I need your opinion on how durable the spring on the ZT0301/2 is. How long do you think before it loses its springiness ? Anyone ?

Not a big fan of auto / assisted opening, so this whole springing thing is new for me.
 
I haven't fired my 301 that much at allbut I've got thousands of openings on a leek and chive and they've had no problems and the 301 is much more heavy duty.
 
It will probably last longer than you do.:D But if the spring did wear out, Kershaw/ZT will send you a replacement for free.:thumbup:
 
i use mine daily at work. still opens with authority after a year of more than moderate use. if the spring breaks, it's pretty easy to replace.
 
Hmm, I just got a Kershaw 1670 blk, after 3 days of opening it is still good, however, I cut the crap out of my thumb while closing it. Kershaw (ZT) has a great repair policy.

you can remove the spring i think if you dont like it. I also think if it was to break, the knife would still continue to work!?!
 
The torsion bar can be easil replaced if broken, and ZT will send replacements free of charge. I have carried mine daily for about a year and a half with no issues. It stills opens as it did frsh out of the box. Just keep it clean ond lubed.
 
not to mention the torsion bar inside is pretty husky. Its up to more punishment that you will probably ever deal it.
 
I've broken several bars on various kershaws, mostly from playing with them too much. As everyone already stated, you can replace them or send the knife back to kai, they have excellent service. Also, the knife will work fine even if you do break the torsion bar, some people realize they like their kershaws better as a manual when this happens.
 
I've opened mine at least a zillion times and it still fires true. I take it apart to clean periodically, and militec'd it when I first got it. It was a user when I picked it up so who knows how many other openings it had been through.

This is the only problem I've had with it. After tweaking a bit more it seemed to get comfortable. I haven't replaced that washer. Disregard the insinuation that I don't take care of my knives, I'd only had it a week at that point. :)
 
I drive buy Kershaw several days each week. You want to know how well that bunch stands behind their work. I'll tell you. They are so fastidious about their products that I don't dare slow down with the window open for fear that one of them will grab up my 300 series to make certain that all is in order with it, clean and sharpen it before I can drive past.

My thumb has calluses from working this knife while the knife itself remains a marvel/high water mark of folding cutlery by never failing to please and amaze me.

You can see a pic of the spring in this thread:

It is quite strong...and as others have intimated....fires now just like it did a year or so ago when I first got it.

The thumbstud prevents the blade from continuing it's arc while opening. If you have a leek or a chive, it's the same design only all growed up.

When opened the blade cannot continue rotating past that point, and the framelock prevents it from rotating back to closed.

edit:
From Daniel Koster's thread above:

Notice the thumbstud.
 
The thumbstud swings around and makes contact with the cutout in the front of the handle slabs...acts as a stop pin.



edit: just saw the above - great post. :thumbup:
 
no i mean how does the thumbstud hold in place? what is holding IT? The just slide into the blade?
 
if its similar to my kersahw mini cyclone, they can be pushed out, but considerable force is required. I do wish they had studs like BM that can be easily taken out with a torx screw for cleanings and such.
