MagnaCut: An American-made supersteel

The Kline represents our first use of MagnaCut, a new EDC-specific powdered metallurgy steel designed to be ultra corrosion resistant and extremely durable. MagnaCut is the product of Larrin Thomas, a self-professed knife nerd and the guy who actually wrote the book on blade steel engineering. He's dedicated his career to the study of blade steels and their properties. Your blade is the heart of your knife, and the properties of blade steels vary widely. Larrin's mission was to create a new EDC steel that would tackle a classic issue: how do you get the corrosion resistance of a stainless steel with the toughness and durability of high carbon steels? MagnaCut was his answer, and we are proud to bring it to the TJB line for the first time with the Kline.

The Best of Both Worlds.

"MagnaCut has the corrosion resistance of stainless steels, but with the performance characteristics of a traditional high-carbon steel."

- Larrin Thomas, MagnaCut creator and author of "Knife Engineering"

DESIGNED TO GET THE JOB DONE

Made in the USA.

We know that for a lot of people buying products made in the USA is important. It's important to us too, and we're making commitments to make more products here in the States. The Kline is our second USA-made knife, and there are more coming in the future. We are proud to produce the Kline domestically, and we'll continue to expand the products that we make close to home. Stay tuned for more USA-made products in 2023.

The TJB Workhorse.

We've listened to a lot of requests for a larger, more full-bodied knife that was designed to do tough jobs that might be outside the scope of a lighter-weight EDC folder. That's where the Kline came from. It's the knife you've been asking us to make: USA-made, MagnaCut blade steel, Micarta scales, an ambidextrous design and a larger form factor. This is a knife that we are really proud of and we know you're going to appreciate it as well. The Kline will be there for you when you need it most.

Great knife

This is a fantastic knife. I've been collecting knives for over 30 years. We're in a short of folding knife renaissance. Even still, this is a shining example of everything good in a folding knife. Great materials, steel second to none, solid construction, and great fit and finish. A lot of knives with "super steels" lack proper heat treatment. If you have a super steel at hrc 58-60 you're missing the benefits of the steel. This blade is definitely treated correctly. Looking forward to many years of carry.

My intro to TJB and their Kline knife.

My EDC is also my prized knife for show and use. I don't keep a "special" piece for show or to have for an occasion locked up someplace. So I really am into carrying the best you have for all purposes. With that said, the Kline hits all the boxes for me. The Look is unique and clean. The Blade is unique and sharp. The Handles are unique feel right to me. It looks like it will perform all tasks I ask of it and has so far. The customer service from TJB has exceeded my expectations and I enjoyed my communications with Ryan.

First class product from a first class company.

My new EDC go to, very pleased…

This blade is slim, well designed, and the workmanship is impeccable. Razor sharp out of the box. Still adjusting to the ergonomics a bit, my usual EDC is a Spiderco or Benchmade. Although the price is premium I feel the quality and value merits the cost.

Top Notch!

This is probably the most expensive knife I’ve ever purchased and I’m very pleased! I think I might now be hooked on this expensive gear. This knife is amazing. Light weight yet so durable, sharper than a razor, just incredible! TJB definitely has a new fan.
