How are the coatings done on the Alaskan Guide and the BPS coated 110's?

I've not read of anyone complaining about their coating peeling off. Instead, its the otherside, that they enjoyed them, they worked and wish Buck would bring it back. DM

I wouldn't imaging you would find anybody that would say it peeled off. After re-reading the explanation Chuck gave, it's like the "coating" is part of the blade and not a coating at all. I could imagine that this process is expensive and time consuming. It doesn't sound practical when churning out X thousands of knives daily.
 
This may help, CJ's post is #16. Hardness numbers may not appear in this discussion but good results abound. DM
It's not going to copy. I found a thread back in 3-18-1999 'Buck-Cote Testing' by amacks . Anyway theres some good stuff in it, espically a statement by longtime Buck employee Jeff Hubbard in post #13. I'll quote his statement: "Data in the real world beats lab data any day." DM

Thanks John. My wife fed me a good supper tonight, her green chile stew with deer meat, homemade bread and fresh baked chocolate chip cookies for dessert. After this my brain kicked in... :) DM
 
I think Jeff Hubbard has read more lab reports on knife testing at Buck than I have in the last 40yrs.. So, it's safe to say he may know something about the subject. DM

Well, that was almost five years ago and about five months before I even found this forum. Glad that it's been brought up again.

Yeah same with me Dave, hard to imagine you being a newbie, what is it....about 13,500 Buck knives ago? :p

Thanks for the thread DM and jb, just read it, very interesting.
 
The problem with the BPS and AG TDLC coated blades is that they are double bevel sharpened after the coating is applied. There is no hard coating on the micro edge. The Buckcote blades by contrast were single bevel (chisel) sharpened after the coating was applied which exposed the hard coating on the micro edge. Since the working edge was single bevel, it was twice as acute as a double bevel (inherently twice as sharp). Now combine a 92 HRC (hardness Rockwell C) micro edge with a 15 degree working angle, and you have a long lasting razor edge.
 
The Bass Pro coating IS Buck's coating of today. The Buckcote of 13yrs. ago will not be brought back as other customers complained about it. That they couldn't sharpen it and had to send it to Buck. Still, it seems many folks here could sharpen it and got good results. So, this is what we have today.DM
 
well if on one minds I will put my 2 centvos in on this
the 560 had to diff coatings on it one was thicker and would ware off ..
the other was like the Ti coating thin and much more durable

I have used a Ti coated blade and it stayed sharp a long time I like it
but have heard reports of brittleness and minor chipping
the Zirconium coating I have not tried but would love to

vaper depositing is some thing they use on plumbing fixtures to make the brass look!
real brass in bath fixtures is rare and expensive..

gosh I sure wish CJ and Hubbard would post like they used to.. :(

a question I have- is that razor blades are chemically sharpened by many brands
and is this some thing that could be done on a knife edge?
 
"the 560 had to diff coatings on it one was thicker and would ware off .."

That would probably be the black powder coated blades used in some. The same blades they recently used in some buildouts.
