  1. Here is the knife I made for myself. I broke off quite a bit of tip when trying to straighten it - we only had time for a 30 minute tempering cycle. I also did not have the right clay at the shop, so the hamon is not particularly inspired. However, it performed well against the purchases from the farmers market :-)
  2. A woodworking friend was visiting me in the shop and we spent a day forging a couple of kitchen knives. I don't have pictures of all the steps. We started with 4.5" of 3/4in round bar (W1) and forged an integral bolster. Blade lengths ended up between 6 - 7in. Here are some photos starting with normalizing and then fitting the cocobolo scales. The bolsters are hard to see and we had very limited time so everything was a little bit rushed: We hand filed the bolster to create a better fit with the wood and then drilled holes in each scale: Glued up with slow setting epoxy: The final result. The hamon on this knife did not work out as the clay came off during quenching. I'll post a photo once the other knife is done: If you think the process may be of interest, I could make it another video project.
  3. Out of curiosity what happened with this? :-)
  4. Actually, it's mostly mild steel I run through to carborize it. However, I had some failed attempts that I ran back through as well.
  5. Yesterday morning was a hearth steel morning for me. I ran two 1kg charges and had success with the two pucks that came out of it. Here are my 7 150g charges - recycling some material that did not work from a previous run. The little charcoal furnace in action. The two pucks I got out of two runs. Somebody asked in another thread how to reduce carbon. I find it very easy to produce wrought iron with this process. Pointing the tyuere down too steeply or running too much air through it quickly ends up removing all carbon in the steel.
  6. It's packaged up and will be with USPS on Monday. Enjoy! (The terrible flaws I mean)
  7. Happy New Year everyone! After a very exciting random drawing, Ryan Hobbs ended up being the lucky winner of the terribly flawed hearth steel knife. Thank you all for participating and humoring me :-)
  8. One more day if you want a chance of being the lucky winner of a terribly flawed hearth steel knife. Terrible is perhaps a little exaggerated. Fatally might be better :-)
  9. Now that you unearthed it, it certainly seems like it wants you to finish it. That certainly would be good practice for the next one. Looking forward to progress photos.
  10. Are you worried about evaporation? When I use my side blast forge heavily, the water needs to be refilled quite frequently. The heavy gauge sheet metal (I think it was 1/8in) from our last side blast forge lasted over ten years before it rusted out.
  11. If you want to participate but don't have social media, please post your explicit interest to participate in receiving a terribly flawed knife. I will give everyone a number of raffle tickets. If you don't post to social media, it will just be less raffle tickets. That's what combining computer science with knife making gives you.
  12. Posting on FB with a link to the video would be okay as well. Just reply here with they link so I can include it in the tally.
  13. It's usable in the sense that it will not break under normal application but there is at least one spot where I expect a wari to be hidden. The edge is hardened but this batch of hearth steel was not super high in carbon after all the forge welding. As for Instagram perhaps you need to also start looking into Twitter :-) I don't think that Instagram allows sharing of video. Otherwise, be creative about sharing the video. Reddit would be fine as well.
  14. I had mentioned this on the other thread already. I made a hearth steel knife that has pretty bad welding flaws and I will not do anything with it. If anyone here would like to play with it, please read further. The knife has a blade length of 8in and spine thickness of ~3/16in. The tang is about that long as well - you should cut it off to whatever length you like. I am happy to ship it to the continental USA. If the shipping is not too expensive, I can ship for free but you should assume that I may ask you for $10-$20 for shipping. While the knife is free, to participate I would like you to do the following. Tweet this video: with @NielsProvos and #bladesmith and then reply with a link to your tweet here. The winner will be drawn randomly*. Here are photos of the knife but they are a little bit misleading as you cannot fully see all of the welding flaws. Deadline to participate is the end of this year in PST. Also, if you end up doing anything with it, share your photos. Thanks for humoring me. Included at 2019-12-31: - Zeb Camper - Joshua States - Ryan Hobbs - Gary LT - Garry Keown - Andrew W Included without social media - who likes social media anyway? - Will Wilcox - Adam Weller *: I will use a raffle ticket system where a post to social media leads to more raffle tickets than those participating without social media.
  15. Blade is 8in long. Spine is 3/16" thick.
  16. The failure is a bunch of welding flaws. The tang is forge welded on but one of the tag welds to hold it did not disappear.
  17. My last experiment with turning hearth steel into something usable failed miserably. I polished it up anyway. Now, I wonder what to do with it. It's hardened and has a simple sugu hamon. I was thinking of organizing some kind of give away for anyone who wants something to play with. Any other thoughts? I could just put it in the drawer of failed experiments as well :-) You can't tell from the photo but it's quite beefy.
  18. Probably half of the tongs I made recently are 3/4in for the jaws and boss than 1/2 round that I forge weld on. I cheat though because I place a tag weld to avoid the dropping tongs dance.
  19. For this video, I wanted to keep it simple. Usually I draw the reigns out on the power hammer and for forge welding, you definitely need tongs already.
  20. I love the books. They were the guide my blacksmithing teacher used.
  21. I love bow jaw tongs for holding the tang of knives or swords. I decided to make a video on forging them - following the Mark Asperey approach: Let me know what you think.
  22. I am glad to hear you like the video. It's a lot of work to make them. Did you think the pattern visualization was helpful or was it way too short?
  23. This is a video completing about two years of work in creating a single-edged pattern-welded sword or seax that could plausibly have been created during Viking times. It shows alls steps from assembling pieces of steel, twisting and forging until the sword blade is complete and tested with a simple cutting test. It’s about 30 minutes long and shot on a Sony FS7. It’s 4K and color graded for high-dynamic range (HDR). If you like it, please reshare it!
