Nice Bucks!!! Sorry the box end doesn't really help me with anything! I thought the ionfusion knives always had an X1 in the model number. (or something along those lines) Maybe Joe Houser will be along to help! I know the buckcote/ionfusions weren't made all that long. I don't think most people could wrap their mind around the one sided chisel grind sharpening. I like mine, but I only have an Ionfusion 110 and a buckcote Protege. Buck originally called them Buckcote, but changed after a year or 2 maybe? because its not really a "coating" it is ZIrconium Nitride atoms fused to the blade. You have the more common of the Crosslocks in my opinion. There werent many made with different colors in that model. (Buck did offer Gold, Champagne, Grey, Light Gold, even purple colored blades on other models) Buck only put the ionfusion blades on a handful of models though. (180, 110, 191, 192, 119, protege are all that come to mind right now.) The only drawback I could ever find is from the grind, they are not quite as durable during hard use. The edge tends to "roll" if cutting tough material. With that said though, they do stay sharp for long periods of time, Buck claimed up to 8X longer than their Edge2000 knives. Cutting cardboard, carpeting etc. in my experience- the material being cut actually removes the 420HC blade (think microscopic) under the ionfusion leaving the Zirconium Nitride on the cutting edge. I used an older one I had to clean waterfowl, and the blade dinged rather easily cutting through small bones etc. I loved using mine for rabbits and such, but stay away from bone! It also works great for skinning, but you have to be careful, thay are sharp!!
Did you remove the stickers from your blade? What is stamped on the side of your liner lock?
Just going back into Bucks catalogs, the Crosslock was first in the 1995 catalog.
Buckcote Crosslocks were in the 1997 catalogs,
Ionfusion came out in 2000
and by 2002 Ionfusion was gone already...
I hope I helped!!!!!!!!!
