Late reply but those last two are Ko-Wakizashis, which are shorter katanas worn at the hip, behind the back, with the "Ko-" annotation meaning that they're shorter than an average wakizashi, being closer in size to a Tanto. Wakizashis were often worn with a katana to distinguish the wearer as a samurai.
When worn together, a katana and wakizashi are known as Daisho, literal translation is "Big-Little"
Thank you! Just thought I'de make my parfait look pretty by cutting the strawberries into 1/4s and arranging them like spears, then doing something similar with some raspberries. Topped with some homemade granola I made by adding quick [not instant] oats to some melted butter, honey and brown sugar, putting it flat on a baking sheet and baking it until it browned.
