By the way, if anybody does their own photography to submit to the publications this background removal stuff can be VERY important. I have submitted a lot of images over the years and just wrote a feature article for Knives 2021. If you flip through that book, and its predecessors for the last...

That is actually not bad at all for green screen. Normally with green there is some reflecting or tinting spilling over on to the knife. I struggled with the issue until I remembered that the reason they mainly use green is to avoid losing human skin tones which have the least in common with...

Which would have to lead us to also ask what techniques or guidelines should be considered to mitigate the stress induced by forging; when many would say that the effects of forging would make a better knife. As Ed pointed out, the only real difference between the two is the size of the area...

Actually, I have read articles describing etching and magnetic powder techniques used in forensics to deal with those exact situations.

What Ed said. If you look really close you can see the distortion of the metal around the stamp, with strain effects visible at the surface. But also, when you begin to hand sand over the stamping the displaced metal that was raised up around the edges becomes quite evident. The crystalline...

Park Metallurgical/Heatbath AAA should be heated to the 120°F to 130°F range, I would not go much cooler and would get concerned if it got to 150°F. The challenge of keeping it cool is why I never recommend buying quenchants in less than 5 gallons. I personally don't believe sellers should...

I am obviously a forged steel guy but I've done enough testing work for myself and clients to make some observations. Removing iron oxide scale will save on belts, and also be aware that where there is oxide scale, there most likely be decarb on some level. That hot rolled bar stock with the...

Last year Tim Zowada and I visited a guy who laps those things to certify them for incredible tolerances. It was a real treat to watch him work because, believe it or not, the most accurate lapping is still done by hand with a cast iron plate and carefully applied diamond powder. He checks it...

Metallic contamination will not show up later, it will appear in the etch and if it is Cu based it will be pink. Metallically contaminated etchant is essentially a very weak electroplating process, in this case with copper atoms in the solution being deposited in the surface of the steel. Pure...

For sure. Years ago I wanted to do my own website so I taught myself HTML, it wasn't that bad, to me it seemed to be where the old "basic" programming language went to. But then I took a few years off and along came CSS, Java script, and php...o_O. I was lost! Heck HTML even changed so much...

I am currently building a new website for the ABS using the Wordpress format, I have been using Wordpress for many years now and thought I understood it, but a project as large as the ABS site has been a serious education. Here is what I have found- You can do just about anything with this...

Interesting that you noticed that, since such is often the case in any trade publication. Let me share a story from the Underwater Basket Weaving Community that may, or may not, be true. Years ago, the underwater basket weavers had a magazine called “Weave Under Waves”, not sure if it is around...

:) That is good to hear, watched about 5 minutes of that joker once in order to spot that he would do any ridiculous thing for the camera just for shock value, regardless of how dumb it actually was. Sad thing is, people could get hurt copying such an "expert". I also got the same impression...

I hope you are right Chris because, to be fair, I hear from folks in other fields that have the same complaints. It would appear that if there was a magazine for underwater basket weaving the people who really understand aquatic weaving would tell you how ridiculous the articles are in their...

It's always been that way too Ed. Over my career I have seen some rather lackluster talent made into stars by the mags after they spent enough money on advertising. The only guy who was ever completely open and honest about it was Bud Lang. I will always remember the conversation where Bud...

In the words of the late Kurt Cobain- "Here we are, now entertain us". As a culture we really don't give a darn about actual information, we just want to be spoon fed pablum that makes us feel good. Thus the rare individual looking for knowledge, or even the occasional fact, has to really work...

Yet another great reminder why I don't read that magazine anymore. Folks need to realize that it has never bee a requirement that you actually know anything about a topic to write for that magazine; indeed the evidence would indicate quite the opposite. I have seen this argument before, and it...

Two words- muriatic acid. This is basically a really cheap form of HCL. I will not allow a container of this stuff to be opened anywhere within the four walls of my shop, or I will be cleaning rust off from anything iron based at surprising distances from the acid. FeCl is essentially very...

Hello Mike, As some have pointed out, adding some thermal mass to the oven will help even it out. As will waiting for the oven to fully equalize and come to a hold before introducing you blades. But if you have an actual heat treat oven, that would be the thing to use. What I might do in your...

Here are some micrographs of annealed 1084 to illustrate what I am describing. It is not as pronounced with 1084 but other alloys, especially those with chromium, will really stick to the outlines of the previous carbide structures.
