kaigunair Posted June 14, 2011 Report Posted June 14, 2011 As one who appreciates gendaito/gunto swords due to the era, I frequently ran across sellers who seem to have lots of these blades in good condition. Later on I learned some sellers use an "acid wash" to clean up these blades instead of having a togishi polish them. One by-product is that the whiteness of the hamon is lost, becoming a more mirror finish, while the rest of the blade looks white, sort of a reversal of the hamon/blade. I was wondering, does acid washing permanently damage blades? Does is permeate beneath the surface, or is it just some sort of top layer oxidation? Thanks in advance. Quote
cabowen Posted June 14, 2011 Report Posted June 14, 2011 Normally, it can be repaired by a proper polish....It is always a good idea to clean such a blade with a neutralizing solution to be sure the acid is stopped.... Quote
kaigunair Posted June 14, 2011 Author Report Posted June 14, 2011 Thanks chris. Is there a good explanation or forum thread that explains why the hamon turns clear and the rest of the blade white? too bad the blade can't just be soaked in a base solution to "reverse" the acid. with the cost of a polish, most gunto/low quality gendaito are for all intents and purposes irrepairably damaged...

cabowen Posted June 14, 2011 Report Posted June 14, 2011 It happens because the two areas are of different hardness and the acid corrodes them at different rates... Yes, is indeed a sin.... Quote
