If i buy a copper ingot for 10$ make it into a short blade, smack a grip on there, how does the copper only get marked up to 11$? Usually, if you are doing business you want to make it up at least 100-200% profit above of the original price you bought it at (ex: copper ingot sold at 100% markup as copper short blade for 20$). Is there a way to make this into the game because there is no real way to get up into the tiers of ingots (100,000$?!).
