Workshop: Restoration
Paul Kosta held a workshop at his home on the restoration and repair of Japanese swords. This was intended to enlighten collectors on the extensive processes involved in the restoration of a Japanese sword.
This was a very interesting and detailed event. Diplays were set up to show the various equipment and supplies used in restoration, as well as the tools needed when polishing swords by professionals and various other supplies needed in making habaki, shirasaya, urushi scabbard repair, fittings replacement, tsukamaki and other skills.
The workshop covered the importance of first being able to look at and identify a sword before proceeding with any restoration. The sugata, hada, hamon, mei, nakago and yakiba all have to be taken into account to appreciate the techniques that will be utilized. The characteristics of the various swordmaking schools have to be researched and the period identified. To kantei a sword takes many years of study, and is essential in most aspects of restoration to preserve the original identity of the sword. There was brief discussion on these traits that need to to be identified.
The workshop then went into depth on the work of the togishi (polisher) and the various stones that he has at his disposal. A decent set of stones can take a lifetime to accumulate, and can cost a huge amount. Discussion took place about the various qualities of the stones, and the order in which they are utilized. Examples were shown of many grades of natural stones, and the other supplies that are used in polishing.
Also covered in the workshop were the making of habaki, and shirasaya. Tools and supplies were shown, and discussion took place on the correct techniques and methods of use of the specialized impliments used in carving the shirasaya or saya.
The workshop ended with a talk on urushi and its use in laquering the saya, and methods of application. The attendees were allowed to inspect the tools and supplies and ask questions. Various blades in different stages of polish were also shown and discussed.
This primer on restoration is hoped to be followed by more talks in the new year, with the aim of demonstrating the safe, responsible and correct methods of restoration, and to promote an understanding of this Japanese art.
