Your terminology is wrong. This is not "sharpening", it's "honing". Eventually, the knife will actually get dull, meaning the edge is not just bent, it's flat. At this point, honing no longer works, and you have to actually sharpen the knife again with a real sharpener.
As long as we are talking physics, I have a great one for a hard to open jar. Take a heavy handled table knife and strike the jar's lid at an angle, in the direction the jar opens. It will break the seal and start the lid opening. Three or four small whacks should do it.
From experience is that one of those ceramic fuse from fusebox is the best. The surface is smoother than in those sharpener stones.. You can get a knife as sharp as with leather or diamond vile. It just takes VERY much time…. But sure is worth it
I am Wolfie Horn and I am 5 years old. I love your videos and I have a question. Can you please make a video about: How Uranium is a rock that became a bomb?
This is barely chemistry, it's only the nature of the ionic bonds of the ceramics and the metallic bonds of the knife, but the motion, friction, and everything is simply kinematics and forces, in other words, physics
OR you can just use the back of another kitchen knife. They're always (given the same knife or at least fabric/manufacturer) hard enough to sharpen your blade, even if you have ceramic knifes and I've yet to encounter a kitchen knife that hasn't a 90° "edge" on the back.
One question: If you put a charged solid next to a water jet, the water jet will bend towards the charged solid.
Is the explanation for this because of the water-dipoles who align themselves or is it because of the ions in the water? I would be very pleased, if there would be someone who knows the right answer and who wants to share it 🙂
I tried this with my Pocket knives IT WORKS !! IT FREAKIN WORKS!!!
FUCKING genius! you know how many of my knives I just throw out….
I wantet do scharpen my karambit not a kitchen knife
http://www.ebay.co.uk/itm/two-stage-knife-sharpener-uk-/262707679593?hash=item3d2a991169:g:UvgAAOSwal5YH040 This s quicker and easier
🙁
Thanks

That knife is from ikea… I have it

I thought that everyone already knew that "truc. (sp?).

I swear someday ill edit all of your videos with my face

This was great.
Ketchup on the bottom of rusty, or tarnished copper bottomed pans!
Sharpening… or honing?
will that damage the plate eventually ?
"but where's the chemistry…….wahhhhh"
–quit whining people, it's a cool hack.
Not really "sharpening a knife without a sharpener". More like The sharpener you didn't know you had".

Or you could just go into your backyard and grab a rock

This is neither chemistry nor a hack. This is just pathetic.
As someone who used to manage a knife store I can tell you this life-hack is legit =)
This life hack has nothing to do with chemistry. Physics, yes, but not chemistry.
What a great idea!
cool new series, keep it up

Underwhelmed on the chemistry side, but interesting nonetheless.
