Hi
I think I need to sharpen my blades today, but I don't have any ice. Is there any other way to do it?
Many thanks
-
I think a trip to the servo for ice or maybe a neighbour has some.

Any frozen blocks of juice or fruit or anything?

Didn't Thermomixer say you can just put the blades in the freezer to sharpen them? Don't know how long he meant though.
-
Thermomixer did say that JD and it would work, you would need to leave them in there long enough to chill them right through so would be a little while ;)

Fee told us about putting them in the freezer at a cooking class. I think she said about 10 minutes should do the trick. :)

I have never heard of putting the blades in the freezer to sharpen them.How does that help?
-
Have no idea Cornish Cream, I just take all suggestions on board trusting that people know what they are talking about :P :P :P

I was told once that the blades were shaped/crafted at a very cold temperature, but will naturally change shape as they are heated and used. When the metal blades are returned back to that cold temperature they are designed to return to their original shape. I guess with that theory the blades aren't being "sharpened" by cutting hard ice, but are being reshaped by the coldness. It does make sense I guess as the blades aren't overly sharp to touch and seem to rely on the angle of the blade and the power of the motor to chop, grind etc.
Whether or not what I have been told is actually correct may be another matter altogether though. ;) ;D

That's the story Chelsea, well said :-* :-*

Thank you!
:)

Thanks Chelsea for the technical info,doesn't harm to try it.

we need to ask the question then - can we put our good chefs knives in the freezer to sharpen them (or is this different?)
-
it's because of the type of steel (i forget what it's called) it has a thematic memory i think? so it remembers where to go back to - unlike most knives
is it solingen steel?
-
Go to the top of the class Karen - good memory ;D ;D
all the info here is correct ;)
-
amazing the stuff that comes out when i can't remember the important things :D ;D :D

No, you can not take your good kitchen knives and put in freezer to sharpen them. It will not work as the steel is not made the same way as the thermomix blades.
To sharpen your knife i recommend you buy a double sided or two stones (coarse and fine) and a sharpening steel. None of it very expensive and pretty easy to learn how to use. I think you can find free videos on the net that will show you how to use both of them.
When your knife is sharp you should be able to make at least 20 slices out of a medium sized ripe tomato. Thats what i tell my assistants to do when they learn to sharpen knifes.
