Just some points for clarification, other this is really well done and simple sub.
*Is the 1 meter overall length or blade length?? If it's blade length I would strongly suggest shortening it. For what you are wanting to accomplish in purpose and performance you are better off around 30"(76.2cm) with a 25"(63.5cm)blade, roughly, to fit a boarding cutlass style like that sword is in the picture. Though, to be fair, there is enough extant examples around this type that extending blade length to 28"(71.12cm) is not unheard of. However, 39" (as 1 meter translates to roughly) is a lot less typical and is actually not that elegant or quick moving in that type. Just as a note, most handles are no more than 4"-5"(10.16-12.7cm) for a single handed sword.
*The weight is a bit overly heavy, especially for the length. Contrary to modern belief, most swords (of longsword length, so 40"/1.01 meters or so) were 3(1.36kg) lbs and change. 4.4 lbs (around what you put for weight) would be immensely heavy and cumbersome to the point of unusability in this form. I'd honestly suggest about 2.75-3.5 lbs(1.25kg-1.59kg). With it being the alchemized material it is, I'd say 3(1.36KG) lbs would be ideal.
*Just to confirm, the durasteel of the hilt and guard and such is non alchemized, plain durasteel? It reads that way but doesn't explicitly state.
*Force imbuement is usually a master level power, unless you're a specialist in it. And to be honest, on a sith sword it is redundant. The sub would likely be better off having it removed or altered to another property common to alchemy, since really it's not needed. I have a few suggestions that would fit your theme, but i'll leave it to you unless you'd like to hear them.
