DT , White Raven ; if you do want to make your blade out of metal . Use aluminum or as are friend in The United Kingdom call it al u miniums . Mother tongue my arse . Take a heavy metal rasp to quick form it , tradianlly Anthame are doubleedged . . Remember it does not have to be sharp . I have seen them made from wood to glass , seen blade from 2 inch to 4 feet . It is what you put in it that matters. Mind has a doubleedge blade of 15 inch wire wrappered sterling silvet quillon and pommel and shaveing sharp. Would not sugest you keep it sharp at all , me just old and stupid . A sword is nice but only if you are along and in a big space.
WhiteRaven , do you live alone ? Do you think someone stole your daggers?.
