A sword for only $45 = a good-looking wall-hanger.
Real swords are made of differentially heat-treated carbon steel. The 440 steel on your's is most likely 440A. An acceptable stainless steel for knives, if properly heat-treated. But a sword for only $45 means it's not going to be heat-treated. It'll probably arrive dull as a butter-knife.
If you wanted a REAL sword, you got ripped-off.
But if you wanted something that looks good on your wall, you made a good choice! I got to admit, it does look good.
