How to identify an old knife

So, you picked up an awesome knife for $3 at a yard sale or your grandfather gave you his favorite blade and now you’re curious about what type of knife it is and what it’s worth. If you’re looking for an easy way to identify what type of knife you have, here are good places to start.

Find any identifying marks or symbols

The first, and most obvious, place to start is with the knife itself. Look for any sort of symbols, initials or identifying marks. Certain symbols or scratches in the handle or steel of the blade are usually calling cards of certain knifemakers or brands. Sometimes a simple Google search on whatever is on the knife is enough to identify the brand or maker.

Narrow down any possibilities by analyzing the construction

If there aren’t any intentional identifiers on the blade, it’s still possible to narrow down the possibilities of where, when and who it came from by simply looking at the qualities of the knife. For example, if you have a knife with a specific type of lock, you can usually narrow the date it was manufactured with a little research. You could also narrow down where it was made by looking at its style and influence.

Post your picture on websites

The Internet gives you access to billions of people, including many helpful knife enthusiasts. There are many websites, such as Blade Forums, where you can submit pictures of your knives and they’ll do their best to identify your knife.

Get a knife reference book

How could a book be possibly better than the Internet? On many levels, posting your picture is much quicker and easier when you’re trying to ID a knife, but it’s not always as educational. While searching through a reference book like this one on Randall knives for clues, you’ll learn about various styles and will be more likely to spot those rare knives that are being sold for cheap at the garage sales. Picking up books like the annual “Knives” publication will fill you with the knowledge that separates the dabblers from the diehards.

Go to a knife expert

Finally, if you’re all out of ideas and no one can help you, it’s worth seeking out a knife expert or museum curator. You never know if your knife is so rare and valuable that not many people know about it.

      Inox is used to mark stainless steel knives outside the USA as well as Rostfrei and plenty of others. Maybe that’s the Inoxi part though. Cortty I Imagine is the maker or place it was made.

  11. I’m trying to identify if my knife I have is a vintage Randall BC Sheffield English British commando fighting knife. The only markings I can find are on the blade side of the hilt. One side is stamped England and the other is stamped with and I and an arrow. If anyone could help identify it I would appreciate it

  19. Has anyone heard of SAVAGE branded Folding Knives?

  20. Could use some help tryin identifying knife. It’s a big single blade knife it looks like a case or an old-timer but it has no markings no nothing I’ve asked people they said case old-timer Old Hickory but I was just wanting to know for sure if you could help me I would appreciate it very much thank you.

  21. I have a knife my friend gave to me, it’s a big recurve/ bowie style knife with a long hooked backbone and above the tip of the blade is a few notched points . The knife brand logo is a wine bottle pouring into a chalice. And the handle is wood but it’s different colors.

  22. I have a 14.25″ long kitchen carving knife (9″ blade). Carbon steel, mid 1900’s or earlier. Marking on blade has the word “Stiletto” engraved within the outline of an arrow with points on each side. Has anyone seen this emblem? In looking up “Stiletto” I only find the illegal/switchblade types of knives.

  23. I have a knife a friend gave me it has no emblems or markings visible . It is one of the oddest knives I’ve seen it looks kinda old I would say from the 70’s or 80’s I think. It’s a lock blade Bowie knife ! Lol! It has brass and wood handle and the locking mechanism is on the side this weird brass flip lock thing ?….. Its 17″ long opened the handle is 6.5″ and the blade is 10.5″ . I would love to know the fact on it . If nothing else it’s a great peice for my collection . Does anyone have a clue ?
