Bottom line is this......the Buck "Company Line" is that stamping weakens knife blades to a degree so serious that Buck is going to engraving rather than stamping on many of their knives.

Problem......I have never heard of a blade failing due to a stamp. Millions in use.....hello.

Buck does not answer questions about the issue.

Buck says they have done tests that prove their conclusion, but it's all strictly in-house and they will not share or submit the tests to neutral third parties for confirmation.

And, because I reserve faith as the assurance of things hoped for, the conviction of things not seen.....only for God, and not for men--I'm skeptical.

Therefore, until I see the apocalyptic failure of the millions of stamped knives in use, OR the Buck's release of their tests for verification by independent science--I regard Buck's claims as bogus and engraving as a method to save a few dollars.

Dave 110 (who admits to some bias toward Buck) said this:

(Note: Those of you who know Dave will notice that he wrote this in a highly unusual way........he wrote in normal prose rather than his usual encrypted jargon--that shows how upset he is about this issue.)

Here's Dave:

I speak from experience at a high end consumer product company and other past time activites
I have seen steel fail at ‘stamped’ locations so it is not a fabrication

Testing results of any kind are almost always confidential data as
it can give competition way to much insight..
we are privileged to be told any thing of Bucks testing and results
and it is foolish demand ‘raw data’ as proof..

There are but a fraction of knives that are not basic carbon or stainless
and we are told that it is the alloys are ‘more’ subject to this,
and not that the normal steels are not.
But expensive alloys are not the only steel that this stressing happens to
I am willing to bet it has happed to the 420 hc or 440c or 425hc also
and I am willing to bet others are also going to etch also for a better blade

As to weak stamp location failure- there are weaker points for a blade to fail at..
the beginning of the grind and the cut were the guards go are weaker then the solid stamp location
Every one I know has seen blades break at those points
I would say that is why you don’t see the failure at the stamp on finished knives
And that Bucks Quality control had keep us from seeing unique failure on theirs

i am not suprised that Buck has decided to go to etching alloys with their mark as
they always have done what ever is needed to make a pratical knife better

It is expensive to set up to put a stamp or mark of any kind on steel
So I feel that it is not a cost cutting device/move either way

As to the blades that Buck had with the stamp on the top edge –
I am willing to bet was hand applied for custom shop use and LE use
Very expensive to make a hand applied tooling stamp
And yes I would pay for extra hand operations on MY knives.

in short -
we dont see that failure as there are weaker locations for a knife to fail at
and we dont see the ones that fail at the factory from this
that we dont see it does not mean it is not a true condition
that Buck is takeing steps so that we will not see it is commendable

So, Dave110 admits there is no real-world practical evidence that knives are weakened by stamps.

He explains that by saying that "there are weaker locations for a knife to fail at."

I can't buy that. If knives always fail at weaker locations there would be no point in eliminating the stamp.

He also says:

that we don't see it does not mean it is not a true condition

That's like saying that because we don't see pink unicorns flying around, it doesn't mean they don't exist.

Sorry, Dave.....I have to SEE a pink unicorn before I believe they exist.

;)

He also says:

It is expensive to set up to put a stamp or mark of any kind on steel
So I feel that it is not a cost cutting device/move either way

Engraving is much easier and cheaper.....and can be done at any time, so it avoids the problems that occur when people forget to stamp blades (you can't stamp them at the END of the process, only the beginning).

All in all, I find Dave's arguments unpersuasive.

Still hoping for some serious answers by Buck that would support their position.
 
I for one think engraving is a poor choice for marking knives. For one, Buck has been in business for 50+ years and they are just now making the move to start engraving there blades. Does this mean that there is 50+ years of product destant to fail, because they were stamped. Secondly, engraving doesn't last as long as a stamped mark. This means that in 50 years when my grand children start their collection of Buck knives like Grandpa they will have no way of dating their knives, because the engraving has worn off. I think this is a bad decision and hope the Buck family reconsiders. If its a cost saving thing, I'll spend .50 cents more on a knife...
 
