No, the clown isn't the one that states 'steel is steel'....
right back at ya.
Steel is most definitely not steel. Even if the same steel is used in two blades, the forging and folding process itself can yield wildly differing levels of quality.
Someone should probably point that out to your 'expert'.
PS: The long bladed curved Katana is called a Daito. I mixed up my terminology. My bad. A choku-To and a Daito are both Katanas however. The only difference is that one has a curved blade, and one has a straight blade. A 'Ninja-To' is a sword of which no historical examples exist(leading one to believe they never existed at all), but there are existing examples of Choku-To Katanas.
