ACUTO 440 Stainless Steel

The ACUTO440 was import from Aichi Steel Group.  Also made as highvalue knife material.  Acuto440 is a modified 440C alloy, with a little more chromium andsome vanadium.  It will probably hold an edge longer than 440C, and should be plentytough, not that's an issue in a gentleman's folder like the Ripple.
