The final knife transformation is complete. The angle guide polished off the patina so I gave it a soak in phosphoric acid gel and it matched very well, and added some nice irregular patina texture.
The dark spot on the edge is probably due to either inconsistencies in heat treatment.
The edge being thinner tends to heat up to a higher temp.
But it at least shows that despite being a $25 knife it is heat treated high carbon steel as advertised.
It's actually a quality knife, but the sheath is absolute the hottest of garbage and I will enjoy making a replacement in a few months.
In several years I will definitely get into blacksmithing and metalworking as the medium definitely speaks to me.
So does wood. And they speak together wonderfully as mediums of course.
and leather.

>What does this have to do with anything?

I am a "universal artist."
I treat every aspect of my experience as a creative medium.
Everything to me is art.
And so I just endlessly pursue and enjoy immensely rich creative mediums for the beauty and meaning they reveal.
Just go forth and find a bunch of awesome passions and hobbies and fill your life with them and your life will grow super rich.
The more things you find to love about the world, the more you give love to the world, the more you win.
"Find your joy" is actually profoundly based advice.
