Wood Eggplant knife?

[DanM]

My mother just returned from a visit to her sister in Israel. According to my aunt, eggplant turns black when cut with a steel knife ( I have not seen this, but I will roll with it). In Israel, they sell wood knives that look like cleavers to slice eggplants. This is apparently a fairly popular item. Has anyone heard of this before? Is there any truth to it?

Thanks!

Carbon steel knives will discolor eggplant. I always used a stainless steel but more recently a ceramic blade to avoid this.

Carbon steel will also cause lettuce to discolor along the cut edges.

My wifes mother, a Romanian, uses such a wood knife for preparing a roasted eggplant spread.
