I went down the rabbit hole of the micro biome. We live in a symbiotic relationship with a ton of different organisms, particularly in our GI. They actually do a lot of the digesting of our food, and give us things like anti inflamitories. Another interesting thing that I read is that the nerve cluster that runs trough our digestive tract that connects our brain and our organs contains more nerves than our spinal cord.

It is amazing that considering the "other than human" content we carry around everyday, that we don't get sicker more often. I imagine it's like Nixon and Breshnev, a detente of sorts.
Like congress. It's best if no party has an absolute majority because that's when things go south, kinda like in real life :D

Today I had a rare full day of blade work. I etched 2 wootz razors, and then made a good amount of damascus. I also finished the forging for the damascus kitchen knife that I've put WAAAY too much time in. The kitchen knife is for a trade and the level of complexity significantly exceeds the value of the trade but I figured if I'm going to make something, I may as well make something I can show off :) I also made 2 damascus razors from some complex twist that I worked on for a while.

I try to make damascus in large billets even if I need only a bit. That way I can stock up on forged blanks and ready to forge damascus bar. That's a lot more efficient in the long run.

Also I learned that I still need to rethink my wootz etching. I had one razor turn out very nice, as expected. And the next one turned out completely stunning. But when I etched it again, the contrast was a lot less. Then I completely sanded it clean again, and the first etch was great and then the next one much greyer. I didn't get to stop it at a single etch because there would be some black smudges.

But that's still a good sign. I do understand the heat treatment and forging process. Now I just need to optimize the etching process :)

There is always ways to improve the quality of our workmanship, and we are our own worst critics. I have a big smile, as you seemed to have made it far enough past a hurdle that you are confident in your process and knowledge. It’s a beautiful place to be. At some point I’ll be looking for your footprints.

Oh I Use nitric acid. But it's a matter of figuring how long, and how to get rid of the oxide dust covering the carbides without a) smearing everything until it is black or b) abrading the contrast away.

I'm going to have to re-do the etching anyway so I'll take pics to show what I mean.
It doesn't help that this is spoken for so I am limited in what I can try.

I bought a new ingot from Niko, with materials to melt one myself as well.
The plan is to forge out his one using his method and temperature windows, and then making a bunch of different shims. They will all be heat treated using different soak times, with / without antiscale coating, different geometry, different etching methods, ... in order to figure out the optimum.

Kinda like Daniel O Connor told about in TX when we were there. He uses stock removal, all on blades with identical thickness, and for his heating set-up and blade shapes he has figured out the heat treatment down to a window of about 5 seconds in order to create the very best hamon effect. And he did it by just doing the same thing over and over with small variations to find the sweet spot

LOL, the good ones always have the mind numbing science behind them. The long slog of heat treating just one more tile...

Their notebooks are very difficult to argue with content.

This was hilarious. Tyson's the one humbly complaining he's too old for this, but Jones is the one who looks like he'll die from exhaustion if a heart attack doesn't kill him first. I love that Tyson wants do do this again in order to be able to give more money to charity while entertaining fans.

I see that they are going to have break dancing in the Olympics.

At lunch today myself and a few coworkers decided we should refresh our break dancing skills.

One of the troubles I have is one of the meds I take is a banned substance for the Olympics.

I may have to talk to my doc and see if there is a good alternative! :)

I'm trying to picture you spinning on your head...

Then again, Charlie's shop must be under some magical protection. Because Paco spent 4 or 5 days in there and didn't injure himself :p

Wow Tim, first figure skating and now break dancing, you are much more athletic than you appear. Break dancing is pretty close to gymnastics when it comes to strength and mobility. Soon I suppose ninja warrior and parkour will also be at the Olympics. While I appreciate the level of strength, endurance, and mobility required for these activities I can’t say one way or another that they are practised in that many countries.
