Any ideas as to the origin of this guardless dagger?

You and Spiral both
Well it arrived, blade is tempered steel, not edged but very sharply pointed...so not a letter opener.....however, the balance point is exactly at the point the handle ends/ 'blade' starts. The feel suggested to me that it may be a 'thrower'...seeing as it was very cheap...I took it into the garden and throw it ....not away ....at a wooden board.

Bearing in mind, I am no 'knife-thrower' out of 10 attempts the 'knife' stuck perfectly 9 times.
Certainly not a well made knife...has some age..possibly WW2 era ......but definately functional.
