I have a knife made in Germany. The telephone number is 1934. I wonder what brand it is. Who can help me see what it says?

The gunner's hollow ground is a way of sharpening, and the term is hollow grinding. The two sides of the blade are concave relative to the back of the knife, which is especially suitable for narrow and sharp knives. That's how old razors open their blades. The original text should be a way of opening the front named by the manufacturer: gunner concave grinding)

Registration form with number 1934 (number is a relatively rare way to write No (number), and regd is the abbreviation of Registerd, with original meaning: registration number 1934).

Made in Germany (Germany)

Sword (probably brand: sword)

From the appearance you described, it should be an old-fashioned razor made in Germany, and the manufacturer's code is 1934. It is not a cultural relic, but it has certain collection value. There are still people who specialize in collecting old razors. I'm afraid only insiders know the specific price, and it should not be too high. Razors should also be unpopular in the circle of knife lovers.
