Why don't you crawl back to /pol/?

For anyone as retarded as OP, turning a bike into a sharpening station is a century old thing, pic related. People who did that job went from town to town in their bike, and along with resharpening knives they usually also carried repairs for things like umbrellas.

It depends on the grit of the stone and on the skill of the worker. Besides, a knife that's been ground down more than strictly necessary is still better than a dull knife. Also, if you're in rural nowhere, money are tight, and that's your only option for knife sharpening, then you'll take it.

Now that I think about it, a spinning grinding stone is still a method in use today. Tormek are stupid expensive too.

I genuinely don't understand the hate. This is innovation. This is survival. You have people who are making a business with nothing but a modified bicycle, and skill. This is fantastic.

Then you have people like you, calling them niggers, and trying to rope in other people who are so low in the society they live in, they are trying to make a spectacle of a society that has nothing.

You've done nothing but put yourself on display as the insufferable faggot you really are. Good job.

People have been sharpening knives like that for a long, long time, anon. No, it's not going to turn your head-hacking machete into a razor blade, but it'll do a good enough job.

The stone isn't spinning like it would on a bench grinder. A foot-powered grinder probably barely spins fast enough to send sparks. An old farm I used to rent used to have a hand-cranked bench grinder. Did a serviceable enough job sharpening lawnmower blades.
>>
>>2974625
it does send sparks though there is a gear ratio and they like to crank the peddles to show they're working hard it's a showmanship of sorts at the expense of spectators knives

It was a psyop from the get go, it was meant to give the site a bad reputation, and people fell for it. Hell, I did it too. Good thing I got out eventually. Despite being a radicalization hub that programs people into shitting up the public discourse so much that pedo billionaire are left free to steal and rape with impunity, I wouldn't mind /pol/ so much if it didn't spill everywhere and jannies at least bothered to clean the mess up when it happened.

I actually watch a ton of those videos late at night before falling asleep on the couch. It's both interesting and horrifying. They can do some of the most crazy shit with nothing, and do a decent job of it at times, but also can't be bothered to make things even slightly easier on themselves... It's like they're borderline geniuses and complete retards all at the same time.

Sorta. /b/, /pol/, and a handful of others really got the medias attention (shootings, flag finding, pizza, whatever).

The public doesn't understand what an image board is, let alone a specific board, so the domain gets thrown around the headlines. Thank god the wiki page has board specific examples, etc. I do agree with you though, keep pol on pol.

Blacks have better DIY culture. Westoids just buy and replace, or hire illegals to build something for them.

Is this AI bullshit? What's making that grinding wheel spin? The pedals only make the bike wheel spin, but the bike wheel isn't connected to the grinding wheel by any kind of mechanism.
>>
>>2975299
You can faintly see a clear looking belt (vinyl tubing?) of sorts coming off the bike tire and going up to the spindle for the grinding wheel. High sfm from the bike tire to a small pulley would make the grinding wheel spin at a recently high rpm.

>>2973853
Short answer is yes.
Longer answer is that scissors and kitchen knives are consumables, in most households. If you have good knives, you'll also know how to sharpen, or at least find someone to sharpen them, correctly. If you don't have good knives (aka 99% of the population) then an itinerant knife grinder will do the job fine for no effort on your part.

it's funny to watch these "flying machines", they could be like parade floats in any other case. but then you realize they have the ego to believe that it's actually going to fly, as well as that "whitey wants to keep us down and have the sky to themselves", and then it becomes less endearing

He took parts and pieces he had around him and put them together to make something he could use. That is way more innovative than you've probably ever been.

Same as everything else - from other niggers. The problem in these places is not really getting tools or materials, it's that you have to steal them from others faster than they're stealing from you
