Knife Engineering Book Pdf Free Download

[Eustacio Gadit]

Thebook covers the major variables that control knife performance like edge geometry, steel selection, and heat treatment. This is described through different mechanisms that affect knives including: flexing and bending, chipping and fracture, corrosion, edge retention, grindability and polishability, etc. The different grades of knife steels are introduced including their composition, microstructure, toughness, edge retention, hardness, and corrosion resistance. The process of heat treating and processing steel is extensively covered including what happens in each step like austenitizing, quenching, tempering, cryo treatments, and more. That includes an explanation for the changes to microstructure, what the goals are for each step, and how to optimize the different heat treatment steps. And I provided specific heat treatment recommendations for most of the major knife steels. These are all things that knifemakers need to be concerned about for high performance knives. And knife enthusaists can learn what aspects knifemakers are controlling for, what to look for in their knives, and how to adjust their sharpening procedures in terms of edge angle and finish for different uses. I have images of the table of contents below.

The book comes in at a hefty 450 pages. There is plenty of detailed content for the most diehard knife enthusiasts and makers. However, for those of you that are scared of a high page count I would say not to worry. The page count is high in large part because of the hundreds of images that are included in the book. Pure text is dry, uninteresting, and hard to follow. Describing the process of austenite formation without pictures is an exercise in futility. Nearly every idea covered in the book has a corresponding image to illustrate what is being described. This is not that different than how I handle topics on this website. My regular readers will know that I like charts, diagrams, micrographs, etc.

The book is also broken up into digestible chunks. There are four major sections: 1) Steel and Knife Properties, 2) Knife Steels and their Metallurgy, 3) Processing and Heat Treating Steel, and 4) Knife Making. Each section has 5-10 chapters in it for a total of 29, each chapter averages around 2400 words and 12 pages. And each chapter has a summary to make sure you got the major points. Since I went through 8.5 years of Engineering University education I have read through my fair share of dense, difficult books. So when I wrote mine I was striving for comprehension, ease in finding relevant information, and clear structure.

I broke some traditional rules in writing one of these books in that I used the first-person in many places within it, especially when expressing my opinion. And while I cited where data came from when using charts from different sources, individual claims are not cited, instead having a references section for each chapter at the end of the book, so that citation numbers [2, 4, 7] do not break up the reading. These types of choices were for improving readability and providing the book a more engaging style.

Writing for this website has been invaluable. I thought I knew the knife community well after growing up with a father with a Damascus steel business. However, I have learned a lot about what subjects are interesting to knife makers and buyers, what topics are confusing people, and which areas require(d) more research. I have gotten help from several knife makers and companies who volunteered time and materials for experiments to answer some big questions. Many of those experiments have been presented on this website, and that information was very helpful for the content of the book.

One of my big concerns with publishing a book like this is that books in the Academic Press are over $100, sometimes well over that number. I am very happy that I found an option to keep the book cost much lower, at $39.95 (note: the actual price varies based on the whims of Amazon robots).

The book is available exclusively on Amazon both in the USA and several international Amazon sites. It should be possible to buy in other countries by importing from the most convenient Amazon location. Let me know if you have any issues with ordering in your region and I will do my best to get you a copy.

As always Larrin, exhalant job on the finished project although I enjoyed the preview. This is going to be a groundbreaker for sure, great, great inside knowledge that is needed if you want to be a serious knife maker!

I think I will address the elephant in the room which is, why is this not available via ebook? What is the reasoning and rationale behind that? Simply put, I am in a part of Southern Africa where Amazon deliveries are just not an option. We barely get internet here, and I assure you there are no Amazon delivery services or book stores that carry this. Why not just release a kindle or ebook version of this that I can purchase through Amazon?

I concur, I want this book but refuse to use Amazon. I called our local independent bookstore and they informed me Amazon was the only retailer. I just want to support small businesses and people like you without feeding Amazon.

Will there be a digital edition for the second edition? I have been following your website for many years and have learned a lot from it. I look forward to your new works, preferably in digital format, so I can purchase and download them directly online.

Vero Engineering is the product of a passion project by Joseph Vero, who is a mechanical engineer designing drones by day and knife designer by weekend and night. Joseph hit the ground running mid-2019 with his first knife release, the Impulse, which hit the everyday carry knife scene like a meteor. It quickly become one of the more sought-after knives in its price range (literally, these things sell within in minutes in secondhand forums such as /r/knife_swap and Instagram). I was happy to learn that Joseph planned to follow up his initial release with the Synapse which shares much of the same design language but in a smaller and easier to daily-carry package.

Vero Engineering has the Synapse retailed at a base price of $295 which includes one knife with one set of G10 overlays (your choice) and a stonewashed blade. For some extra cash, you can choose to upgrade to a belt satin or hand-rubbed blade finish, Timascus clip and backspacer, and order extra G10 or brown micarta overlays. The prototype Synapse I had to review featured a belt satin blade with red G10 scales.

The owner of the website KnifeSteelNerds has a PhD in metallurgy and he uses the site to create and publish articles and data on all aspects of metallurgy, especially the metallurgy of knife steel (as per the name of the site ). There are around 100 articles to read and they are all really comprehensive but very detailed. They will really bring out your inner-nerd.

Anyways, Dr. Larrin Thomas (the owner of the site) just published a book all to do with the engineering of blades. Personally, I am going to order my copy tonight, but I have heard some great things about it. Have any of y'all read it? If so, what do you think? Perhaps a mini-review is in order?

I am new to the community so this may be something Everyone knows, but when I was learning in Japan the technique of strengthening the blade and creating the metal color variation. The use of extremely watered down fire mortar down the spine or mune, and than kinda drawing x shapes through it towards the blade side to create the tempered line once put back in the forge. Strengthens the blade and helps maintain its edge.

Combined with setting up you cooling baths with a compass, to be lined up with magnetic north and south, Since the molecules are moving at an extremely fast speed when hot, the magnetic poles have a greater impact on them, so when they rapid cool they do so with a stronger result. Sorry, if this is nothing useful just wanted to increase site activity.

That is some interesting information, the process of using clay on the spine of a blade to create a hamon is a technique I have always wanted to try, it also gives me an excuse to make a chopper. As I understand the process the clay keeps the spine from fully hardening as it prevents direct contanct with the quencing medium. Then a blade is produced with a hard edge and flexible spine, cool stuff indeed.

I have heard of pointing the horn of your anvil due north while forge welding to prevent a magnetic imbalance in the piece to be welded and causing incomplete fusion of the pieces. Of course that was stated in a satirical sense. I've never heard of quenching in a north-south orientation.... They taught you that in Japan?

It sounds like you're describing a differential hardening, like is done when creating a hamon, only with a less defined line. The x pattern I imagine is to have a smooth transition in cooling rate from the edge to the spine. This results in a hard edge, but a softer spine thereby strengthening the blade. I'm not experienced at all with these techniques and I'm sure some of the experts in this area could describe it better, I have just never heard of quenching in a specific cardinal direction.. Seems unlikely that would make any difference, but if it is the practice I imagine there is a certain amount of tradition in it rather than it actually yielding better results.

Please tell us more about your background and experience! How long were you in Japan and who did you study under?Have you done any bloomery smelting---either with the Japanese Tatara or Western European or African bloomery setups? Any work with oroshigane? What is your experience with "modern" alloys in bladesmithing Can you tell us about the role of ashi on Japanese blades and why it's not seen in European bladesmithing?
