Don't know if it's exactly the same, but the 1415 was a pretty cool knife. If I remember correctly, they've been discontinued for about 6 years, or so. Does yours have the grooved half-circle on the back of the blade, for opening? or is yours the Hawks-bill blade?
Made in Japan, IIRC, and they all were good quality. I still have the Titanium-handled Hawks-bill.
