I just got my 804 today and noticed upon inspection the end of the blade tang looks wonky. Uneven. Almost deformed. If this matches everyone else's then I will say that is what it is. If not, then back it goes.

I can't post pics in thread but check out link, double tap pic for blow up of it and you can see what I mean. From side view whole face of tang does not touch lock bar and blade tang end looks like metal is missing.

Lock is good but I can see where the blade has scraped and it only touches at the ends and nowhere in the middle. Yours is much better. I am sending it back to DLT. Huuuuuuge disappointment. With the tang not touching anywhere in the middle 50% of the tang, I don't trust the lock for hard use. Just me and maybe not an issue but this won't be in my collection.

Wow, didn't see it before but look at the pic showing the end of the tang and the right end is v-notched on both sides as well. Your pic shows that end flat cut and squared off how it should be. My knife is f*cked up. How did this ever get out the door?!

Send it back, I'm sure DLT will take care of you.

That's what I noticed 1st. What in the world happened to that blade?? DLT has top notch CS!
 
I received my 0804CF on Thursday, August 31st. My blade tang also has metal removed on the side that's in contact with the lock face which has the steel interface. So, the full blade is not in contact with the lock bar. Just the leading edge of the lock bar is. Lock up is pretty solid though. Looks to be by design.
 
Excellent service.....as usual....from DLT!!
Strong move Jordan!!

Thanks!!! You guys are great. I love buying from them when I can. Fastest shippers I have ever seen too. It will be in the mail today.
 
I am not sure if this is what is being discussed here but, in a properly built frame or liner lock the lockbar should only touch at the bottom of the tang.

Lockbars that fit flush against the entire tang surface tend to develop lock rock.

Interesting. Mind sharing the source, e.g., from an authority (manufacturers, knife designers)?

Won't blade play be more easily developed as the single point/line of contact can be more easily/quickly worn out? Checking my ti Mllie, Reate Horizon D, Hinderer, and all ZTs I see all with an area of contact rather than what you said.
 
According to Michael Walker, Emerson and even Strider this is how the lock is supposed to work. It creates three points of contact the pivot, the stop pin and the bottom of the tang. I will see if I can find the source hold on.

Yeah, that is also my understanding of how they should work.

This thread sort of adresses it. With a flat tang cut as opposed to a radiused it seems to be necessary for proper lockup. I will keep looking. There was a really good article Emerson posted with diagrams and everything.

However, Striders and Emersons do develop lockrock overtime in certain cases though
 
Triangles are strong and I have always understood that this is why they only contact at that one point on the tang's ramp. It is usually at the end of the ramp like that to form a more ideal triangle.
 
That's by design. It let's the detent ride over that spot smoothly.
