My grandfather had this thing called the bear claw! It was basically a strip of pointy plastic tines and it fit over an out-facing wall corner.
I found myself with a back scratcher in every room as I got older until I learned that the reason my back is constantly itchy is because my fine back hair.
I bought this thing called The Man Groomer which is basically an extendable back shaver, and now I don't use back scratchers anymore... Honestly a humongous relief from needing to scratch my back like 75 times a day. Now I need to scratch it zero times.
We have been well aware of this type of crystalline structure for... I don't know a century? Ferrite anybody? And magnetic heating/cooling are child's play concepts.
The edge is just a little rough after the removal of material with the wheel, the hone grooms the metal so the grains align roughly in the same direction. It also "peels away" ragged and folded edge grains.
The hone takes it from a sharp but rough edge, to a razor sharp edge.
The hone is also the best tool for quickly refreshing the knife edge without having to sharpen it on the wheel. Just 10 seconds before any major cutting.
I bought a Rada Quick Edge at a thrift store for $2.
Was always taught my my metal-smith grandfather how to properly care for and sharpen knives, but when I tried it out on a knife I cared little for, I found it was such a shocking difference in efficiency I couldn't help but notice.
It completely changed my relationship with knives and knife care, which was so helpful for me because I cook everything from scratch and whole ingredients. Everything, so having good knives is not kids-play for me.
It made me discover that for me, using a quick sharpening wheel and a hone gets my knives beard-shaving sharp in less than 30 seconds. I could never go back to the "right way" and I firmly joined the "dark side" of knife ownership.
Yes they destroy knives with some aggression, far more than traditional methods, but in the forensic audit it has saved me hundreds in a literal way, and hundreds of hours laboring over sharpening stones.
I no longer need to pamper knives, I buy cheap German steel chef knives on sale for $5-$20 and I throw them out in 3 or 4 years. I'll never go back. All the hysterics from knife "gurus" on YT be damned - in my personal cooking world where I have 10,000 Km on my knives and cutting board, I could give two shits what they think. Nobody better ever give me a $300 knife for a present because it's going back in the box.
Dual-wheel sharpener and 14" hone is all I'll ever use from now on.
The way I have done it for the last several years and it has brought me amazing new dimensions of sound experience...
Find an artist that you like, look them up and find out who produced the album and other group members.
Then do a little Wiki research into the discography and solo work of each of those performers or producers.
Follow up on interesting threads, and you'll be exposed to all kinds of amazing new stuff.
Although I'm definitely out of this listening phase now, an example that worked for me was I got very obsessed with Talking Heads band. Looked them up and found out that Brian Eno produced them.
Started to notice from other bands I looked up that Brian Eno was mysteriously involved in so many of them.
Started to look into all the bands that Brian Eno produced and worked with over the years, and then started to look into the music of Brian Eno.
Starts to give you a realization that the true talent in a band is generally not the performers, but rather the veterans with decades of experienced who guide them.
Another example is Buckethead, started to see this dude buckethead appearing on literally hundreds of different album credits! Did a lot of research into the guy and the various bands he's worked with, and that opened hundreds of new experiences to me.
This comment is getting a little outside of my original point, which is to actually do some research on your own, go out and find the lesser-known works of artists you love.
Basically just follow different Wikipedia links, and then when you find an album in a discography that you think might be interesting, look it up.
