- Now that we know what to look for, it's time to learn how to straighten those blades! Murray will take you through 20 minutes of instruction that focuses on how to straighten two different types of blades!
As an added bonus, you can see what our crew does when we accidentally cut off our bosses head with both cameras....
Thanks for watching everyone! Remember to subscribe and to always...
Stay Sharp!
I've watched your videos for years, same amount of time my knives have been razor sharp. Thank you for dropping new vids
Yuy
Thanks for the tutorial Murray. I learned a lot. Love this channel.
Man, had this Nakiri done for a customer and then I saw the curves and bends in it.... was about to give up on it. Needed this video! Thanks Carter :)
German Blades- "They are tempered more like a spring than a blade" Love it, that little tid bit was not lost on me.
Many people do not realize that a framing square can be adjusted in a similar manner.
To really have a good reference for straight and true years ago I bought a pair of Starrett parallels and an Incra precision square and straightedge.
The Tagane. That is the champion!
Very cool and informative video. Enjoy listening to your knowledge and passion for your craft Murray!
Not having a Japanese hammer for years I have used a chipping hammer that I ground and polished. Not as good as the real thing but it works very well and anyone that has a welder has a chipping hammer or more than one. The carbide tip of the Japanese one being optimal.
This was a great video. Some expert work!
I know this is an older video. But thank you for the information it was super helpful.
This both convinced me of the importance of straightening blades and also convinced me that, no, I will not be straightening my own blades.
Great video!
I wish I had known that homogenous SS straightening story last week! I had that same "it just springs back" problem with a bending stick and a Henckels...
Why the brass hammer in the wooden stump? Does it put less stress on the blade then the anvil in steel hammer? I am asking because I just recently had a couple of laminated knives I have been working on and the layers split after quenching
Yup you answered your own question haha
we have another stump behind me (Doughlas) that I also use
Can you buy those tagane hammers? I have a cheap chinese cleaver that has a lot of bend and warp to it and I want to try and fix it. And if you cant buy them are there any regular tools that you can find at a hardware store that could be used in place of them?
Go buy a scythe peening hammer for starters.
Great job on content and a fantastic demonstration of this skill. 👏👏👏
If you pay hundreds of dollars for a granite block it damn well better be flat!! That's the whole point of it!

I have a question. With this technique you can straighten the stock steel before shaping the knife, or does it only work after the heat treatment?
Works both ways but if you're grinding already heat treated knife stock, it could bend and then you'd have to straighten it again. Better to do the straightening as a last operation (if needed).
How would you straighten a really thick blade, like a deba for Instance? I have a two layer laminate deba that has bent over time and needs to be restraightened.
I also Notice Some Japanese single bevel blades always have their tip up, I believe its a result of grinding the ura and tapering the tip. But this always bends the Tip Up and the blade is No longer straight. How would you fix that?
We address that very issue in our Kitchen Cuts 3 Slicing Knives. It can be found here! www.cartercutlery.com/knives/videos-and-books/knife-use-techniques-dvd/ --Cait
Tried to straight a thin knife made of pure chinesium because it had a bend close to one inch wide. Now it’s about 1 1/2 shorter and I’m buying a new, quality, knife.
LMAO your comment just made my day, yeah investing in a nice knife is fun but it can get complicated real quick. The harder the steel the better and longer the edge will last and need less sharpening but will be more brittle and likely to snap under stress as well as being hard to sharpen to a really nice edge.. it depends on what the knife is meant for, im sure you already know all this
How much does it ding the steel on a homogeneous blade? Would it need to be refinished after?
The tagane definitely leaves a mark in the blade which can be camouflaged by grinding the blade in the same direction but usually remains in the blade when all is said and done. It is either that, or leaving the blade bent. --Murray
What size brass hammer head to you prefer. That one looks to be a 32oz?
What neck knife do you currently use most often and why? That one looks jumbo!
Murray is currently using a large Tactical model neck knife, for RND purposes, but his preferred model is the Perfect model neck knife! --Cait
I don't have a tree stump. Can I use my kitchen counter?
Where can I get a bending stick? I live in the UK
When you pay a certain amount for a knife it sure is pretty disappointing when it is not straight to begin with and you begin to wonder if you should pay a little more next time and buy from another vendor. But you get what you pay for I guess.
Have laid knives straight on table and bent to flatten, similar to grooved paddle technique though with some success (probably not the safest).
are these tips more for pre or post hardened blades?
For both! --Cait
Lol I brought a pretty wonky hand forged Chinese style chef's knife to Murray, I feel like this video was made in response to how weird that knife was!
it's hard to see the flaws from the camera's angle.
Thank you for the feedback! Catching some of the flaws can be very difficult because they're so small, but we can definitely try a few better angles! --Cait
I found that, at least in my experience, it got easier to catch some of the issues on the camera after I had more experience catching them in person. It's a little bit of a bummer, since the point of watching the videos is to pick up tips on how to catch them, but if you pull the video back up if you have to straighten a knife or at least are holding one you know is Bent as a comparison, that helps me. I have a couple of weird medical eye issues, so my eyes don't work together and my vision's not correctable to 20/20. Even for me, though, after enough experience with different knives, I can pretty quickly and consistently pick up the twists on the camera, although it's significantly harder than it would be in person. I'm not a blade smith or anything close to it, but I love knives and try to take the time to sharpen kitchen knives for neighbors or anything like that when I can which does a service for them without a lot of effort on my part, and gives me experience with a broader a variety and quality of knives. I prefer to carry and use quality knives myself, but old junk kitchen knives thrown in a drawer are great for practicing spotting bent blades...
If I want to obtain one of those special hammers with a carbide bit welded into the hammer head, isn it possible to buy them in this country or do you have to make them yourself ?
Very helpful post,
Will Mack
It looks like Murray's made some of these and is selling the tagane hammers on his facebook right now...
I couldn't keep a *straight* face with Doug.
🤣🤣🤣🤣
