April thinks I have a compulsion for Japanese tools. I think she may be on to something, but I’ve got a pretty good excuse. Very generally speaking, Japanese tools are often well designed and manufactured, and the plaster tools are not unlike the acclaimed kitchen knives and woodworking tools. Japanese trowels are made with a careful level of attention in an incredible assortment of sizes and shapes, and different types of steel depending on the purpose.

And usually pretty cheaply made.