Regarding stamping 'premium' steels at high hardness (per the subject of the original thread, now closed), I found an interesting tidbit in another sub-forum here on BF. It occurred to me, all of Spyderco's knives I've seen (I have a lot of 'em) are laser etched, not stamped. Spyderco is well known for pushing the envelope, in terms of trying out new premium steels at high hardness. The increased hardness & wear resistance always comes at the expense of ductility and impact resistance, resulting in increased likelihood of cracking/breaking/chipping.

Watching the 'discussion' here in the Buck forum on the topic, I began to wonder if there's some specific reason Spyderco marks their blades the way they do, with a laser.

To quote Sal Glesser, Spyderco's founder, in a discussion regarding some of the benefits of laminating hard (premium) blades with a softer steel:

"Exotic steels can be very hard on tooling or require a laser (expensive). Laminating with a softer steel makes stamping feasible."

Here's the thread (Sal's quoted comment is in the 5th line of post #38):
http://www.bladeforums.com/forums/showthread.php/729813-Why-clad-VG-10-in-420?

Seems to me, Joe H. was communicating along similar lines, in his quoted comments about stamping Buck's premium blades. I really don't believe he's (or anyone else at Buck, 'company line' or not) is making this stuff up.

The danger of cracking a premium steel blade at high hardness, by smacking it with a stamp, punch, hammer, etc., is real. If they say they've had some cracked blades as a result, I can easily believe it. The fact we haven't 'seen' many of these cracked blades might just be due to the damage being seen at time of stamping, and broken blade disposed of immediately (QC actually doing what it's supposed to do). Whether Buck decides on laser engraving, etching, or some other means to mark their premium steel blades in lieu of stamping, I'm inclined to believe they have valid reasons for doing so.

This question came up for Buck almost 50 years ago with the first 110. Apparently, hand stamping caused some serious stress fractures. Although the blades were much thinner then, it isn't unreasonable to assume that stamping still creates stress in the now thicker blades. The solution then was to etch the blades. That was good and bad for collectors. If you can find an etched 1st Version 110, it's good. If the etching has worn off, it's not so good.

Also, there seems to be a bit of confusion in this discussion. Are we talking about engraving or etching? - Bertl
 
Obsessed with Edges.........Let's be clear, I never said Joe was making this stuff up. Joe is speaking for Buck and that's what Buck has to say. It's the company line.

He can't say anything else. That's their story and I wish they'd either give up on it or back it up with some evidence.

As to this Spyderco stuff.....I think steel is stamped BEFORE it's hardened. Maybe there's some confusion as to what your link is about.

But, that's interesting information. I'll check up on what this Glesser may have been talking about.

Thanks.

As for my 2 cents' worth, I was referring to either one (laser etching, or mechanical engraving) as alternatives to the old-style stamping (by impact). Can't speak for others in the 'discussion', such that it is. ;)

Seems to be mostly engraving, although apparently there has been some etching on blades, too.

Also, all the reading I've done on this indicates that the weakness caused by stamping (on good quality and competently heat-treated steel) is such that it would require more than human strength to break a blade at that "weak" point.

In other words, the alleged weak point is one of the strongest places on the knife.

Update:

I've been informed by a couple of people via e-mails that Glesser's post in that thread is referring to VG-10 blade blanks being laser cut from stock, and not being blanked(a.k.a. stamped). Nothing to do with engraved vs. stamped ricasso stamps.

The knifemakers forums seem to agree that stamping of maker's marks is best done on annealed blades and heat treat is done after that.
 
I personally think the new engraving is a poor choice as mentioned earlier, it will wear off to easy, I have one that is brand new and faint to begin with. I think the stamping buck did has some contribution to making it more desirable to collect, as you know what you have, vs a knife with no or worn markings, leaves you no proof of what it is. I would imagine the stamping also makes it easier to diferentiate from counterfiets.

