Can't speak to the Decater, but the Castleford, which is a cheap Chinese knock off, it clearly inferior and quality control is pretty hit or miss. The Castleford blades are thinner, and they sometimes have the burr left on them. The plastic is rigid and cheap, where as the plastic handles on the Pipnet are very high quality with surprising tensile strength. I have other reamers, including a set of Danish made steel reamers that fit chamber sizes not covered by the Pipnet. It's good to have the correct tool for the job, though I rarely have to ream anymore.
