Watch Knifemaker Forge Knife from Guitar Strings

At this point, pretty much everything has been turned into a knife.

There are the obvious found objects that can be turned into knives, such as old files and railroad spikes. In fact, you can watch these items along with 10 others be turned into 12 different knives in an old post.

Then, Kiwami Japan came along and upped the ante by turning unimaginable items into knives, such as gelatin, stone, and even underwear!

Another of our favorite YouTubers is back with some interesting experiments. This time knifemaker Steve Calvert aka Green Beetle attempted to make a knife from nickel wound guitar strings.

Watch a Guy Wear a Belt of Spinning Knives


The best YouTubers out there are the ones with the best imagination along with the skills to bring their ideas to life. Colin Furze is the best at this when it comes to insane creations (with Joerg Sprave not far behind).

In Colin’s most recent video, the backyard scientist and general madman decided to once again venture into the world of knives with an idea to create a belt of spinning knives to quickly make a salad.

Colin has made some other interesting knife-related projects like homemade Wolverine claws, but his spinning belt of doom is way more dangerous.

Take a look:

He attached eight kitchen knives on hinges to a belt that can spin at 1000RPM all in the pursuit of cutting a salad. You can see he actually gets hurt pretty bad at the end of the video when the belt goes a little haywire (see the growing blood spot on his shirt and the big scratch on his arm).

Hilarious Knife Video Hits Close to Home


If you’re like me, you always look for an opportunity to take out your knife to help when some other tool like scissors could work just as well. That’s why this hilarious video from YouTuber Gus Johnson hit so close to home.

Take a look.

While I’d like to think I’m not this extreme (and I would never ever storm over a couch with an open knife in my hand), my wife and kids would probably say otherwise.

This seems to be the first knife-related post from Johnson and company but the fact that it’s so accurate on so many levels makes me think that Johnson or at least someone from his inner circle is a knife person.

Watch YouTuber Make Knife from Underwear


Do I post far too many videos from YouTuber kiwami japan? Probably. Am I going to stop? Probably not.

Kiwami japan is one of the most ingenious YouTubers out there, making knives from all types of bizarre materials. He doesn’t use regular materials like steel. Instead, he uses everything from Jell-O to aluminum foil.

In one of his most recent videos, he turns underwear into a knife. Yes, underwear.

Watch Miller Knives Turn Rusty Trap Into Knife


Upcycling is the act of reusing unwanted products or waste to make something new and intriguing. Steve Miller of Miller Knives has made a YouTube career out of transforming found objects into interesting knives.

I honestly think one of his most recent videos features his best creation yet.

Miller acquired an old rabbit trap that was not only rusted beyond repair but illegal to use in Australia. So, he decided to turn it into a knife.

Watch Man Make Knife Out of Jello


One of my favorite genres of YouTube videos is watching people make knives out of unusual things. No one is better at this genre than a YouTuber known as kiwami japan.

I mentioned his work in a blog post about two months ago relating to knives made from rolls of aluminum foil, but one of his more recent videos takes the cake.

The Japanese knifemaker makes a functional and razor-sharp knife out of gelatin. That’s right, that soft liquidy substance made from extract from boiled skin, bones, and connective tissues of animals was turned into a knife.

Watch a Knife Get Made From Aluminum Foil

Aluminum is one of the most commonly used metals. In fact, it is one of the most abundant elements on earth. So why is it that people never mention aluminum when making knife blades?

Well, despite being lightweight and durable, aluminum is extremely soft. That means a knife made from aluminum would dull quicker than you could sharpen it. But that hasn’t stopped some enterprising knifemakers from experimenting with aluminum blades.

In March, one of the most creative knifemakers in Japan made a fantastic kitchen knife out of a roll of aluminum foil.

Aside from that Japanese knifemaker, few are more skilled or creative at the videos turning everyday objects into knives than Steve Miller from Miller Knives. I’ve highlighted his videos in the past — such as the time he turned a rusty wrench into a knife or the time he made a folder out of a bullet — but he too took on the challenge of making a knife from aluminum foil.

Watch 'The KA-BAR Story' Series


KA-BAR the company is celebrating its 120th anniversary on April 29th. In honor of its amazing longevity, KA-BAR dove deep into the history of the brand — from inception in the late 1800s all the way to today.

