Diamond Wood Wine Key Hinoura and this can be seenProduct Description Detailed Specs Measurements This is one of the nicest wine keys I've ever had the pleasure of using. It's similar to a Laguiole style wine key, but is made in Japan and from Japanese steel. The foil knife stays sharp for a long time, the movement is tight and precise, and the in hand feeling is very luxurious. Length: 120mm Height: 30mm Width: 15. 9mm Weight: 104g
