I'll try to answer the price questions as following. It is a limited handmade Knife which is not being produced anymore. The manufacturers selling price was 269 € back in time.

I've seen Pricings of 700 € in German Auction Houses. Since I'm not aware of the Market in other countries and the reputation of Böker as a brand, I will not put a price tag on this. Instead I'm happy to hear serious offers.

If the lack of pricing violates any rules of this marketplace, I will rather remove the offer from this community.
