Delica 4 issue

Hi Dano1987,
Just a quick follow up to this issue. Sal and I spoke and he tested your Delica himself. He could not get it to defeat. We're not sure if there's something with your technique or what is causing it to fail for you, but we still can't get it to fail. Regardless though Charlynn is processing a replacement for you so you should be good to go.

Excellent CS from Kristi and Spyderco
 
I have 2 Delicas coming in the mail tomorrow.

Should I slam the back of the knives against a table to check for lock bar flaws? Maybe just drop them a bunch of times on the blade? How can I be sure they won't fail?

Please advise...

I usually check them by putting the handle in a vise and smacking the spine of the blade with a sledge hammer. For some reason, all my folders have been defective :(

Well crap - That's that then. I'm just going to return them.
 
I would not test any knife with a spine wack. I really though all that nonsense was over. To me when the blade is open and there is no play and I can't close it like I am closing a slip joint the lock is good to go. IMO a lock does not really need to be super strong to prevent accidental closing. Many locking knives are also designed so as your grip on the knife backs up and reinforces the lock. This is even more so in frame locks.
All that said in all the years I used slip joints I have only had one knife accidentally close on me. It was a Case slip joint using it to cut a very thick large box.
Way to go Spyderco for making this right.
 
I don't normally stab straight down or at an angle that if the lock failed I would get cut.

Because of the way it's designed, lockback is less prone to jarring/shocking force as opposed to the liner lock. Check STR subforum, he had a sticky on how to safely test a lock with minimum wear/damage.
 
^ What does that have to do with a Delica??


....I don't even know why I'm posting in this thread and keep bumping it up, sorry.

It has to do with folding knives potential for lock failure and why I prefer fixed to folders. As his video demonstrated lock failure. Simply put I was commenting that folders have so many more fail points than fixed blades....hence I like fixed blades because fewer fail points on the lock. His complaint was lock failure, fixed blades don't fold on your fingers...I like my fingers and the improved chances fixed blades offer that they won't fold when least expected. I can't possibly be the only guy that prefers fixed blades because of incidences like the OP describes.

The thread is not about fixed vs folder!!! This is not a preference thread. It's about an issue the OP had with his Delica and he now has a resolution. There are plenty of other threads discussing the merits of fixed blades.
