New type of bulat (wootz) from Ivan Kirpichev.
Got new pictures from Ivan. He goes forward with his experiments with bulat and this is something new as I understand.
Left blade is new Ivan's bulat - on the right old persian blades (bulat or wootz or damascus steel). So he think he recreate that pattern. This is how he tested it Scratching glass Whittiong saw chopping nail Than it was put on anvil and hit by steel square slightly and then harder and harder. Then battoning nail. Then bending until it was broken (Ivan sad that angle was bigger - he just did not manage well to bend it with one hand and make picture with another. Last he sharpen tip of the broken blade and try to nail it into the anvit - no cracks. According to Ivan came up with new technology, which he does not disclosing so far. He ask me to present it here because he neew feedback and comments now after he able to recreate persian pattern he want to know what everybody think about it. Thanks, Vassili. __________________ nozh2002 |

I tried to translate it briefly - it is about his testing, I say torchering this metal.
------- He has some website. http://kirpi20.narod.ru/ But I am afraid it is slow. I try to help him with this. You may find some of the pictures here: http://playground.sun.com/~vasya/life.html http://playground.sun.com/~vasya/Bulat-Kirpi-01.html old bulat http://playground.sun.com/~vasya/Bulat-Kirpi.html He give me few blades to test (I send him back some exotic wood in exchange, this is not bussiness deal) and I made knives out of them: http://playground.sun.com/~vasya/knife74.html http://playground.sun.com/~vasya/knife73.html http://playground.sun.com/~vasya/knife78.html ----------------------------------------- If you like to buy - ask him directly - kirpich20@rambler.ru. I may help with translation, but I am not selling them or something, I don't know anithing about prices etc... I am just facinating with this metal and try to help him to be known here - he lives in Russia in small town near Tver, he need some help. Thanks, Vassili. __________________ nozh2002 |

Let me try to translate it. Sorry, I am not quite good in Metallurgy terms as well as in English in general...
Here Ivan demostrates different bulat structures by different etching. One kind of etching exposes carbide scales and another dendrit steel threads. First is etched in Kvas - kind of nonalcogolic rye beer - traditional russian beverage. Second is some strong acid whch too strong to show carbide scales. Ivan states that - "Blade has midcarbon steel matrix reinforsed with dendric threads and carbode scales. Fist adds strength and flexibility and second adds cuting power."

Hi Vassili!
The pattern in the steel looks very good! How ever - that kind of testing doesn't impress me too much. In most of the workshops is tools for cutting cold metal, they call it cold chisel(zubila). Photos doesn't show the sharpening angle! A properly made blade should pass these tests in similar way. It's not tricky to make a blade that cuts iron. More difficult is to make a blade that cuts iron and wood. And even more difficult is to cut wood after iron. But after all - why one must cut a steel/iron with his knife? What I would like to see is some cutting tests(rope, wood etc.). A good test is to give a test blade to some hunter. As I understand, mr Brick asks what kind of tests he should do so here it is! That does not mean I don't like it (give him "bolshoi privet"). I like it and would like to have a piece of that bulat, if possible, to make a knife. BTW: once I tested my pattern welded blade hammering it to 25x25mm square iron(not from corner) with 75kg powerhammer That blade doesn't cut much of anything but iron __________________ T?nu Arrak |

thank you for response.....
nice etch in ferric cl I had never heard of a beer quench....... hahaha.....I thought that was only for the smith here is a small blade I did recently http://www.knifenetwork.com/forum/sh...ad.php?t=29995 and I used nitric acid for the etch........ actually it is more accurately " Nital acid".... i've used a mix of nitric acid and rubbing alcohol and distilled water... I found this will give good clarity to the pattern in the steel ! shortly i'll have a few more knives to post.... Greg ps..... thank you for the wonderful pictures |

Well, cuting ability of wood is out of questions we are not in circus, making tricks. Thickness of the blade really easy to differ from thickness of metal chisel, just look at the bending test - it is thin and it has fine edge it is clear from the pictures also - check marks on the iron square. It is flat gring and thickness of the blade visible. It is obvious.
You should know Russian after being part of the USSR and Russia, so check my website with all oak cutting tests I made for bulat blades - it is all there. Thanks, Vassili. __________________ nozh2002 |

2 Greg
Nice knife. On my website I am knid of supporting bulat making by posting different articles about bulat. I have two from Achim Wirtz. http://playground.sun.com/~vasya/Bul...m.html#English http://playground.sun.com/~vasya/Bul...s.html#English and some in Russian from Fursa and Kirpichev. http://playground.sun.com/~vasya/Bulat.html http://playground.sun.com/~vasya/Bulat-Kirpi.html If you like I'll be glad to post there some article from you? In English and I'll translate it in Russian. What do you think? ---------------------------------------------------------------- Here my knives made from Ivan's bulat: http://playground.sun.com/~vasya/knife82.html http://playground.sun.com/~vasya/knife78.html http://playground.sun.com/~vasya/knife74.html http://playground.sun.com/~vasya/knife73.html Thanks, Vassili. __________________ nozh2002 |
