Funny thing in the lock on a Buck/Mayo

I'm sure this has been addressed before, but I just got a buck/mayo 172 and I noticed a little sliver of metal in between the framelock bar and the back scale. it's right where the little cutout is that lets it bend. Does anyone know what this is? Is it just a hunk of scrap metal?

Thanks

Here are some pictures as best I can do. What you're looking for is a little sliver of shiny metal right in the gap between the lock bar and the rest of the scale. I've looked at it with a loupe and there's a little bit of ti from the lock bar that sticks out to touch it. It also appears that this little sliver was there when they bead-blasted the scales, as it has that finish on the top of it.

Mine has it. I think it helps keep the frame lock evenly spaced, and from rubbing. A piece of paper will not slide through that area on mine.
 
So is it meant to be there or a defect? How could mine and Scott's have it but not Buckaholic's?
 
Scoot...
Are you talking about that lighter metal in the third pic of NFMee's?
I don't have that on mine...looked under a glass and nada.
Do you have a pic Scott so I can be certain at what I am looking for.
Although, suffice to say, that my Mayo TNT does not have anything that looks abnormal.

If it is a "feature", maybe mine doesn't have it since I've had mine for many moons now and it down-rev.

Interesting that there's no date stamp on my TNT but there is on my Waimea and Kaala.
Do newer TNT's have date stamps?
 
I agree with the Goose! I carry my TNT every day and I'm looking at it as we type. All I see is daylight when I look down between the lockbar and the rest of the scale. :o
 
Here's a pic with a piece of paper against it. I also de-horned the frame and opened up the thumb depression on the frame, I really like it now.
 
Yeah that looks like the same thing as mine. I wonder if it's a thing they added to stabilize the lock bar?

PS love the de-horned top of the frame.
 
From the pics, Scott and NFMee, your knives don't seem to have the same feature. While ya both have that metal there, they don't look indentical.

I'm thinking it is residual from the mfg process.

Here is mine:

I agree with Goose. Those bits of metal sure look like grinding burrs.
 
Ya' know it probably is a burr left over from the manufacturing process, but it doesn't snag my fingers so I'm not too worried about that defect. There's just too many good features to enjoy :cool:

Yup, I would be happy with a Mayo, burr or no burr. :thumbup:
 
:cool:...Looks like misaligned tooling to me...Most likely a sheared punch in the prog die...( Before I got into "butts"...:eek:... I was a Quality and Mechanical Engineer in a fine blanking firm... )...Seen that condition before...:D
 
So it sounds like not necessarily a defect, but still a manufacturing error. I wonder if I should send it in to have them clean it up?
 
I would only send it back if it REALLY bugs ya and ya can live w/o your Mayo for a few weeks.
Like Scoot said...I think it is minor in the overall greatness of the knife.

Scott..I know others have done it...but while I have wondered, I have never asked...
Why get rid of the horn?

I saw what Gary Graley had done to his and it made sense, those "horns" jabbed my thumb when alot of pressure is applied when cutting. Now it's a nice smooth transition from the frame onto the spine of the blade; no problems for my thumb, since sometimes I do cut more than just envelopes;):D
