If the price is low, people will not like to counterattack and will not give a rating, so take care of the nuances. ￣￣￣￣￣￣￣￣￣￣￣￣￣￣￣￣￣￣￣￣￣￣ Oiri_Contact Email: [email protected] ▼Instagram   / oiri_kitchen   ￣￣￣￣￣￣￣￣￣￣￣￣￣￣￣￣￣￣￣￣￣￣ ▼ I would be happy if you could subscribe to the channel!    / @oiri_kitchen   ▼Related video [Knife questions] Troubleshooting | Theory    • 【包丁の疑問】お悩み解決｜理論   [Infiltration plan] I went to ◯◯!    • 潜入おいり【◯◯へ行ってみた】   #Natural whetstone#Whetstone pattern#Narutaki #Oiri kitchen #oirikitchen #Knife sharpness #Knife commentary #Knife basic knowledge #Knife trivia#leather
