So I am wanting to remake a blade for a customer. It a blade made to cut rubber. On the blade it says RBSS. The SS stands for Stainless but im not sure what the RB Stands for. The customer says he thinks its just Toolgrade stainless.

So anyways does anyone know what this RBSS is. and know where i can get some.

Also does anyone know where i can get stainless in these dimensions.

0.031" thick X 2" Wide X 12" Long

Thanks Eric,
