So you want to track down The Clue Of The Broken Blade The Hardy Boys Mysteries
Most people looking for this are either trying to read it again or find a copy for a kid. It is Hardy Boys number twenty-five, first published in 1965. The short version: Frank and Joe get pulled into a case involving a stolen formula connected to fencing equipment, and a broken blade is basically the physical clue that kicks everything off. The plot centers on a fencer named Carl who dies during practice, leaving behind a broken blade. That blade is not just sports equipment. It turns out someone hid something inside the hollow handle, and the mystery unravels from there. International connections, a missing document, and some pretty standard Hardy Boys shenanigans with the bad guys. Nothing groundbreaking, but it holds together reasonably well for a book aimed at kids in the mid-sixties. I remember buying a used paperback copy back in 2003 from a thrift store in Ohio. The binding was already splitting, the dust jacket had been replaced with one from a completely different book in the same series. I actually noticed because the colors were wrong and the title font didn't match the edition I was familiar with. Pretty common problem if you are shopping secondhand. Always check the copyright page before you hand over cash.
Here is the thing most people miss about finding these books. The Simon and Schuster paperback editions from the seventies and eighties are the most common ones floating around, and they are widely available through used book sites. The original Grosset and Dunlap hardcovers are a different beast entirely. They sell for anywhere between fifteen and sixty dollars depending on condition, and a lot of the copies in circulation have heavy shelf wear, dog-eared pages, or writing inside the front cover. If someone is selling a "near mint" original hardcover for twenty bucks, it is almost certainly a later reprint. Check the barcode number and the publisher's key at the bottom of the copyright page to verify the printing date. For the paperback route, you have a few real options. The most straightforward path is checking Amazon's marketplace and eBay listings. Search for the title along with either "paperback" or "hardcover" to narrow things down. The Kindle version is also available through Amazon, which is usually the cheapest way to get your hands on the text if format does not matter to you. I should mention a practical issue with the digital edition. The Kindle version is a straightforward text scan, but the chapter illustrations from the original printing are not included. If you are collecting these for nostalgia or illustration purposes, that is a significant gap. The physical books have small black-and-white drawings by John McManus scattered throughout. They add atmosphere even if they are modest by modern standards. Worth knowing before you commit to digital.
Project Gutenberg does not carry this title because the copyright has not expired in the United States. The Hardy Boys series as a whole was written under the collective pseudonym Franklin W. Dixon, and the copyrights run well into the modern era. So you will not find a free legal download of the full text anywhere. That eliminates one search avenue right away. If you are trying to read this for the first time and want context, the Hardy Boys books were not originally written in strict chronological order. The Clue of the Broken Blade takes place somewhere in the middle of the early run, and while it mostly stands on its own, there are references to Frank and Joe's ages and some prior cases that will make more sense if you have read earlier books like The Hidden staircase or The Cabin on the Chippewa. Not essential, but helpful. One edge case worth noting: a lot of the older printings have slightly different titles or subtitle variations on the cover. The internal text is generally the same, but if you are looking for a specific edition because a teacher or a collector asked for it, make sure you confirm the publisher and year before purchasing. I once accidentally ordered a Scholastic book club edition thinking it was a standard retail printing, and the paper quality and trim size were noticeably different. Nothing wrong with the book itself, but it was not what I needed.

The best places to actually buy a copy in reasonable condition are eBay, AbeBooks, and the Amazon used marketplace. AbeBooks tends to have better coverage of the older Grosset and Dunlap editions, while eBay is more consistent for the later paperbacks. Prices have crept up over the years. A decent paperback copy will run you anywhere from five to twelve dollars, and aVG hardcover is closer to thirty or forty. If you want to read it without buying anything, your best shot is your local library. Most branches carry the paperbacks in their children's or young adult sections. Some libraries even have the original hardcovers in their reference or special collections. Interlibrary loan is an option if your home branch does not have it. I have used that system for obscure Hardy Boys titles before and it usually takes about a week to arrive. The audiobook version exists through Audible and a few other platforms. It is narrated and uses the standard text. Not much to say about it other than it is a serviceable way to go through the story if you prefer listening. Some readers find the dialogue a bit stilted since the prose style from the sixties reads differently out loud than it does on the page.
That is pretty much all there is to it. Find a used copy, check the edition details, and read it. The story is straightforward, the clues are fair for the target age group, and it remains one of the more commonly discussed Hardy Boys entries among fans of the series.
