What you’re up against

Sayagaki
This guy
makes swords.

Actually, he bought charcoal, built a furnace, smelted his own
steel, created his own ingots, then created his own magical pastes. He
sharpened and built a blade and on and on and on to build an
astonishing tatara.

Do you really think an enthusiast is going to buy your ordinary tatara in order to save a few bucks?