This deep dive culminated in a four-part documentary series released over the past few weeks on the KA-BAR YouTube channel.

These four videos are exceptionally well-made and track the company through the decades as it responds to major events in U.S. history. KA-BAR got some actors to play historical figures in the company that really help you visualize the company.

I wrote my own brief history of the KA-BAR brand and a closer look into what makes the company so great a few years back. But even I learned a few new things about the brand from the video. For example, I’m glad the company didn’t keep the name Tidioute Cutlery.

I would have liked this documentary better had it been released as one video (since you get a minute intro at the beginning and about four minutes of credits at the end of each video).

Watch Cold Steel's Latest Knife 'Proof' Series for 2018


If you were to ask most knife people what Cold Steel is best known for, they’d probably say those insane videos showing president Lynn C. Thompson and others cutting pieces of thick rope or chunks of meat with heavy metal playing in the background.

While Cold Steel has gone through quite a transformation over the years, bringing some of the strongest folding knives to the market and constantly trying to improve in every way, it will always be known for its over-the-top marketing.

According to legend, they started making the videos more than 30 years ago to prove just how strong their knives were. Cold Steel claims the videos “stunned the industry” with their graphic testing.

Watch Woodworker Create Homemade Knife Sharpener

Sharpening is a necessary evil when you own knives. While it can be complicated to start with, it doesn’t need to be with a little practice.

But, if you’re good with your hands, you can make your life easier by making your own knife sharpener with a few simple items.

That’s what carpenter John Heisz of I Build It did on his YouTube channel.

By using an old oil stone and some plywood, he was able to craft a homemade knife sharpener that you pull through interlocking teeth.

'Knife Kid' Captures the Joy We All Experience with Knives

Viral videos are often lame, but every now and again a video permeates the knife community by perfectly capturing what we have known all along and what the world at large often forgets: knives are awesome.

Behold, the knife kid.

Welcome back. You undoubtedly watched that video at least five times in a row. It’s not your fault necessarily since some videos may be scientifically impossible to watch just one time.

Here’s the back story before we get into what I love about the video.

According to an interview with The Washington Post, 22-year-old Chelsey Ryan was hosting a party Labor Day weekend when she Snapchatted a video of her 5-year-old cousin who was being particularly rambunctious that day.

That’s when the hilarity ensued.

Watch a Buck 110, Leatherman Wave, and Swiss Army Knife Get Made

So much content exists out there that it’s easy to miss something that’s really cool and informative. Even a guy like me who’s paid to notice everything that goes on in the knife world can miss a thing or two. But some things are still cool even after they’re a little old.

Brandmade.TV is a YouTube channel that makes pretty interesting and in-depth videos on how famous products are made — like a Pelican Case, Samuel Adams Beer, and Pyrex Measuring Cup. Although the channel hasn’t put out videos for a year, three of the videos in the archives focused on iconic knives. Let’s take a look.

Buck 110 Folding Hunter

The 110 is one of the most iconic knives of all time and became so prevalent that any knife in that style is known as a Buck knife. The video features an interview with CJ Buck, who’s the chairman and CEO of the company, on the process the knives go through to get to their final state.

Wenger Swiss Army Knife

Remember Wenger? In case you don’t, Wenger was known as the maker of the “Genuine Swiss Army Knife” (vs. Victorinox’s “Original Swiss Army Knife” tagline) before it was bought out by its main competitor Victorinox in 2005. Then, in 2013, Victorinox announced that there would no longer be two separate brands and merged the two together under Victorinox. Although some Wenger designs still exists, they’re under a different name.

Watch Miller Knives Turn an Old Rusty Wrench Into a Knife

They say, “If all you have is a hammer, everything looks like a nail.” Well, if you’re a knifemaker, everything looks like it could be a knife.

Us normal people would see a rusty wrench and think it’s nothing but a rusty wrench. But to Steve Miller of Miller Knives, that rusty knife could be a functional knife with a ton of personality.

In an easy to digest video, Miller takes a rusty wrench and transforms it into a knife you can do some light batoning with, feather wood for a fire, or use as a throwing knife.

To me, the best part of Miller’s videos is the wordlessness. You hear nothing but the comforting sounds of the workshop as Miller does his thing.

Watch Ingenious Knifemaker Forge a Knife with Drill Shavings

I’ve said it countless times before but if you’re not following Steve Calvert’s Green Beetle YouTube channel, you’re doing something wrong with your life.

