Mocataugen (crooked knife) build along starts NOW!

[Handforged]

No one else on board before we go a little farther? I was hoping to have a few giving it a try.

[Russ]

i would but im missing some stuff. i would love to do it still.

[Hawkdancer]

Like Russell! Only missing a forge! , quenching tank, a real anvil, and time!  Watching closely!

I’ll be on board Saturday, gods willing. Been super busy and the weather is still too cold. Supposed to be above freezing by the weekend, though.

Forgive me if you already covered it, but how do you prefer to put the bend in?  Over a male form like the anvil horn or a female form like a swage block?

Doesn't really make a difference. Around the horn will give a nice curve. I use a cylinder that mounts in my hardy for turning sharp curves. Just keep in mind, whatever curve you make needs to be able to be sharpened at some point.

If you've got a torch, a piece of railroad iron and a gallon of mineral oil, you can do it!

One of my perpetual frustrations with bent blades is the cross-section deformation. Flat doesn’t stay flat in cross section. I remember frustrating my Mechanics of Materials professor when I pointed out that plane sections don’t remain plane when a bar deforms. It is a lot harder to calculate strengths and for class purposes we could pretend, but it always annoys me to have a categorical statement made when I know it isn’t true.

My experiments have bounced between male and female forms just looking for minimizing that effect.

It is still below freezing today, but I hope to get in the shop tomorrow.

Here is something to take into account. What you mentioned here is true, the cross section of steel does deform after it is bent. However, we do the bending when the steel is still in the annealed state (soft). Form your curvature THEN we thermocycle the steel, treating it like any other knife blade,  to reorganize the carbon molecules within the blade. Three thermocycles on any handforging is average and minimum for me to "Normalize" the steel from the forces that have been imparted on it in the process of shaping and that does include bending it.  So after normalizing the steel through thermocycles, we should be back to the same structure (internally) as when we started with a blank piece of steel. I know there is some debate there but I am speaking in broad strokes. This all in preparation for the final heat, quench and temper. Which if also done properly should result in the blade exhibiting the consistent hardness without stress points that we created be forging and bending it.

His folks would probably cave if he were learning one on one with an experienced smith. I think they have experience with him "experimenting" on his own on interesting project when he was younger!  This kid has a very dangerous personality disorder known as a combination of curiosity and confidence! It's why we like him.

OK FELLERS!  Saturday and snowing like a snow globe outside. Lets get the Crooked knife started back up!   For those that are working along, let's see where you are.

[Mr. Woolery]

I’m not worried about stresses. I do multiple normalization cycles, too. It is just the geometry that makes me a bit nuts.

My family ended up deciding to do Easter today instead of tomorrow. I might get forge time tonight, and very likely will be out there tomorrow, but it won’t be happening in the morning.

I appreciate the build along, I’m just in a busy time right now. I’ll catch up soon, I hope.
