I have been looking at some of the knives Buck offers more specific titanium. I can see the advantage of this for handles but what would you say are the pros and cons of a titanium coated 440 stainless blade?
 
Azis,
The blades that we used to produce with the titanium nitride "coating" were 420hc. If you are refering to the current ones, they are the same steel but the diference is that the coating is mainly there for esthetics. We give these knives, such as the Alaskan guide series, a regular two sided edge which means there isnt any titanium on the cutting edge.
The old Ion Fusion blades had a one sided edge which was done so that the titanium would actually be doing the cutting.
I hope this makes sense. As I re-read it, it does not make sense to me! :rolleyes:
 
So the Ion Fusion knives were chisel ground, with the coating covering the blade face with no edge bevel?
 
yes it does makes sense, so do these coated blade wear better , or maybe I am not getting the advantage of doing this.
 
Hello Vivi,
I think I am following you but to make sure, I'll try to explain it better than I did last time.
After a standard blade gets its final hollowgrind, we normally grind a 26 to 32 degree (included) edge on it. We do a few passes to each side to get a bevel on both sides, roughly 13 to 16 degrees per side.
On the Ion Fusion blades, the blades get the titanium coating treatment after hollowgrind and then we grind an edge of about 26 to 32 degrees although this edge is all on one side. If you look at the blade on one side, you see the thin strip of silver exposed metal. Looking at it from the other side all you see, all the way down, is the color of the titanium.
If I knew how to post pictures this would be so much easier. A picture really is worth a thousand words! :)
I hope this helps.
 
Azis,
The Ion fusion, one sided blades do wear better.
The ones we do today should wear the same as an uncoated blade, they just look better doing it.
 
Thanks Joe, I understand what you're explaining; we're thinking the same thing. I didn't know the normal Buck angles were ground that thin though. On my 110 they felt more obtuse, but it might of been one of the older ones without the new edge geometry you feature. I reprofiled it flat to the stone and it cut extremely well. Whenever I get another 100 I'll do the same thing.
