MarcH, I agree that this is not a deal breaker issue. I only became aware of it due to the fact that my jaws were sticking closed which required disassembly. This was one of the issues I found upon taking everything apart…

I wanted to follow up on my progress with this knife. I received diamond lapping films from Nanolap, 6/3/1/0.5/0.1 micron. These did the trick! Much sharper thank before!! I did have the same issues with the 0.5/0.1 micron films with larger scratches showing up. I will proceed with the DLF to 1 micron, stop there and move to strops!
I really enjoy the chosera stones and will continue to use them where applicable.
Thanks for all of the input!
Finally was able to revisit the Spyderco Manix 2 S110V blade. After receiving the 800/1000 chosera stones, I tried to back up and see what they would do ( I finished with the 10K chosera last go round) while keeping the same 18 deg angle. I was not successful.
From there, I went back to the 1500 diamond confirming the scratches were consistent from shoulder to apex and verifying a burr before moving on.
From here, my progression was 800/1000/2000/3000/5000/10,000 chosera. Scrubbing first then edge leading, per forum recommendation, with very light pressure until each grit had scratch uniformity. Finally, light stropping at 16 deg with both 1 micron and 0.5 micron leather strops.
Again, this blade is sharp but not where near where I would expect it to be. I do not believe it is my technique as I followed this with a Shun VG10 blade using both diamond and chosera to 10k and it is screaming sharp! I know the S110V steel is supposed to be difficult to sharpen but I am at a loss… I have ordered a set of DLF from 6 to 0.1 micron and will try them when they arrive. I can’t imagine that the DLF will solve my issue but don’t know what else to try.
After reading this post, I decided to pull out my much neglected/ignored ceramics. I have both micro and super fine sets. I decided a while ago to not even try to use them given the results I was getting.
Today, I took them out and spend 30-40 minutes per grit lapping them together while watching TV, added water and cleaning them regularly during the process. I did notice that the dust did start heavy and end very light. I also noticed that the shine which the stone surface had when I started is now gone. All 4 grits are now dull in appearance.
I took a test knife and used this progression, Diamond 400/600/800/1000/1500; Ceramic 1200/1600/1.4/0.6. I was not trying to get a perfect mirror and did not pay attention to completely working out the prior scratch pattern with the next grit.
Let me first say that the feel of these stones completely changed, for the better. They went from smooth but able to feel and hear the grit to feeling completely smooth, hearing/feeling next to nothing, like glass on glass. The haze that the 1.4 produced before lapping is gone. Had I spent the time to examine and completely remove prior scratches, this would have been as good if not my best work yet! The edge is hair splitting! (I tested it)
I now need to figure where they really fit into my progression. I am very encouraged!!
cbwx34, your demonstration is exactly what I was envisioning to prove this concept. Your perspective of view (photo) shows that the angle relative to the blade does not change. YES, the angle in the plane of the arm relative to to the work surface does change and I believe this is where he is confused.
snecx, your glass example is again an excellent demonstration of this angle remaining unchanged. How can either of these be confusing or discredited?? Well done guys!

I just sharpened a ZT450 through the 10,000 chosera stones. Upon completion, I disassembled the vice and found no water or slurry on the cam, or inside the vice for that matter. I did not do anything different intentionally from the last time I used the choseras. Unsure how I ended up with rust on the cam before.
That said, I did warm the cam up and apply Frog Lube and let it cool. Hopefully that prevents rust from showing its head again. I will also disassemble the vice following use of water stones every time.
