Wow, pretty amazing. I wonder how long the fuel cell will last? From my limited reading, they rely on precious metals like platinum for a catalyst- which would eventually need to be replaced.

I don't think he's correct when he says that the price or value of precious metals like gold and silver retain their same value throughout time. Nowadays, gold is a precious metal which means it has only ornamental value. In the days when the gold coin was around, it was used as currency and thusly they needed a lot more of it. If you smelted down the old gold coins to make a piece of jewelry today, I'm pretty sure that it would cost less to make a golden necklace out of coins than what the same necklace is being sold for now. Maybe the karat of the gold matters significantly, in which case gold has inconsistent value even within itself (nowhere in the video does he mention karats of gold so I'm assuming he means fairly high-quality gold).

Happy Birthday, ant, and many more. You'll probably outlive us all, because I hear downvoting is the key to longevity. If you're willing to burrow all the way down into my coffin you can have my gold fillings. If you can move a rubber tree plant than extricating the precious metals from my mouldering remains should be a cakewalk. (Cake! Get it? Because it's your birthday! Wheeee!)

Abort! Abort! Mission Abort!

Attention everyone watching this video! Beware of mister edges and other hucksters like him. The belt sander that he is using to sharpen that knife should NEVER, I repeat- NEVER touch your steel. Any process of sharpening that produces SPARKS is far FAR too harsh for your precious metal.

For the sake of our knives please please PLEASE spend some time reading this article: Knife Maintenance and Sharpening. Chris Ward gives the best treatment of knife sharpening that I've ever read. He really knows his stuff.

I wish I could downvote this video. While I agree with much of the info in it, the process that he is using shows that he has no respect for the knives. He is only interested in doing as many knives as possible to maximise his profit. We have several grinders like this around town and I campaign to local chefs to avoid them. If you can sharpen a knife in 15 seconds, you are definitely doing severe damage to that knife.

This idiot has just detempered the steel, he may cause microfractures in the blade, and he has taken off way WAY more of the edge than he needs to, all of which leads to a shorter lifespan of the knife.

If he's like the con artists in this city, it's likely that he's put too acute a bevel on the knife as well. Why? Because knives that are too acute SEEM sharp when you first get them back, but the steel isn't hard enough to hold that edge. The result is that the knife becomes dull again very quickly, and the knife "sharpening" service gets called back sooner, which means more profit for them.

This sort of thing really makes my blood boil. It's just close enough to being correct that it is very convincing, but it's all a scam.

I use a whetstone and Arkansas stone to sharpen my knives, but I have had several knives severely fucked up by idiots just like the one in this video.
