    All: It's been about two years since the death of my father. He died unexpectedly and suddenly. Him and I were working on our jointly owned boat in Cordova, Ak and he got a stomach ache. A few days later he was diagnosed with stage 4 Pancreatic Cancer. Ten days later he died. We had a few days to say goodbye. The very last beer I shared with my Dad was sitting on the flying bridge of his Boat in what was going to be his retirement home in Florida. I asked him what he wanted done at his funeral. In my Dad's characteristic humor he said he wanted me to build a Viking ship and put him on it, pushing it out to sea. i laughed and said that I'd probably go to jail for that. Then we hatched this plan. My family are commercial fishermen from Cordova, Alaska. We lived on the water. My dad always hoped he was of Viking descent. He was intensely disappointed to find out we were not when DNA tests became available. I wanted to share these pics and the video with you guys (my brothers in craftsmanship), but it was too close to the event. It was too personal. Enough time has passed, and I think it's okay to show you what we did. I say "we," because this build was like a long goodbye to my Dad. He was the woodworker. I was the metal guy. I had never built anything more complex than a small cabin out of wood. I had a lot of long conversations with him during this build. Most of them were in the form of: "I know, Dad! But we don't have time to redo that bit. Your funeral is in like seven days!" My buddy Shane Harvey designed this scale model of a Viking Longship from blueprints obtained from the Copenhagen museum in Denmark in CAD and then cut the keel and ribs on his CNC plywood cutter. He also did the dragon head and the small shields with my Dad's initials (RS) on them. The cutting of the cedar planks (each one cut on a table saw by me), the glue up, etc. took almost 20 days of intense work. I totally underestimated the amount of time it would take. All the lessons I had to learn as I went . . . Just in time I had it stained, varnished, and loaded onto my truck for the ferry ride to Cordova. We loaded the boat up with things my Dad loved. Including the very first sword I ever made when I was 12 with his help (ground from a long file), his favorite hat, a jar of peanut butter (his favorite food), and a gin and tonic in a viking horn (not traditional, but it was his drink). And then we set it on fire. It burned until it swamped, and then we sunk it in a bay that he loved. Anyway, hope you like the build. It's not a blade, but I know you guys well enough to know you'll be okay with this off topic post. Cheers, Dave PS: Drone footage by Shane Harvey.

    Yeah, soaking for that long at that temp is pretty much going to require protection from oxygen. 304 foil holds up better thanks to the Ni in it, which helps for higher heat. S35VN is designed to be used with optimal HT equipment (given the previous discussion, vacuum seems to be their intent). There is a lot of V (and thus VC) in there, and those do NOT like to dissolve (same with Mo and MoC). That is why the high temp for so long. It would be interesting to know what the microstructure looked like from the manufacturer. If the carbides are fine and well distributed, then an extended soak wouldn't be necessary (assuming stock removal only).

    OK, so I bought some of the S35VN to goof around with just to see what was what, and my first attempt at heat treating was a complete failure! I made a small (~2.5") folder blade just as a test piece. After the soak at the Austenitizing temp, all I had left was a flaky pile of what looked like scale. The pile barely had enough structural integrity left to held together when I picked it up out of the oven. I didn't have any heat treating foil at the time, so I thought I would try without it. However, I have a hard time believing that even without foil the blade would have oxidized 100% through. I have foil ordered, but I'm wondering if I missed something else. After rough grinding, I followed the data sheet from Crucible exactly: 1. Stress relieve by heating to 1200F and holding for 2 hours before cooling is still air. (this seemed to go fine) 2. Preheated at 1550F until equalized (Seemed OK at this point, but I was just peeking in the oven so I can't be sure) 3. Ramp up to 1950F and hold for 2 hours (At this point, the blade had become a pile of flaky scale) 4. Quench - I didn't get this far Any thoughts? FWIW, I am exploring this more for my own amusement than anything else. I'm not sold on this as a stainless option for folders, it was just an easy steel for me to get to play with.

    Another issue with the square box design is "cold" corners and hot spots. Curved surfaces promote swirl and a more even temperature. Do not overlook the advantages of blown burners. Venturi systems are techie cool, and, when built and tuned properly, work well and don't require electricity, but a blown system is dead simple and brute force. If you build it with some headroom, if you're not getting enough heat, add more air and fuel. Have a look at this thread I also want to say that you don't need a long forge or a big one (big volume) unless you have a specific need for it. My "everyday" forge has a 6 inch hot zone with two doors. I have forged a 32 inch sword blank in that forge. It would be difficult to heat treat a blade if that length in that forge, but that's why I have a long HT forge. In fact, I have four forges. A HT forge, my "everyday" forge, a welding forge, and a two brick forge I use for tiny projects, like springs.. Geoff

    It has been a while since I last posted any work here, probably because I haven't done much knifemaking for the past couple of years. However, work suddenly dried up in August, and a prayer revealed the answer: "Make knives!" What sort of knives? The market is stuffed with makers. Again I got an instant answer: "Burger, wake up! Make multiblade folders!" Well so I got back into making knives and it was a struggle at first. One of the prime reasons I stopped was that I just couldn't see up close any more, and my reading glasses, no matter how frequently I changed them, just couldn't keep up. So i learned to make knives wearing +4 Optivizors! It took three weeks and four knives before I was used to working with them. Enough history! This weekend is the largest knife show south of the equator, the Brooklyn knife show in Pretoria, and I was lucky to get a table. So for the past month I have been working on a couple of special knives: The first is the second five blade stockman I made, (the first I made in 2012/13) this is knife nr 11 of 2019, and I am quite happy with it. The damascus was made by Henning Wilkinson. Brass liners, bronze pins and MOP scales. a Then, just to be completely insane, I decided to make some knives i have never attempted before: a split back whittler and a four blade congress,and since both are my first attempts, I just had to use damascus for both. The congress has warthog tusk covers, the blades are crushed w's damascus by Stuart Smith The split back whittler has paper micarta scales, the blades I made from a bit feather damascus I had left over from when I made my first five-blade about seven years ago. Thank you for looking, questions and comments welcome!

    When the smoker door catches the cord for the meat thermometer and yanks the turkey out of the smoker. If no one else saw it hit the ground, did it really happen?

    Gerhard, I learned one very important thing a couple of months ago. I watched an interview of Tony Bose on YouTube, and the guy asked him how long he takes to make a single blade folding knife. Tony said he takes three days average. Now he is considered to be the best slipjoint maker alive. I always thought a single blade can be made in a day, two days max. After watching that video I slowed everything down and my quality jumped to a new level. To make a good knife means taking the time to do everything right, right from the first step. So my advice: don't rush it.
