Yes, I've used it on leather knife sheaths (ones that are finished smooth, not course natural leathers), wood, pearl, all different kinds of plastics and of course metal, etc.
I will say though, it's not so good on very porous materials. If in doubt test it on a tiny area that isn't easy to see.
And, I've found it will clean away any leftover factory polishing compounds. Many Of my Buck fixed blades would come looking beautiful and shiny. I would use RenWax (as it is often called) on the handles and a good deal of black polishing compound would come off in my rag! Making the knife look even better and shinier! (I will say SAKs are very clean and compound free!😇)
