handy sponge / sponge

When using sponge cleaning knifes, we sometimes hurt ourselves because of carelessness.
So we open a chink on the sponge, and make this product as the shape of “V”.
Furthermore, we put the vegetable sponge inside the chink.
This material is harder to be cut, so that you won’t be hurt easily.
The product can stand by the V-shaped form, then it will be dry more quickly.
It observably reduce the chance to be moldy.
