Corduroy,
The were supposed to be 0170-6, but like most latter produced BJ's that were marketed as 0170-6, they were actually 1095.
The head QC guy at BJ, Lee, lost 3 fingers polishing a Vorpal because there was no way for them to make an adequate jig to hold the blade and do their convex magic.
A very wicked knife. I concur on the handle.
