Ray Iles RI021 2" (50mm) plane iron fits the Stanley No.4 & No.5 (Bailey pattern or Bedrock pattern), Record No.4 & No.5, Quangsheng No.4 & No.5 and equivalents
This high quality 2 - 2.5mm thin iron, made from O1 carbon steel hardened to RC59-61, is designed as a drop in replacement for valuable old tools where alteration of the mouth may adversely affect their value. Installing a Quangsheng or Clifton cap iron with this blade will give 80-90% of the benefit that would be achieved with a thicker iron.
