According to the purists, authentic katana swords should be handmade in Japan by a master craftsman, with a real hamon temper line to show for it. The sword should furthermore be razor-sharp, exceptionally balanced, and meticulously detailed. As if that wasn’t enough, the sword should be made of steel, but not stainless steel. It should also deliver a brilliant shine, and possess a Mekuki, aka the peg that holds the blade to the handle. Of course, none of this helps you much if you’re buying online from a stranger. That’s why it’s most important to buy from a verifiable source, and leave nothing to chance. Given how expensive authentic katana swords are, you might actually want to travel to Japan when buying one. I’ll see you there!
