Greetings
Thank you very much fernando, Atlantia, cornelistromp and theswordcollector.
It seems, that Atlantia and theswordcollector think I's a sharpening steel.
Am I right, and what Atlantia also asked me, that the key feature in sharpening steel is that it is very hard ? The steel have to be very high carbon steel to quench it very hard. The surface of the sharpening tool, grooved or slick, has to be very hard. I think (If I have understood right, that quenching is making steel hard and tempering is making steel for instance more flexible after quenching) sharpening steel is not tempered at all, so it is very hard and it breaks quite easily.
Well, I do not have any means to measure hardness of the blade, Rockwell or any else scale.
So, If it is sharpening steel, the marks in the blade had to be engraved or chiseled before the quenching the blade. There is no any factory markings or any stamped marks in the blade. These engraved marks look quite primitive to me and I don't believe, that these are any factory made. Also there is many scratches in the blade, so I don't think that the surface of the blade is exceptionally hard.
Or if it is a fake, it must be tempered again in that degree that it is soft enough to grind and engrave it. Well, it's maybe easier to do a new dagger altogether and add also the thumb guard which is missing.
Thank you especially cornelistromp from putting reference in your message. It was very thrilling to read your learned opinion.
Atlantia for idea and links concerning sharpening steel. That idea I must think carefully.
I would like to ask theswordcollector, if he is 100% sure that it is sharpening steel, what are the grounds for such strong opinion? It would be very nice to get 100% correct identification.
Fernando, the blades crosscut is actually diamant.
Jussi
