I doubt anyone can tell me much about this one, but my grandson just aquired it and wanted to know if any info was available. The steel is quite hard; he stoned the blade for five hours before he got a fair edge on it. The metal-to-metal and metal-to-wood fit is very good, and the grain of the wood on the handles is quite good looking. There is not one mark or lettering of any kind anywhere on this one. Anyone? Anyone?
