Спросил производителя про клеймо на ножнах. На удивление быстро ответили:

It is not very old, I would say maybe 1980´2 or later. Most likely it has been done for some police forces happening, celebration or gathering etc. It has a stamp Poliisi Polis which is police in Finnish and in Swedish. Both are official languages here in Finland. The sword with lion head is their logo.
