The knives in 1095 are marked "CS".
If you recently purchase a knife stamped with "CV" it was "new old stock".
No. They switched.
They likely switched to 1095 as a cost savings. 1095 is commonly available. The CV steel was made specifically for them. That means they had to buy an entire heat of CV every time it was made for them. That's a couple of tons of steel, which they then had to carry that as inventory until they used it up. Carrying large amounts of inventory is frowned upon by the bean counters. It ties up capital you could be using for something else. By switching to a commonly available alloy, they are able to buy smaller quantities instead of needing to buy an entire heat. So overall it's cheaper for them, even if the per pound cost is the same. (M&P engineers are trained to think of such issues. It's a common issue for us.)
CV steel is finer grained than 1095 because of the vanadium. The chomium is added to give a more uniform heat treat in thick pieces.
