This is my rendition of a knife or dagger used in the filming of several episodes of a well known space-based science fiction TV program. It seems relatively accurate compared to screen shots and photos available online, as far as I can tell, although there is probably room for improvement in some areas. However it would be illogical to wait for perfection.
Offered in 1:1 scale size with a length of almost 11 inches. A small sphere has been included at the end of the blade to blunt it for added safety. You would need to finish the item with your choice of paints and sealants to generate a proper metallic finish, if that is your choice.
Prepare yourself for the prediction of inevitable galactic revolt, assuming you exist in that particular dimension.
An alternate version without the tip sphere may be found at the following