Steve is a national treasure (if you narrow the scope of “national” to knife community and “treasure” to nominally entertaining). I kid, of course, because Calvert makes some of the best knifemaking videos out there.

He usually conducts entertaining experiments and tries new things when making knives in his videos (like his ‘Murica Knife, which uses bacon, fries, beer, and Tums, and his most-viewed video on making a knife from a cable).

Watch an Old Rusty Knife Get Restored to Perfection

I have a confession: In my spare time, I like to watch knife restoration videos in the background.

It may sound odd but there’s something satisfying about taking a knife from a rust-covered dull piece of steel to a functional work of art.

Now, millions of people know how I feel.

If you’ve been on YouTube in the past week or have visited any knife sites, you’ve undoubtedly seen the top-trending video from Jun Yoshizuki about restoring a $3 knife to its previous $100 state.

Watch with awe.

I saw this video shortly after it came out and it has now garnered more than 11 million views as of posting.

Jun, who is a YouTube personality and chef,  is known for making videos with his American wife Rachel about their experiences with Japanese culture. (He’s also known for making videos with his cat Kohaku in the background.)

On his own YouTube channel, his previous videos also garnered a few million views (including his second most popular video, which also deals with knives) so this isn’t necessarily a rags to riches story, but it’s always cool to see a knife-centric video get some love from the wider Internet.

Watch 500-Pound Knife Get Dropped Onto Used Toyota

If you’re not following the giant robot wars going on across the world, you’re not paying attention.

The team at the YouTube channel MegaBots Inc creates some awesome robots that they are planning to use to battle another giant robot very soon. Throughout the last year, they made the Mk.III robot, which is 16 feet tall, 10 tons, and worth $2.5 million.

So what does this have to do with knives?

Well, at the start of the year, MegaBots Inc teamed up with Simone Giertz — who is a non-engineer known for making awful robots — to make her infamous chopping machine significantly larger with the help of the Mk.III. Take a look.

Because that wasn’t part of the final design, the team had the leftover 500-pound knife that they decided to drop onto a used Toyota from a crane for laughs.

Watch Blacksmiths Create 'Wonder Woman' God Killer Sword

The team of blacksmiths at Man at Arms: Reforged from the AWE Me YouTube channel is back at it again with another creation from pop culture.

With the release of Wonder Woman imminent, the team decided to create her God Killer sword that appears in the new film. (They made her shield in the last video.)

The sword only appeared pretty recently in the Deathstroke comic but it has a pretty interesting back story if you’re into comics at all.

Watch a Knifemaker Forge a Knife in Tribute to David Bowie

“I have no idea where I’m going from here, but I promise I won’t bore you.”

That’s a quote from the late great David Bowie and it’s a creed we should all live by. I guarantee you Steve Calvert of Green Beetle approaches every video he makes for YouTube that way.

Just a few weeks ago, we highlighted his thoroughly hilariously and ingenious video in which he forges the “Murica Knife” using fast food materials like french fries, bacon, and beer. In my humble opinion, his latest video simply titled “Forging a Bowie Knife” is even better.

Watch a Robot Play the Knife Game with a Trusting Human

Everyone knows we should never arm robots.

Robots are our servants and should only be forced to work in the factories, vacuum, and occasionally dance. Unfortunately, there’s always going to be that one person who wants to give robots just a little too much power.

Today, that person is YouTuber Irfon Automation. He wanted to show off his skills so he attached a knife to a Staubli TX40 and programmed it to play the knife game or five finger fillet or whatever you want to call it. Here’s what happened:

Sure, it’s downright impressive that his neighbor (or sacrificial lamb) did not get his fingers cut off, but I don’t think it’s quite the best use of a machine that’s known for doing mundane work like precision lathe loading and unloading (whatever that means).

Watch Miller Knives Create a Folding Bullet Knife

Miller Knives is at it again.

The Miller Knives YouTube channel is well-known for making an array of knives, including transforming old pieces of junk like hammers into functioning tools like a throwing ax. In fact, Miller Knives was featured in a recent post looking at 12 knives made from old pieces of junk.

In a video released about a month ago, Miller took a 100% inert (let’s stress that) .303 British caliber bullet and in under five minutes of video time, transforms the bullet into a functional knife.
