That is a beautiful knife. The reduction is unreal, it's hard to imagine beating down a piece steel that much.

This is a photo of one of my experimental knives, this pattern just showed up on one side, but I knew I was getting there. When I etched it, I was very satisfied, I believe I have achieved an attribute of some of the old wootz knives where in the man that made the knife signed it so anyone in the know would realize who made it.

The design you can see in this knife is an honest representation of the structure and chemistry of the steel, it was all developed with heat from my oxy-acet torch. The blade started out as a 6 inch round bar of 52100, was drawn down to this size, a rate of reduction of about 98+% at low temp. 1625 f. being the top forging temp. Many thermal cycles and the multiple quench process.

I call this pattern, "Starry, Starry Night" after VanGoe's masterpiece.

The jagged tear indicates that the blade did not break through grain, it followed grain boundaries.  While you can see the larger changes in direction, with magnification you get to see many individual changes of direction. The blade was quenched as close to critical temp as I could manage, Rex stated that the phase changes are indicative to banding, both chemical and structural banding with fine grained martinsite and coarser pearlite. The bands twist among themselves according to Rex.

Ed, Could you tell me what you are seeing in the crack that let's you know it went through the phase changes? Different grain structures?

The age old question on this forum is "How do you test the  performance qualities of your knives?

Welcome to KTO Jose, your work is refreshing to my eyes. Obviously you have used them to come up with your designs.  What steel do you use and do you do your own heat treating?

I greatly look forward to sharing thoughts about knives with you.

Hi Ed! thanks a lot mate!

I use 440 and ACX38 steel for my inox blades, but I also use XC75 for my carbon blades. But recently I have contacted my local Takefu supplier and I think I will be making damasteel, damascus and VG-10 folding knives soon! I have always liked the idea of combining something classic with an exotic touch!

Regarding the heat treating, yea, I do it on my own forge Wink

Good day guys,

My name is Josť Herreros from Spain, on the first place let me thank you guys for letting me be part of your community! I will try to be an active member of your community!

As the titles says I come from Spain. I own a website that can be access from www.artesaniaherreros.es/en/. I did my best translating it but apologizes for the mistakes you are about to read.
I have been crafting folding knives from more than 40 years, now that I am about to retire I would like to show the rest of the world my creation.

Unfortunately, the new technologies are not my thing, I made a three-month course and my kids are helping me with the photos, website, etc. I have no photos of my old and fancy creations that's why I am starting with really basic folding knives, I will try to have my website updated from time to time.

Thanks a lot for giving me the opportunity to join the forum guys, I will try to help and answer everything I could from my experience,
P.S: let me show you a glimpse of my work, I have attached a few images of it.

Best regards,












Josť

How fortunate we are to enjoy the freedom that is lacking in most of the world.
We celebrated this morning shooting targets, irrigating and now just relaxing, hope your day is all you want it to be.

We used your additions to the HEPK tests and they were greatly appreciated, will add some photos of them when time allows.

This is the test blade pictured above, it made 15 edge flexes with no chips, then 4 180 flexes starting with 62 foot pounds of torque, when it  finally cracked. I have sent the blade to Rex and we should be hearing what he can read with his laboratory equipment.
What we know now is that we can see 5 different phase changes in the blade in the crack, it was very strong, tough did all I expected of her. We could have easily straightened the blade and used it again, can't wait to hear from Rex.
