Introduction: Bicycle Chain Handle Knife

bicycle chain handle knife
a broken, unused knife blade, and an oily bicycle chain born out of marriage ...

1.
It was the bottom of the blade with two holes
was fitted to the chain pin, hammered together

I finished welding the holes

3.

3 chain piece is cut off, and gradually from top to bottom "sewed"


more idea would be to handle the development of

such a cool idea its looks cool as wel so well done

Pretty cool idea

blade is ~ 10 cm ~ 3.9 inch
handle ~ 15 cm ~5.9 inch (part three , in all 45 cm ~17.71inch)

you may want to experiment with the length of the handle may be better on the shorter, gravity distribution is better

to taste

How long is it? And did you wield the chain togheter and then wield it on the blade?

Love the idea "hate" the result.
With all good intentions. ;)
No, seriously I really love idea. But it look messy and it gives me an idea how to make my own version.
I will make mine out of a simple pocket knife.
With this kind of principle:

And then try to make it work. :)

I totally agree with you a bit neater welds would make it look awesome That said great idea looks pretty cool

too high a current
thin the chain should be thicker
can not be controlled min: 50A
For almost burned the chain

1 trick I found with mig welders when trying to weld thin sheet metal a good way to stop it from blowing thru the panel was to put several jumper leads for cars each 1 end to end & connect 1 end to the earth clamp & the other to the job. The long length of wire creates a resistance that drops the power & use a thin electrode.
I haven't tried it on a stick welder but I think it would work the same. you might be able to get a neater weld. You could also try welding spots on the edge of the chain links to lock the links & use small welds on every 2nd or 3rd to hold the strips together then you can grind them smooth after.
I often make 2 of most things I make, the 1st a prototype I'm never happy with because I see the mistakes I have made & the 2nd, I make changes so I get a neater job just some suggestions I hope it helps

Running your welds downhill will also allow you to move faster without blowing through.

You could also braze it with a silver alloy, gives you more control. If you clean it in a strong acid, you could even get a nice coating.
