The Working Man's Choice: A History of Imperial

The story of the Imperial Knife Company is a classic American success story. It was started back in 1916 by two brothers, Felix and Michael Mirando. They were immigrants from Italy who brought their skills to the "Creative Capital" of Providence. In the beginning, they didn't even make whole knives! They started out making "skeletons", the metal frames of knives, for local jewelry companies. Back then, pocket watches were all the rage, and those jewelry makers would take Imperial's frames and wrap them in gold or silver to hang on watch chains. Talk about VINTAGE JEWELRY for the pocket!

But as the 1920s rolled around and people started wearing wristwatches, those little watch-chain knives weren't as popular. The brothers had to pivot, and boy, did they ever. By 1940, Imperial had grown into the largest high-volume knife manufacturer in the entire United States. Think about that….they were pumping out nearly 100,000 knives every single day!

What on Earth is a "Shell" Knife?

If you have ever picked up a vintage pocket knife at a flea market or one of our auctions and thought, "Wow, this feels really light," you were probably holding a shell knife. This was Imperial's biggest contribution to the knife world during the Great Depression.

Most traditional knives are made with solid metal bolsters (those silver ends) and thick handle scales pinned directly to the frame. But during the Depression, people couldn't afford a fancy bone-handled knife. Imperial invented a way to take a thin sheet of metal, stamp it into the shape of a handle and bolster, and then literally crimp it over a simple inner frame.

It was a brilliant cost-cutting move! It allowed them to sell knives for a fraction of the price of the big names like Case or Remington. These "shell" knives often had beautiful designs embossed right into the metal or had colorful celluloid glued onto the shell. They were the knives that went into the pockets of mechanics, farmers, and soldiers. Speaking of soldiers, during World War II, Imperial made over half of the trench knives used by the U.S. military. They were a HUGE part of the war effort!

The Hammer Brand Name

You might see the name "Hammer Brand" on a lot of these knives and wonder how it fits in. While Imperial used several different stamps over the years, Hammer Brand was their go-to mark for their economy lines. They actually bought the trademark from the old New York Knife Company after it went out of business.

When you see that little arm-and-hammer logo on a blade, you know you are looking at a piece of history. These were the "dime store" knives of the mid-20th century. You could walk into any hardware store or five-and-dime and find a display card full of these shiny treats. They weren't meant to be heirloom pieces, they were meant to be used until the blade was thin and then replaced for fifty cents. But because so many people used them and then tossed them, finding them in GREAT condition today is a real thrill for collectors!

Why We Are Crazy for Imperial Today

You might ask why collectors go nuts for a "cheap" knife. Well, it’s all about the variety! Because Imperial was so good at mass production, they experimented with all sorts of FUN colors and patterns. We often see….cracked ice celluloid, imitation pearl, bright red "candy stripe," faux stag, and geometric "deco" patterns.

They are also a favorite for "cross-over" collectors. Because shell knives were so cheap to produce, they were often used as advertising giveaways. We’ve seen them with logos for everything from soda companies to local tractor dealerships. It’s like a little time capsule of 1950s business history right in the palm of your hand.

What to Look For at Our Auctions

When you are browsing through our upcoming lots, keep an eye out for these Imperial and Hammer Brand treasures. Here is what we suggest looking for….original store display cards, knives with tight blades, "Kamp King" scouts with all their tools intact, unique advertising logos, and those beautiful "cracked ice" handles that look like frozen lightning.

Since these knives were made with thin shells, they can dent easily. If you find one that is pristine, it’s a real find! We always try to get you the best photos possible so you can see every little detail before you place your bid. We love seeing these pieces of Americana go to homes where they’ll be appreciated all over again.
