pearl is such a pre-90s thing, haha. just my opinion, but i think the modern knife world moved away from pearl and other natural materials (wood, bone, etc.) because they can warp if the environment changes (temperature, humidity, etc.) and they are more costly to manufacture, compared to say, FRN or G-10. I never owned a mother of pearl knife, but I do want one in my collection, maybe in a traditional slip joint.
