  1. Greetings Alex,

     

    Listen to the metallurgists on the forum, I'm not one of them.      But, I seem to recall reading something about chromium in steels like 5160 negatively affecting fire striker performance.   I could be wrong.  But as everyone has said, a different steel may be a better choice for this project.    Something simpler in the 1070+  range, perhaps?   But if you wish to keep trying this particular piece,  maybe you can try and obscenely long soak time before the heat treat.  Maybe get it up near welding temp and hold it there for a while, maybe 5-15 minutes?   But that is also likely to cause a lot of decarb, which is not great for this application using 5160.   This might help increase the grain size.    Then maybe leave the striker surface a bit rougher, instead of so flat and polished.   Might give something more for the flint to bite on.   I mean the whole reason the thing works is because the flint is cutting off pieces of steel.  Maybe try a sharper piece of flint ?

     

    Also, "coil spring from my mechanic", does not definitively mean that it's 5160.  Coil springs can be made from all sorts of stuff across different countries.  Like 9260 for one.  Which I'm not sure is a good material for a fire striker. 

     

    I wonder if doing a blister steel kind of cook canister on a that material would make a difference?   But most likely not for the expense, time and effort, versus buying a small piece of the appropriate steel or just an old file.

     

    As far as hardness testing.  The old file skate test to a good indicator.  Just be sure that you are not hitting scale when you are testing it, because that stuff is way hard, and could give you a false reading.  Also, if you are suffering from decarb, then on the contrary, a deeper grind might present some of the better high carbon material.  I'm not sure on how deep decarb can go.

     

    If you got a good old knife you don't care about, that you know is good and hard, you can try using that knife to shave or cut into the fire striker.   If you can cut pieces off, or make and indentation with the knife onto the fire striker, then chances are the fire striker is not hard enough.   I believe strikers are supposed to be in the 60+ Rockwell range.  Again, could be wrong.

     

    Good Luck

  2. I like it.   Think you are heading in just the right direction.

     

    Orange juice,  Sunlight, Exercise and shear stubbornness makes the covids docile.  At least that helps me every time I catch a bug...   or the bug, depends on where you're from seemingly :)

     

    Keep on Keeping on...

    Always something new to learn. Those channels are good.  I get the shutting off the brain bit.   Though sometimes I wish I was resetting passwords or fixing the email servers again.   Still code a bit, when I'm not exhausted.    You can only dig so many holes before you just stop giving a *bleep*...

  4. Hadn't kept up with the show much these days. Don't watch much TV and too busy to sleep most days.  But, I managed to catch an episode the other day.  Think it was season 9, the Blackout episode.  First I've seen in a while.   My favorite part about the show has always been seeing the forging, triumphs and mistakes included, and learning something.  And the chaos and destruction is always a plus.    Seeing the smiths go back to roots using just hammer and anvil and fire was nice to see.   The last few episodes of the show that I've watched felt rushed and more focused on the end result than the path to it.    Education, hitting hot stuff and destruction.   I'm easy.

     

    But I'm also weird and can dr00l over blacksmithing and knife videos all day.  So I guess it's possible that all the viewers at home don't necessarily feel the same way.

     

    Wish them the luck with their new season.   Spread the craft.

     

  5. Nice work on the knife Faye.

    I totally understand about the distasteful part.  Sometimes, I think it's about knowing your customer, so as to avoid unnecessary effort in widdling wood when a leather wrap would have been plenty.

     

    I think the guy copied this knife...

    Here is an interesting vid on the theory of the design, for those interested.  It's a very purpose built knife. No hijacking intended.

    Might need to chat about your fit and finish

    Yeah,  not my cleanest work.  I'm calling it a prototype.   My forge is not exactly big enough for the whole thing with the flanges opened up.  Kind of had to rush the heats.   Really wish I had a coal supply for jobs like this.    Wanted to see if it could be done without using a welder, before I tried it with spring steel. 

     

    ...

