That file, though...
With the first blows from the hammer, it crumbled like old cake, so I had it checked. It has a carbon content of about 1,5% and a weird dendritic structure. So, grinding away all the rust marks and structure, and gently tapping at a relatively low temperature with a really small temperature window it was. Used a wooden mallet for that. It took me two days to get it to move at all, and a break of three month to recover from the inflammation in my elbow to weld it in between the leaf spring sandwich construction. And at first it didn't want to weld. Drove me fecking mad. But it eventually worked out, after I messed up the first piece. Forged some kind of animal head to the handle.

The grind is a high convex bevel to almost zero. Almost flat, to be precise, and polished in the edge. The blade is really resilient, and selectively triple-tempered. The edge is really hard, I estimate it at some 62HRC, the middle is soft, the spine is also tempered to an estimated 52HRC. It throws sparks off a flint and a ferrocerium rod. It is rather thin at 2.8 mm, but can be bent to almost 50 degrees.
Length is some 102mm, the CoB is on the index finger.
The fascinating thing is that I learned a lot in the process (and as I said, I failed first), and that it is a bit of a playing with undereutectoid and eutectoid steels. It does look like any old ren fair knife, but it is not.
There actually was a huge learning curve involved. Also, the knife is a part of my own story. I intimately knew that fox relative, I found the steel in nocturnal woods under a sickle moon, and I bled and suffered for the knife. I made my sacrifices for it.
It is the sharpest knife I ever made, and you guys know that I am my own worst critic normally. I am almost a bit scared of it, even though one can always do better. That is not my point. It is not perfect, it is not better than my Casström. Well, maybe it is far more slicey.
But it is a myth in itself. A piece of magic, maybe.
As a kid, I wanted to find the magic sword, as a lot of kids do. And as an adult, I asked the forest. I have shown you some of its answers on the blog over the years. It has been a weird, but interesting journey, and about some of its answers I would not talk. No offence meant, but most people simply could not understand.
Thing is, the magic sword will no longer smite the dragon. The symbol of the time is not a symbol of chivalry or heroism. The symbols of our time are the tank, the whip, the Credit Card- and the extermination robot. All introduced by the dragons of our world, cursing mankind every single day.
The forests are dwindling. Wildfires rage.
But deep below, from the mycelium, magic sprouts. It lingers eternal. It is patient and alien. It sometimes looks really profane. Like a harsh, hard truth, sometimes.
But never forget: It is invincible, because it is infathomeable, because it is indomiteable.
I will die sooner or later. I will rot. But I am a part of the magic.
I am indomiteable.
Become magic.
