In what way might we create a better tool for both slicing cake and shifting the slice?

Good shape of the slice.

  1.  slices cake neatly. 

  2. can pick up cake without deforming it.

  3. sharp for precise cutting.

  4. sharp enough for scooping up the slice.

  5. changeable knife shape.

  6. can cut variable sized slices.

Everyone can use.

  1.  not too complicated, so everyone can use.

  2. safe enough for children to use.

  3. (!)light weight.

Good for successive uses.

  1. non-stick so that crumbs don't stick.

  2. (!)comfortable for long use.

  3. good grip for holding the tool.

  4. (!)can pick up multiple slices at a time.

  5. should not need too much force.

Specifications for moving slices.

  1. no extra force on the cake.

  2. has a good grip on the cake.

  3. lets go of the cake easily.

  4. generally quick and efficient.


  1. easy to wash.

  2. small.

  3. easy to store.

  4. (!)looks nice.

  5. easy to hold.

  6. hygienic.

  7. non-rusting material.

User Feedback.


User 1:
The lift :
Grading : 3
Feedback : takes time, tedious to lift unless there is a support.
The Twister :
Grading : 4(its pretty cool) 
Feedback : needs some improvements, cuts and picks up slices efficiently but slices tend to stick to it.
Tongslicer :
Grading :4.75 or just let it be 5 =P
Feedback : WHAT DID U DO WITH ALL THAT CAKE, I DIDN'T GET A SINGLE SLICE!!! cool tongs, never seen anything like it before. Could be just a little bigger for big slices and it would be nice if it could cut different shapes. It's really good though, I must try it!!

User 2:
I  liked the tongslicer best.

User 3:
I would buy the tongslicer.

User 4:
The twister seems best out of the choices, because the slices are equal(in the case of a regular shaped cake) and it is quick. but different cakes would need different shapes.

User 5:
The sweep will not work due to icing, if any. Also, the lift is pretty much pointless.
The tongslicer is good, but the slices must be either rectangular or 'V' shaped.

User 6:
The concept of the grip in the tongslicer is good, thus the tongslicer.

User 7:
The twister is the best because of how quick and efficient it is.
(this is my dad, one of the very,very few people who actually understood the real concept behind the Twister.)

User 8:
If I had to rate them,I'd be most likely to buy first the tongslicer, second the lift. Least likely is the twisted,because of its complexity,it might not do well in the market. But it has the wow factor.
