This Volgu replica is 11.63 inches long and 3.2 inches wide, it is .26 inches thick at the thickest point with an average diameter of .25 inches. It has a standard W/T ratio of 12.3/1 and average W/T ratio of 10.2/1. The average W/T is lower due to the shape and size of the Volgu artifact blade itself.(not being as wide throughout the length of the blade).
The Volgu artifact itself(also pictured) is 13.75 inches long, 3.4 inches wide and "slightly over" .25 inches in diameter. If you use .25 inches this gives it a stand W/T ratio of 13.6/1. We have no way to figure an average diameter or average W/T ratio because there is no cast available of the blade. The problem lies in the "slightly over" part, because if the blade is actually .27 inches thick, that slight difference brings the W/T down to 12.6/1, right in line to our current replica. This is an example of why precise measurements are needed when figuring W/T ratios. Here is a good link to learn more about the Volgu and see more pictures. http://www.lithiccastinglab.com/gallery-pages/2008januarysolutreanpage1.htm Here is a link to some other pictures I recently found http://paleobox.forumactif.com/ou-voir-des-originaux-f12/les-feuilles-de-laurier-de-volgu-t241.htm
UPDATE: I have learned there is actually a cast of the Volgu which can be purchased from someone in France, although it is very expensive. My friend Jim Winn has purchased the cast and although it is thin, it isn't a thin as the Sweetwater. Hopefully in the future I will have the opporunity to measure the Volgu cast.
