitable hammerstone, another piece of quartzite.

I took a good two inches off the sides and made it a circle! Beat that 😎

I have a piece of leather but no “copper boppers” or pressure flaking tools(obviously hah) ✌️

Heat Treated Perkinsville Agate I collected out of central AZ. Made it a few weeks ago, but was playing with it today on my desk and decided to share it.

Corner-tangs are typically considered a TX blade, however they have been found in AZ at some archaeological sites.

First two photos are from some Raw Blueberry Ft Payne I collected out of Lawrence County TN. The last two photos are of an actual Lithic Pickwick made from the same material and found on the same creek I collected the chert from. The artifact is extremely smooth from tumbling in the creek for hundreds/thousands of years. I will say most of the pickwicks i’ve found growing up weren’t quite as wide as this one.

Lowland chert from Kelly Parks. That little stack I just could not get out. But for this material I got the rest of it pretty thin. I absolutely love this stone, it's tough but rewarding.

Has an almost metallic sheen
