New tool idea, with the archeology behind it

Posibly an exclusive weapon in arch update stuff, like, a flint scraper that when used on a cow gives more leather on drop, similar to the ways neolithic flint was used to deflesh and prepare leather in Schipluiden, (Van Gijn, A.L., van Betuw, V., Verbaas, A. and Wentink, K., 2006. Flint, procurement and use. Schipluiden. A Neolithic settlement on the Dutch North Sea coast, c, 3500, pp.129-166.)   《Im an archaeology student so, gotta site my sources》 itd be an early game way to easily make bookshelves making leather easier to get, it could produce less meat but more leather on drop. Found in suspicious sand and stuff in trial ruins, itd make sence as the trial ruins follow a standard body plan similar to that of the "neolithic package" with a rectilinear settlement. Particularly the late neo if we base it off the fertile crescent due to the fact itd be after the PPNA and PPNB, (pre pot neo b) like id guess 6000BCE to allow for the pot sherds,   

Getting leather for leather armour, item frames and books, saddles, takes a while and i think this would make that easier before players can get enchanting sorted, i think it should have the same durability as a stone sword, with the same attack damage as a stone shovel, mabye it could be crafted by surrounding 1 flint with 8 cobblestone in a crafting table, so it could be like it was knapped into a tool,   

I mean, you just added the chalcolithic, and the chalcolithic was the transition between the neolithic and the bronze age, it fits