    Had an unfortunate incident on the side of the road the other day.  It was stupid and unnecessary.  Tried to walk away at first too.   The Golden Rule is a simple rule.  Wish people cared.  Or at least come to the conclusion that it's not worth starting something with a stranger that may have very different "Red Lines" than what they may be accustomed to.  

    ...

     

    But fortunately, I got the opportunity to do some strength testing.   So I picked on an innocent rock.

    Lemonade from lemons and all that...

     

     

    I bent the handle at the top pretty good.    Need to make it thicker I think.  Maybe forgo any twisting.  Stayed true along the

    length of the handle though.  No idea if the scales split or separated without undoing the leather.   Feels solid.

    Having tested all sides,  the weld on one of the flanges came apart.   Flange is still there and solid, lol,  just slightly bent.

    The Broken weld.   The grain structure looks decent to me.  Probably, just didn't have enough surface area where the weld was, or just a bad weld.   I did super quench the entire head.  Very little deformation on the flange edges against the rocks.   Took quite a bit of force to get

    that flange to turn sideways like it did.

    Overall.  Pleased with it's performance.  And learned a bunch for the next one once I get the forge built...

     

     

    Here is one I built 10 years ago.   Still alive.  Just missing a couple flanges/rings and spikes now.  This one was made from leaf spring and Sucker rod.

    Made of Mild steel.  Pinned oak handle.  Deer and Couch hide for the leather.

    10 points to anyone that can guess what the flanges are made of...

    Good excuse to get more forging in.   So many options...   Maybe we can start an idea thread ?  For those undecided on what to make...

  9. Has anyone ever noticed that places like Amazon, Netflix, Youtube, Facebook, Twitter, Paypal, etc... are not exactly easy to get a hold of?

    No contact numbers listed. Everything over electronic contact of some sort.  (Corporate offices notwithstanding).    I think they generally keep it that was because they already have your money or info, so there is no need to contact you.  Everyone else is a scam.  If they want something from you and it's not official business that you personally know something about, then again, probably a scam.

     

    The internet used to be good.

    Rear copper is a pipe and the stone is contour fit into the pipe from the inside (does that make sense) and epoxied.  

     

    It does make sense, but by the look of it, it's only glued around a shallow (if that's the right word?)  part of the stone. So depending on the epoxy and the level of use, the stone will fall out eventually, most likely under any sort of impact.  Had you enveloped the copper around the wider part of the stone, it would be more secure.  In other words, had you set the stone deeper into the copper pipe, and wrapped the pipe around the thinner top part of the stone and epoxied, it probably would never move.  That's just my take on it.   Take it with a grain of salt as I've never used stone in a blade before and I tend to be really picky.  Maybe others can chime in with better info ?

     

    Still, very nice for a 4th blade.

     

    P.S.  That wood looks very similar to American Black Walnut.

  11. 4th Knife ?   Not bad at all.  How did you attach the stone?  Just glue ?

    Only thing I would say, is that the handle could have used a little contouring so it's less likely to slip in the hand in hard use.

    Otherwise, I dig it.

  12. Bummed I wasn't able to deliver on the last KITH.  Hope to make it up on the next.   

    I like the tool idea.   How about we make a set of bladesmithing tongs?  Probably the most used tool we all use.

    Maybe either set a certain design, like box jaws/pickers/punch holders or something, or whatever is the smith's favorite.   I've had success making some out of leaf spring, so I wouldn't limit it to mild steel.   Maybe a smallish hammer or a guillotine instead?

     

    If ya'll wanna stick to blades.   I'd be down for a midsize hatchet or tomahawk.  Otherwise,  I really liked the design on this page:

     

     

    I've wanted to try that for a while...

     

    I like the idea of a sen scraper.   A very under utilized tool I think.   Always trying to get away

    from reliance on motors.

     

    But if ya'll really want to get crazy.  Lets make a File.  Forged and hand cut.  Talk about fun, huh?
