There´s one, single, exeption.
There is a polish 6H4 present, ("gift"), bayonet, showing saw teeth.
They´re pretty marked.
Scabbard and all metal parts of the bayonet are chromed.
The bayonet is designated as "P 118".
I own the book
Do Karabinkow Systemu Kalasznikowa"
by Zbigniew Gwozd
You can find this bayonet there.
