I rusted the liners on my Police 3 in VG10, but that took me 3-4 years of year round carry, and the rust was about 30% of what happened with the Police 4. Don't recall any rust on the blade, backspacer or lock bar on the P3.
I knew the blade on the P4 would require more attention, but I did not expect the same of the liners.
Vivi, looking at your pics of the Police 4 (K 390): Sure, a lot of rust on the liners, not doubt.
But, and correct me if I am wrong: Does that really matter speaking strictly functional?
And how many years would you have to carry the knife without ever cleaning off the rust till it WOULD get a real problem functionwise?
These are honest questions, since I personally never had any serious rust problems whatsoever on my folders, despite carrying them a lot in sweaty pockets and sometimes over days in wet conditions (mostly VG10 though). So I have no real experience here.
Might be, that your enviroment (the air) is a lot more salty than where I live (next salt water around 200 miles away I guess and winds coming from there shielded off by hight mountains)
It could go a while and still be functional, no doubt. Some of my concerns would be:
- Gritty action which would get worse over time, and eventually rust particles would cause uneven wear between the metal parts.
- I would not be comfortable using the knife around food.
- The knife will eventually become very difficult to open and close.
- The smell gets pretty bad after a while.
- The rust would eventually spread to the blade more, and eventually the edge, forcing more frequent maintenance.
- I've seen locks fail due to rust (But not a Spyderco lockback)
At this stage its preventative maintenance, but eventually, left neglected, it would alter the functionality of the knife.
Both my Police folders are still fully taken down. I haven't decided what I'm going to try coating the liners with after I sand out the rust.
