To provide a kitchen knife for honey that can prevent honey from flowing out under the nest by cutting out the nest from the Japanese honeycomb box and preventing it from being dropped in the nest.SOLUTION: This is a quadrangular kitchen knife to be used for cutting the nest in the nest box when honey is collected from the multi-type nest boxes of the Japanese beeswax, and the blade width of the knife and the width of the case 1 are larger than the width of the nest box It is long and is characterized by adding a blade 2 to one side of the four sides of a kitchen knife, and raising the edges of three sides other than the side. Simultaneously with the cutting of the nest, the nest rides on the trunk of the box kitchen knife, instantly closing the cut face of the cut off part, and the barrel becomes a gap from the lower part of the nest, and prevents the flow of nectar.BACKGROUND OF THE INVENTION【課題】日本みつ蜂の巣箱より巣を切り取り、採蜜する際に流出する蜜が巣内下方に落ちるのを防止できる採蜜用の箱包丁を提供する。【解決手段】日本みつ蜂の多重式巣箱から蜂蜜を採収する際に巣箱内の巣の切断に使用する四角形の包丁であって、包丁の刃渡り、および胴1の幅が巣箱の幅よりも長く、かつ包丁の四辺のうち一辺に刃2を付けて、以外の三辺の縁取りを高くしたことを特徴とする。巣の切断と同時に巣は箱包丁の胴に乗るため、切り離した部位の切断面を瞬時に塞ぎ胴が巣の下部との隔たりとなり、蜜の流落を防げる。【選択図】図1
