Is a paper-knife recommended as a gift?

Many paper knives are particular about their shape and decoration, making them ideal as gifts. However, there are some points to be aware of when giving a knife as a gift.

There is an idea that it is unlucky to give a knife as a gift in some parts of Japan. This is because it has the meaning of “cutting the edges”. Therefore, it is safe to avoid it as a wedding gift. Of course, if the bride and groom want it, please give it as a gift.


The meaning that can be put into a knife is not all bad.


Paper knives are recommended as gifts other than marriage!

Cutlery gifts are not suitable for wedding gifts because they lead to “marriage cutting”. On the other hand, in Shichigosan, cutlery is used for blessings such as guardian swords for boys and kaiken for bride costumes. This is because it contains the wishes of “cutting off disasters” and “opening up the future.”


Therefore, it is recommended as a gift for relatives and acquaintances, a celebration of going on to school/promotion, a celebration of new construction/opening, a celebration of employment, a celebration of moving/starting a new life, a Christmas present, etc.
