  1. Sorry, Austin. All data reported only shows width at machi and yokote. The best advice I have given in the past and will continue to give is to handle originals. As many as you can as there are many variations in blade geometry which ultimately translate to the interpretation of the polisher. Museums are one way to see originals but even better Japanese sword trade shows (token kai) because you get to hold the swords in your hands.
  2. Tall order. Consider that a katana is more than 2-dimensional object in both length and mass. I will follow with interest.
  3. Here here. And this goes to the administrators/moderators that through hard work have made what happens here possible.
  4. Thanks, Skip. The construction clue fits in the puzzle. A long distance from Nijmegen to Vehmaa but it could have happened.
  5. Thank you all. That's an interesting description although Google translate is limited. Thanks, Skip. Jeroen, if at any time you have the chance to see it I would love to have some pictures of it. The construction is reminiscent of the Vehmaa, Finland sword.
  6. Thanks for the comments. The incomplete circle brush stroke is used to represent "mushin." Not kanji, just a simplified interpretation. For the saya I used gold leaf then lacquer. I tried as best I could to make it look like ink. Funny how the circle is incomplete. It likely has a significance. I find that is easier to reach this "mushin" state when I practice archery. Some shots feel just right. Unfortunately not all shots turn the same way.
  7. This blade is a hira-zukuri wakizashi made from homemade steel. 18” nagasa. The steel was made in a traditional bloomery furnace and divided in two blocks. The first billet was used for the core of the sanmai sandwich. This metal was carburized. The other block of metal was compacted and then folded to create 360 layers of metal divided in two to make the jacket of the sanmai. 360 degrees represents a full circle which goes along with the “mushin” topic which I tried to reflect in this blade. “Mushin” literally translates to -no mind- as in the flow of things that happens to look easy becaus
  8. All I have is this reference drawing: The one on the top. I have no further info. Sorry.
  9. I am talking about actual photographs and not drawings and I am referring to the Nijmegen sword with the serpent pattern.
  10. I brought the camera with all the intentions to take a bunch of photos but I was lost in conversation most of the time and so I only captured a few images.
  11. Sorry to miss the opportunity to meet you, Jim and I hope you heal fast! It's was a great weekend seeing and talking to good friends and making new ones.
  12. Grinding away. It is supposed to be an animated GIF but obviously I couldn't make it work here.
  13. This has been one of my interests for quite some time. I would love to hear about your process and the software used. I was trying to upload an image but is not working. I'll try later using a smaller file.
  14. Well... I'm in too. See you guys there.
  15. Exactly as Lee put it. Let's just make sure we get the terminology correct. Alan William's paper describes the chemistry as being "hypereutectoid" and to be more precise most sword were around 1.2% and some up to 1.6% and no higher. The term "hypereutectic" is different and means a lot more carbon but the point Lee was trying to make is that since the publication of that paper there has been a general assumption that hypereutectoid=crucible steel. This is wrong. Acepting that would be the same as saying that every tool steel made these days is crucible steel. There are other ways to skin the c
