Thread: The Butchered Blade

Where on the blade is the crack? If it's near the toe you could maybe make it into a shorty?

Very true. It can get in line. Shorty number 3.. Take a ticket .

They do make great shorties[emoji6]
Tell your bro its no good.... And keep it for yourself, as a later project of course.[emoji4]

While you are playing with it, hone it on a 1k with no tape and see what it looks like with a shiny bevel and spine?

I think it was always there and you just see it now.

The crack was definitely not there pre vinegar...

The crack is a cm from the heel. So its knackered..

I'll hone it with no tape and take pics..

Thinking about it, every time I cook some thing in the microwave I burn it to death. Never burnt food or my self on a normal cooker but its a different story with the microwave.

The other day I did a frozen lasagne, it came out dead, burnt to bits..

So I must have over heated the vinegar ..damn infernal machine

The boiling point of household vinegar [5% acetic acid] is about 100.6 'C/213'F.

I have a hard time thinking that at that temp it caused the crack.

I think you cleaned up an existing imperfection and can now see it.

The blade was cleaned up some time ago. It was only blued yesterday and that fracture was not their.

You can see daylight through the crack, its that obvious .

Also there is another crack in the middle of the blade next to the main crack, you can see it in the pictures.

Unless bluing does something strenuous to the metal? I dunno.

Look near the heel and you can see an imperfection on the cutting edge.

I was aware of this and knew I'd have to hone it out.

The hot vinegar caused that defect to crack upwards from the edge.

Shame about the stress crack job.
Maybe the chip became the crack from the shock of hitting the boiling vinegar, like thermal shock?
Acetic acid itself wouldn't cause that to happen. Nor would the bluing solution I wouldn't think. The key is the microwave I think. Exciting molecules is a tricky business. You probably got hotter than 100C.
I said I 'warmed' up the vinegar in my case, and thought you were using a hot water radiator to warm it up, all gentle like, like a baby's bottle kinda thing.
Razors, like my bare feet, are not a fan of sudden changes in temp. Any chip is a 'stress riser' and will be a point of future cracking if things are stressed suddenly.
As a rule of thumb, I tend to breadknife, or quick 'dress' hone bad chips out before I do anything to blades, lest they crack all of a sudden during the cleaning process.
Lost a few along the way before I started to do that lil insurance step.
