Your doing fine Leonard........no I wouldn't recommend digging for matates with a dental pick either! My last limestone matate weighed 200lbs, and it still came out with pick marks on it (because it came out upside down).
The late archaic knife looks worthy of restoration (left), and as for the mystery blade (right), of which I have seen before is also a knife, but these double pointed ones have yet to be given a type name, or so I'm told. It's a definite keeper. You didn't slip a caddoan blade in to tease us did you?
Hi Leonard, Yes more is good. Nobody should worry about breakages, I understand that after the first $5,000. Corner tang comes out in four pieces, each worth $1.97 the breakages slow down considerably !
Alot of time one can determine the type of point a metal digging tool found just by the sound. For instance MONTELLS are very thin, say a 4 inch one will give off a high pitched " tinkle ", sort of like a very expensive bone china tea cup disintegrating.
A very large PERD is much chunkier and might have a lower pitched sound more like Walmart crockery.
And something as sturdy as a Mamoth slaying, thick, 7 inch CLOVIS sounds like an ordinary flint core block.
