There's an expression: If it ain't broke, don't fix it.
Which, of course, means that things that can and should be done ahead of time get ignored, water pumps fail on a vacation when you knew the car had 135,000 miles, etc. There is a thing called preventative maintenance, too. And if you want to compare notes with professionally anal people about that, talk to the ones who travel about in flying machines. That brings up another expression: Failure is not an option.
But we're just talking about a knife, not life and death. My SnG is over five years old, looks it, a user, locks up just fine, cuts open clamshell packaging even today - and it just gets touched up on crock sticks. Strider makes their knives to a different standard, you might call it military grade - premium materials, strong design, capable of taking abuse that would cause other knives to fail, not much on looks. Military grade today isn't about knights in shining armor and dressy ornamentation, it's about functioning in harsh conditions during years of service. Kinda why any comparison with the Sebenza has always been apples and oranges. Neither designer ever meant them to be direct competition to the other's purposes, they just have overlapping customer demographics.
One of the those demo's is the ability to spend some money in an effort to maximize the knife as being state of the art. Again, neither does that, they are really a snapshot of what the makers saw ten years ago. Knives are still progressing, and the leading edge is now starting to move away from some of the features they share - like those knives with a carbide insert in the lock bar. And the problem there is the lock tang is now the softer material, so it's still going to wear and loosen up.
The average knife in daily use was expected to last less than 36 months during the 1930's, and now, I suspect knives with S30V and titanium lockbars will be passed down to the next generation. They are that good. I wouldn't worry too much about getting things carbidized, when the next better way of doing it is likely just a few years in the future. Buy it now, use it, don't worry about it, and if it should happen, then deal with it.
Cause, if it ain't broke, don't fix it.
