Liner lock longevity

I've used Buck/Case knives all my life and various other lockbacks/slipjoints. I've never wore one out. I've recently got and fell in love with a Buck Alpha Dorado and a Buck/mayo Wiamea. I've had some concerns about the liner lock lasting and it looks like there might be a problem with that.

When I first got them ,both of the liner lock knives the lock engaged just perfect. Both knives became my favorites of all my collection for use. I've had them about three months of pretty heavy use on a farm and opening letters and boxes. A check shows that the Buck Wiamea has used approximatly half the wear that was left in the lock when I got it. ie: As in its used up half the gap between the lock and other opposite liner that there was when it was new.

The Alpha Dorado has used up about 1/3 of the distance in just two months. While I love the ability to open and close the knife rapidy and with only one hand these two knives are on a pace to hit the opposite liner in less than a year at this rate. Are liner locks not ment to be used frequently? Will the wear rate slow down as it engages more of the blade bevel? Its got to the point I hate to flick open the knife as I feel there are only so many openings left in the lock. Time to put my Buck Prince back in my pocket (a great knife) and put the Dorado/Wiamea in the drawer I guess......:confused:
 
You have probably been opening your knives to rapidly, if you open them with a strong force the blade can actually bend the liner a little, and little by little your liner will not have much blade to meet up with. Thats not a terrible thing only because Buck will replace it if it does not function anymore.
 
I believe the rate will slow once some initial wear has occurred. Keep an eye on them though I had knives that wore literally all the way across in about 50 openings.
 
I don't know about buck but I have a few knives, some more than 8 years old, that are liner locks that are still going strong. My mini-stryker has been opened literally hundreds if not a thousand times and while it has moved some I still have complete trust in it.
 
I've got a Kershaw whilrwind that has been opened thousands of times and the liner lock still engages where it did when it was new. The whirlwind is an assisted opening knife so it always opens pretty hard.
 
I have a couple of Bucks but I don't EDC them. I do know that, compared to my Emersons and Chris Reeves, the liner locks do look flimsy in comparison.

The real question is the quality of Buck's support. Will they refurbish recent purchases if the liner goes bad?

When comparing a $40 Alpha Dorado to a $300-$400 Chris Reeve I would hope the Reeve is much more rugged.

If it should wear out, Buck will absolutely repair or replace it "forever".
