Sounds obsurd, I know. But I have two reasons for asking how to remove the Titanium Nitride coating on a knife.

Reason one: In a another thread, I've been fishing for suggestions based on a certain criteria. One of the suggestions I got really has my attention. Trouble is, it only comes with a TiNi coating. I very much prefer a satin finish.

Reason Two: I have a BM 9053SBT that has seen better days. I believe I could dramatically increase the asthetics of this knife if I could completly strip the TiNi coating that is scratched and chipped.

Thanks all.
 
Try a soak in hydrogen peroxide. When bodycote had a representative at blade a couple years ago he mentioned that they had a problem with people getting Hydrogn Peroxide on gold TiN coated bathroom fixtures, which stripped the coating.

*edit* You say scratched and chipped... and that the last part of the model name is "BT". This leads me to believe that it's not a nitride coating, but benchmades old teflon based coating, which hydrogen peroxide won't touch at all, in fact I can't think of anything other than elbow grease that will, then you have to deal with the possibly very rough surface under the coating.
 
Even though it may get rid of the TiNi coating I would think twice about dunking a blade steel into a strong oxidizer. I would think that the blade will go together with the coating.
 
Thanks for the reply, Yoda. The knife in "Reason One" is actually listed as having a Titanium/Nitride coating. It's a Kershaw. The BM in "Reason Two" does have the BT2 Coating.

From the BM Web Site:
"BT2™ BLADE COATING- Our own proprietary blade coating is a polymer offering excellent corrosion resistance, which exceeds the ASTM-117 specification for saltwater corrosion resistance. The black surface will scratch and scuff with use, but its anti-corrosion properties will continue to protect the steel. Its high lubricity also improves knife function. "

Looks like I'm stuck with the crappy looking BM. Nice to know that it's still "protected", though.

As for the Kershaw, I will investigate the H2O2 further. The knife is inexpensive enough that I would not get too torn up about ruining it.
 
Call Benchmade's Customer Service tomorrow, and ask them about replacing the blade. It should not cost any more than that.

Thanks for the tip, Kohai. Maybe they still have a few satin PEs lying around. I'm not Really too keen on any coated blades.

Which brings me to this follow up... I found out about the CK&T Random Leek with S30V steel. Once again, the blade is coated. Why does everyone have to paint the good steel? It's like building a piece of furnature out of ebony and then painting it white!

The Random Leek has a boron finish. Any hope of removing THAT finish with out a 80 grit bench grinder?
