Kitchen knives 

Shimomura produces the Verdun knives which are known for their excellent price / quality ratio. The Verdun knives are made with Japanese steel (stainless molybdenum vanadium) with a hardness of 57-58 Rockwell and therefore remain sharp for longer than comparable (often more expensive) knives. Also these knives do not suffer from hygiene problems, because there are no pits in the handle.


The metal industry in Sanjo is very well known. The history of the smithies in Sanjo can be traced back to the year 1625 (more than 390 years ago). Before 1625 the area around Sanjo area was a rural area with a lot of nuisance from frequent flooding of the Ikarashi River.
The governor of the time of the "Seibei OTANI" area wanted to develop the area further. He invited some nail producers from Tokyo to start a smithy in Sanjo. In addition, he raised many dams that protected the area from the floods and served to irrigate rice fields. At this moment, the metal industry in Sanjo is known for its production of specific types of steel for kitchen knives. The best and sharpest nail clippers come from here
