All About Pocket Knives

I saw a old Solingen knife for sale on Ebay. The seller called it a "Wino" large pocket knife at 8" long with blades open. The large blade is marked with "000." Can anyone identify this knife and explain the triple "0' marking on the blade? I am curious because the seller states the knife is near mint condition. However it clearly has heavy staining/tarnish on both blades, cracks in the handles, and what looks like rust on the cork screw. The seller claims it was kept in storage for an extended period. I assume those old carbon blades can rust and tranish even if they are not in use.

There is no knife pattern known as "wino" and i have not see "000" on any knife tang. Sounds like the seller does not know knives or else is being intentionally misleading.
But to make any helpful comments we need to see the knife. If you provide a link to the auction or the item number, you will get some replies.

Yes I have some questions about the item. Here is a link to the auction: https://tinyurl.com/nye9h7o

The item number is 371948275633.

It is basically a pen knife (1 spring, 2 blades) with a corkscrew on the bottom, a common German pattern. His reference to "Wino" is simply because it has a corkscrew. The "000" stamped twice on the blade flat is of zero significance, not something normally seen and adds nothing to the value. It has no maker's mark, just "Solingen" a city in Germany with a long history of being the location of many cutlery manufacturers and their suppliers. Knives without a manufacturer's marking are of less value than those that are marked. His description is way off. I would call it lightly used and badly stained. Handles as he points out are plastic.
At $0.50 it is an o.k. buy, go much more and i would say look for a different knife from a different seller (this guy gives B.S. for description). It is a commonly seen pattern. Look for one with natural handles (pearl, bone, stag or ivory) and a manufacturer's or merchant name stamped into blade tang, and one that shows little to no signs of use. Expect to pay about $30 for a top example.

Thank you so much for the information!

I agree with KJ, seller is a bs artist, a bad photographer& can't grade knives!
It is now at $1.27, more than it is worth, IMHO.
