Katsuobushi (aka bonito) is dried, fermented and smoked tuna and it's incredibly hard. It's so hard that it's possible to fashion a shiv out of it.
To do so, you'll need a mandoline, an adjustable wrench, a metal file, a vise to hold it in, an oven, a whetstone and some patience. YouTuber kiwami japan shows the way.
You'll not only get a dangerous weapon out of the deal but also a big bag of bonito flakes (which are great for making your food look like it's moving).
Billy McNeely of Canada's Northwest Territories was scratching his back when he noticed a pointy protrusion. Turned out to be the tip of a 7.5cm knife blade that was stuck in his back. For three years. Back in 2010, McNeely was stabbed in a brawl following an arm wrestling match. Since then, his back set off prison metal detectors and he's had pain, but he claims that physicians told him it was nerve damage caused by the injury. From BBC News:
But this week, McNeely, 32, was scratching his back as usual when his fingernail caught on something. His girlfriend took a look.
"I told Billy: 'There's a knife sticking out of your back.' I was scared. I was ready to pull it out with tweezers," Stephanie Sayine told CBC News.
McNeely is considering whether to file a lawsuit against the local health department.
This gorgeous knife is elaborately engraved with scenes replicating Dore's illustrations to Dante's Inferno; I'm not clear on whether this is a knife or a razor (which is technically a knife, I know) -- the forum is called "Straight Razor Forum," the poster calls it a "knife," and the piece does not resemble straight razors or pocket knives of my experience. I'm sure that when I check this post tomorrow morning (it's queued up to go live after I go to bed in London) the comments will have settled the question in excruciating detail.
The theme was Dante's Inferno and the images are based on Dore's illustrations for the book. The toughest part was that I had to alter the images to make them fit the format of the windows. I had to make the altered images still recognizable as the classic Dore illustrations.
The "frames" are sculpted and the images are bulino engraved. The scenes on the hidden panels were also bulino engraved. The knife was made by Joe Kious of Kerrville, TX.
The CardSharp 2 from Iain Sinclair is a folding utility knife that turns into a credit-card object when it's not in use, suitable for storing in your wallet. It's a clever little design, unlike a lot of credit-card tools that leave you with a rectangle of plastic in one hand and a tool in the other, the "card" folds around to become the handle.
The Deglon Meeting Knife, designed by Mia Schmallenbach, is a set of sculptural, nested knives (priced, alas, as sculptures, at $600 for the set). The proportions of the four nested knives -- paring knife, carving knife, chef’s knife and filleting knife -- are "determined by the Fibonacci sequence with as its base the average width of a hand."
Gerber is one of my favorite multitool companies; I like the fact that they're always experimenting with clever (but rarely gimmicky) ways to extend the functionality of pocket tools. Case in point: this forthcoming "Steady" tool, which incorporates a tripod with a standard camera screw-mount. I really miss carrying multitools wherever I go, but the combination of insane, overreaching anti-knife laws in the UK and frequent, expensive airport checkpoint confiscations (I forget stuff sometimes!) has put my multitool in dry-dock beside my desk. The Steady is due in 2012 -- maybe by then we'll live in a world that acknowledges that banning edges from public places isn't necessary or sufficient for safety.
