「Shaved tapered metal that is narrowed, hacked to pieces, cut down」as COINS that jingle and clink together in one's pocket. Right element of「two battling dogs」「two battling lances」also being the「recipient of many cuts.」Later application to small-valued coins or coins of REDUCED value: after coins were minted out of gold or silver, unscrupulous merchants and other schmucks would use a very sharp blade and「shave the tapered edges」of the coins as a「person in stance of downward thrusting motions making many cuts」and keep the shavings which added up quickly and paid better than honestly working. But these schmucks were careful to not create so much of a difference in the appearance of the coin as to be noticeable, they hoped. By this method the next recipient of that coin was defrauded (as in,「person downward thrusting shaft」) since the amount of metal actually remaining in the coin was less than the face value. For this reason, KNURLING was added to the outer round edge of coins (all those little vertical lines looking like「many cuts」) at the time of minting each coin, so that if a coin was missing its knurling, a recipient would be on notice that the coin had been shaved and devalued, not to accept it as payment (or, weight it first), and more importantly, that the other party in the transaction was a schmuck and that all future dealings with that person should be avoided.
As「person with thrusting penis spurting shaft stance of battling dogs」the glyph refers to COIN payments to a service provider for services rendered. Coins were used as a medium of exchange and to store value for a later use by shamans, making the sale and rental of sex slaves possible as a real「cash cow」「milch cow」business as is said in English (see 牛 as an investment in assets, a means to produce future revenue), with the reference to milking sticky sweet white fluids with little effort not a coincidence. The first money after bartering was cash in the form of coin, not promises to pay coin printed on paper that evolved later. Don't laugh at the fools who trusted gold coins good for nothing except artful decoration at the time just because kings wanted gold and folks said that coins would always have value, or subsequently trusted and accepted paper IOUs issued by banks and then governments as promises to pay gold and silver coins at some later date, because today we have digital binary 0s and 1s in the Cloud as debit and credit balances, entirely ethereal from start to finish, and no promise to remit anything other than more digital entries in exchange, ever…think about that and who is a fool. At least, with a dollar bill or some other paper currency, you can use it to wipe your ass in a pinch.