I like the stamp (or something that will last equally as well)!

Laser etching is merely cute, while it lasts.
 
Further more if the issue is breaking during manufacturing, how many blades out of a thousand are affected?

If it is a matter of weakness once complete, than the knife was being used way outside the boundaries of what the warranty will cover.

Keep the STAMP (unless it can be engraved just as deep).
 
Here are two to compare.

I'm not going to debate the impact of it from the maker's position since I have no knowledge of that.

However, I far prefer a good stamp to laser/acid etching any day!
 
Well, the one bright spot in the whole issue (as far as I'm concerned) is that Joe said that they are looking into ways to use the stamp as in the past.

I believe they can do it and I sure hope they decide to do it, at least on the more traditional knives.

I couldn't care less how they mark the tacky plastic tacticals, but the older knives, quality build-outs, Limited Editions and customs merit more respect.

Buck has a proud history and cheap engraving instead of real stamps simply does not go well with that history.
 
Etched, stamped, or engraved, doesn't matter to me. If it helps Buck to retain a price point, in a poor American market, and stay competative in a world-wide market, I'm in favor of it...which-ever...what-ever. Blade stamps are fairly costly....and have a limited life-span, and with Buck dating symbols changing every year, it may come down to dollars & cents. Make a few knives...stamp the blades....have them break, either while stamping or afterward in use....then you'll know first-hand that Buck isn't BS-ing
 
It's obvious to all that breaking in use is not an issue......there is no real-world record of that being a problem.

If increased production costs due to breakage in the process of making the blade are the problem--engineers should be able to come up with a solution.

Permanently terminating a percentage of your oldest customers by using cheap engraved maker's marks is poor strategy, even if it saves a dollar or two on a fifty dollar knife. You may save on one end but you lose on the other if a lot of people don't WANT that knife. Better steels and offering new combinations of steel, handles and trim on Limited Editions and build-outs is a good strategy and proven popular. I'd pay the higher price without blinking.
 
Having said that, I should repeat that Buck has repeatedly insisted that this is not about saving money......but I think most of us realize that it IS about saving money.

I floated the topic among some knifemaker's......here's a few responses.

Every knife I've ever made has been stamped. Although I've never had a knife returned for a broken blade I have broken several test blades on purpose and never had one break near the stamp. I don't know maybe I've just been lucky.

In my not exactly humble opinion... For some reason known only to Buck, stamping is more costly. Their "story" about stamping and blade strength is a way to explain their cost effective decision to the knife buying public.

I agree with you

they have the volume to justify laser engraving
- It's probably faster and therefore cheaper,

with practically no maintenance especially compared to stamps which would wear and need more maintenance downtime.

and instant changeover to different logos or lines.

I think the true situation is obvious here and it's a bad decision that's creating a problem.

Does Buck care?
 
roflmao
i see you are still dipping
$hit from under the out house there rosy..
and selling it to a bunch of newbies now
and got them going to boot !
you are still good at that..
oh well
new name-same samples.. lol
jest be carefull you dont upset a mod
and get baned again!
omg-
jest hold that thought a moment...
is Joe a mod ?
yes i think so... last time i was here any ways...
OMG !
that means
Joe can ban you!
you should play chicken
back off makeing him up set and
word every post very carefully
AND say you are sorry and wont do it again
(like the last time a mod got on you about some thing)
or
do you like liveing over the edge?
 
I'm happy to report that all of my Web Specials arrived with great stamps. Hope they keep stamping.

One happy camper here!

:)
 
well BG i for one am glad you are happy with your knives!!!!!!!!!!!!!!!!!!!!
i have that moose one from a while back
got it from Joe in a stag handle
which makes it quite nice
gee that is an odd pink wood or is it the pict quality?
should have gotten the stright blade for my tackel box
missed it as had company drop in for a few days
on his way back to wv now and i am finley able to get ready for th e
