Spalling raw chunk of chert

[keanoman1000]

can you get a spark off that stuff like you can off flint ?

[brutallindigo]

NIce I wish I had chert like that around here .I've got quarts LOL

[cepson]

Is it just me, or does this video halt and jump around a lot? The audio is fine, but most of the action is chopped up.

[Flintknappingtips]

@cepson It's not you. The video didn't upload right unfortunately.

[bullriderfxxx]

[madipl]

[scrumptiousvittles]

"blast" is totally the right word...

[Flintknappingtips]

Ha!

Do ya ever get cut? I know I do! Marty, your the best man! Keep up the good work showing folks tips and such!

[hopperquartz]

Someone commented on another vid that you are from Arkansas. true or false?

Wondering if you have ever done work with Novaculite? There are lots of the most colorful novaculite in river bottoms around where I live on the Caddo river.

[Flintknappingtips]

True, these videos were made in St. Louis but I live in Arkansas. I prefer raw, glassy chert to novaculite, but I have worked it. If you have access to it you should experiment with heat treating and working it.

[hopperquartz]

And to think I bought videos to learn new tricks when all this stuff is on youtube for free lol. Good work!

[Flintknappingtips]

Thank you hopperquartz

Where do you get your rocks?  I need rocks. Bad.

[Flintknappingtips]

Midwestern chert like this chunk of burlington erode out of the burlington limestone formation. A good way to identify knapable material is to look in creeks and rivers to see what is eroding from upstream and follow to the source. Construction sites near these sources often produce a lot of material also. Find out if there is knapable material where you live. Post a question on paleoplanet message board to find out.

What is the purpose??? Is he Recreating stone tools or is he doing rock art???????????Or is this a geology thing????????

[Flintknappingtips]

recreating stone toools. The parent material (chunk) is reduced into pieces in this case to produce flat bifaces (worked on both faces) The bifaces can be used for projectiles (arrows, darts, spear head...) or knives.

[scalpcreek]

Great video on replication, like using the flint nodule with cortex as a hammerstone....slow hammer, big mass hammer, big spalls. Very cool marty!

[Flintknappingtips]

Thanks Jerr

So would you suggest against using a large (12x10x4cm) basalt hammer for spalling? I sometimes get decent spalls, but they often have large bulbs and undulations. Will a softer hammer help?

[Flintknappingtips]

Basalt hammer is pretty hard I think. I would suggest trying a softer hammer. A good medium hard sandstone hammer works great for spauling if you can find one.

@Flintknappingtips have u ever just knapped with just hammer stones?..no copper and no antler..ive tryed it and it works well if u can find thin pionted hammer stones.made some nice arrowheads with just hammer stones

[Flintknappingtips]

@5tonyvvvv I knap with just hammerstones a bunch. Love it. I quit all my other tools for a year and just used hammerstones except notching. was a great learning experience.

[5tonyvvvv]

@Flintknappingtips how about antler?..i just use stone and some time antler

[Flintknappingtips]

@5tonyvvvv my videos pretty much show all my tools besides wood, which I also use. I use antler billets and punches regularly.
