Humpty,
Hold on big fellow!
I don't think we have a ruined knife,..maybe just a little lubricant overload. The mighty Sebenza is a very tightly fitted knife, and really doesn't hqave 'room' in the pivot area for that much 'stuff'. A couple of questions first...
Did you disassemble the knife to apply the lubricants? If not, you really can't get Smooth-Cote, BP2000, or Hi-Slip into where it needs to be on this knife.
If you did disassemble the 'Benza, are you sure you reassembled it correctly[and adjusted], this can have a MAJOR impact on how the blade rotates.
I would start by flushing out what you have done, experience tells me that break cleaner or 'gun scrubber'[in the spray can from BIRCHWOOD CASEY] reallly dissolves the SENTRY SOLUTIONS family or products on contact. I mean instantly! So clean up what you 've got. Then make sure you have got the knife adjusted the way you want. The Sebenza, with itspolished internal bushing and its bronze washers shouldn't need alot of lub., but if I wanted mine REALLY smooth, I would disassemble the Knife, clean it really good, apply Smooth-Cote to just the pivot area and washers.Let dry[help it along with hair dryer], then , with a q-tip, I would rug a little BP2000 powder into the pivot area and washers. Just a very small amount will do. THe treated area will take a metallic, silver-grey sheen. Re-assemle the knife, and re-adjust. I would NOT use Hi-slip grease in this knife. The Smooth-Cote and BP2000 are DRY lubricants, and will not attract dirt or pocket lint, but the grease can. It also can cause a tolerance problem in your finely fitted[read that tightley fitted] Sebenza. You should not need Hi-Slip Grease for this application.
And be sure to keep the locking surfaces clean and lubricant free. These surfaces need to be lubricant free to work best.
Hope this helps. I've had great experience with the Sentry Products,...just be sure to use the ones you need, and remember, a little goes a LOOOONG way with this stuff. Less is more.
PS, you may find that with this High quality knife, a little Sentry Tuf-Glide is all you need in the pivot area, and you don't have to disassemble the knife.
