I used coconut oil for mine. Started off with just 6 items, but then my hands were already oily so I figured I might as well do everything. Wiped off the excess with a paper towel.
Gasp! are those Myabi damascus blades? Nice. You have earned your second badge bit! You get an air badge for your first certified badge in each category (22 in all.) As you do more of the badge bits in a category you can earn more advanced badges.
Yes those are Miyabi! I got one of them new and the larger one secondhand. My favourite one though is the one to the left. Was handmade by someone from on the US (pig iron forge on Instagram) and handle made from reclaimed xylophone. The bread knife is a Japanese made one, so is the hinoki chopping board.
