Theirs this two handed chinese sword on amazon with a forged combat steel blade and i was wandering if it means combat steel in the same sense that tempered carbon steel can be used?
Combat steel? No such thing... Combat steel is a commercial product... not a true type of steel, since there is no ASTM grade of combat steel... And carbon steel is a WHOLE list of different types of steel, whether it's tempered or not... The company does not provide what steel specifications it has other than combat steel... So my best guess is that it's an alloy of 1095 or 301 spring tempered... both are resilient to snapping and fatigue, and common in modern swords... however, they do not hold an edge very well and are prone to rusting...
Great answer by JayDub. Amazon isn't exactly a great site for legitimate sword shopping. Look for legitimate retailers specializing in handmade swords.
as has been said before it is a mystery steel that could mean anything honestly I am guessing closer to 1045 than the already mentioned 1095.... or just stainless steel of some variety tldr we all are telling the truth do not buy it
