    Recycled steel

    IMO, "a mess of contradictions" We do have to "get into 10xx vs, 5160 vs. 80crv2" because that is partially what using a known steel is about. Are you making a large chopping blade ? Do you want to pull an hamon ? Are you making a thin (1/8") EDC that has to be tough despite its light weight? How much Mg, Si,V, Cr, is in your mystery steel? Is the mystery steel deep or shallow hardening? Is it worth the time to make the knife and find out it won't pull an hamon, or make a test piece when you could pull a piece of 1075 and get there quicker? Can you actually tell a customer that a thin EDC blade from mystery steel is as tough as one from 80CrV2 just because it was quenched and tempered the same? I suppose you could make two and break one to see but if it isn't that's a lot of time wasted. You decry the lack of precision in the "decalescence then quench" method and apparently using a separate oven thermometer for tempering but somehow using unknown steel doesn't throw another large degree of imprecision into the mix? The funny thing about the decalescence argument is that, with many of the most common carbon steels, it is the decalescence point that you would be trying to get to if you had the high temp oven. At least in an open forge you can confirm it happened. Granted some steels like soak times that are hard to arrange in a plain forge, but those with just forges tend to avoid those steels. Of course if all you know about a mystery steel is that it will harden you don't know if it wants a long soak or not. I think a lot of makers will tell you that they have found differences in desired aspects of known steels using basic equipment. Those differences do exist and help us determine which steel is best, within our capabilities, for the knife and it's intended purpose because there is no "perfect" steel. We go a long way towards matching the steel and it's qualities to the task at hand if we know what steel we are starting out with. I think you and I might agree that there may be a bit of obsession over increments that some only think they are in control of and may only believe they matter, but the composition of a steel, the hardening and the temperature it is tempered at after hardening are variables that we can keep a tight reign on. A pity to toss any one of those aside unnecessarily.

    Recycled steel

    I don't have a heat treat oven beyond my toaster tempering oven and I have gone almost exclusively to "knifemaking steel" because i find quite the opposite result. 1080, 80CrV2, etc have all of the details worked out to heat treating and, surprise, they don't require more than my forge, oil, toaster oven, oven thermometer to get darned near as close to optimum as possible. With mystery metal I'm never sure what it wants and part of the time mystery metal, if you could identify it, would be more complicated than the aforementioned "knifemaking steels" to optimized. There are reasons one might use mystery metal but none of those are because knifemaking steel is more complicated to heat treat.

    For making some tools it makes sense, like using a tire iron to make a spring fuller. Or the scorps from wrenches or a sen from an old file. I still have some salvaged coil and leaf spring to use for something. I may getvaround to a bowl adze or two.

    resurrection

    I really appreciate seeing tools, axes, knives, swords (or whatever) made by someone who actually know HOW they were/are used. The details of hands-on use and experience makes a big difference that separates those items thusly made from those made by someone who just copies the shape without understanding the purpose. Obviously you are both a craftsman and a purveyor of living history. Bravo!

    Great. I'm a bit of a rebel when it comes to the whole design/balance/ergonomics thing. I think that. A lot of times, when people aren't happy with what they call "The balance" it is actually the ergonomics of the handle to blame. Since you are basically working with a unique design you shouldn't hesitate to make the handle work with the blade by doing exactly what you said, taking your time with it. If I were doing it I might even use wooden doweling to pin on some scrap wood and ""fiddle with it" until I got a shape that felt right. No sense in going to all the trouble to make a good blade just to stick on an awkward handle. "Form follows function".

    Ghadzooks I forgot Alan Parsons Project (Tales of mystery and Imagination), Jethro Tull (Minstrel in the Gallery, Crest of a Knave) if you have Scottish genes you must listen to "Mountain Men" from Tull's Crest of a Knave.

    We have exactly one radio station in theses parts. Sometimes if the weather is right you might catch the PBS station so I depend on the music of my youth and even older stuff that my Dad collected. Between my mom's and dad's music when I went to school I was confused. I didn't know whether Glenn Miller or Bob Wills was President. So, like Dad, I listen to music that was important in my youth. Bob Wills, Jimmie Rodgers (the singing brakeman), and then move to my era, Eric Clapton from the, Yardbirds to solo, B.B. King, Deep Purple, Asleep at the Wheel, Zepplin, the Dead, Creedence Clearwater Revival, the Nitty Gritty Dirt Band, Steve Miller, Thin Lizzie, Charlie Daniels, Elvin Bishop, Marshal Tucker Band, the Allman Bros, Canned Heat. Older Santana, Jimmy Buffet.

    Hammer materials.

    I've got my fingers crossed. You could have the coolest set of hammers.
  10. I just can't help myself. That bronze piece makes my think of a late 50's Cadillac. That's not a bad thing either.

    Just eyeballing of course but with the tang tapered I don't think the weight of the handle end is going to be an issue. I can't say for sure bot it looks like the tang may be a smidgen wide, depending on the intent with the handle.

    Pretty sure the katana was from first season. Waiting for Doug to say, "Your knife will.. filleeet "

    Geometry question

    Last night there were several episodes, some from the first season IIRC, including both whacking bolts and brass rods. I have to question the usefulness in chopping a brass rod as being any consistent measure of value. There would be issues of alloy content of the brass, how it was clamped and how much extended, variable amounts of force. Even if it were clamped as in the flex test there are too many variables. It actually could be seen as a test of the brass rod. It one knew the alloy of the steel and it's Rockwell hardness that is actually what it would be. The flex test on the other hand is completely a measure of the blade itself and the reaction of the edge to the pressure needed to flex the cutting edge. It actually could be done with any grade of brass or a material other than brass since it is only the steel being tested. Brass is convenient and the edge of the blade digs into it to prevent the blade skating down the rod.

    Hupmobile leaf spring come back to Life!

    I really like it. The curves are very "organic" and the fittings are classic. It looks like a high end custom piece from a time long ago.

    Geometry question

    The real brass rod test, (disregard FIF) involves putting the sharpened blade down on a brass rod, held in a vice or fixture, as if it were a sharpening stone and pushing down on the blade until the cutting edge flexes. If it stays flexed then the blade is too soft. If it chips then the blade is too hard. Not a dramatic as whacking the brass rod but a lot more useful and consistent.
