...makes you wonder if some of the old swords you see around ever looked this alive.
Have you been to an excellent museum (the Met springs to mind), the S.F. Token Kai, or Japan lately?
The Japanese system of becoming a licensed togishi (polisher) requires a
greater amount of time (on average, it varies) than becoming a licensed swordsmith! This is because not only does the Japanese polisher have to have the skill and ability to shave off the absolute least amount of mass necessary to reveal the fresh steel underneath, and to shape and contour absolutely every plane and line and surface perfectly while leaving the grain (and visual metallurgical activities) completely open, WITHOUT using destructive etches - but he has to do all this with a comprehensive and expert knowledge of the entire history of Japanese blades, including all of the major and many of the minor schools and styles, so as to best complement the original aesthetic and intention of the work.
Extant antiques in fresh polish from as far back as the early Shinto era (~1600's) can look like they were made yesterday, if they have been properly maintained and carefully restored, and even some blades from the Koto period (~1100's or so is the time I'm particularly thinking of) can look superbly "alive" and fresh even though they are likely a slight degree slimmer than they originally were.
A good Japanese polish will last 150 years or so if the blade is not used and properly maintained. This figure comes from actual examples, the history of which are known, existing with polished that old and more that don't yet need a repolish. We are fortunate in that many fine nihonto have been expertly preserved and are essentially flawless and perfectly clean. Nowhere else has the same standard of preservation yielded such examples. It's sad, because fine western arms and armor are much rarer, and are *always* in a state of disrepair and patination. Many people have a mistaken impression regarding a perceived "crudity" of western swords, partially because they see corroded examples excavated from bogs and rivers and damp attics and who knows where else.
All this is just to say that not only do many fine antiques exist that look "alive," but many of them are at a level of polish that the polishers of Mr. Yoshihara's work aspire to. Which is to say that the very best national treasure polishers (i.e., the POLISHER is a national treasure - as are the blades he is working on

) of Japan are likely to be spending more time restoring and preserving priceless antiques than to be sprucing up beautiful new masterpieces - although many do both. And from a blade perspective, although many Gendai (modern) smiths have reached astounding levels of beauty and expression in steel, there are many people who don't believe that we will ever match the refinement of masterpieces from the Kamakura era. I personally believe that it is only a matter of time before such blades can be replicated by a particularly gifted individual, but it shouldn't even matter, because modern works are often extremely beautiful in their own way...
...Oh, and hi y'all, I'm new here. I post a lot of Sword Forum, myArmoury.com, and the Bugei forums.
