This is a very nice all original Japanese Type 30 bayonet that was manufactured at the Hikari Seiki Seisakusho Prism Instrument Factory late in WWII.  This bayonet has a very good blued blade with only light wear.  The wood handles are in very good condition throughout with only light handling marks.  All other metal parts still retain most of the original bluing and are in very good condition throughout.  The scabbard has a few dents from issued use during the War.  It retains most of its original bluing.  Known as the hourglass maker, this is a harder to find manufacturer in very good condition.
