an electric knife - rec'vd as a wedding or engagement pressie, useless thing it was! Used to masticate any roast meat that it went near.

Gave away many moons ago.

Pizza knife-looks like a rotary cutter used to cut fabric on a mat. Useless, all the topping gets gnarled up on the blade and ruins the pizza. I guess if you wanted to work 'fast' and slash and strike it would work okay but I like to cut even/equal sized pizza pieces and always put a fresh hot pizza onto bread board straight from oven. Cutting it in a slashing frenzy would damage the formica bench tops as the round blade edges flew off the higher bread board.... .

So I binned the pizza cutter long ago.

Bread slicer that came with bread maker was 'pathetic' on fresh loaves but lethal for little people's fingers . Only worked on almost stale whole loaves! Gave away the slicer.

A thing called a Mouley Joulooney instant salad maker *PPFtttt !?.....a hard see thru plastic lidded cylindrical container with a handle on top that you 'whizzed' around and around and this turned your selected attached blade thingy inside - to slice, slash (hash up!!) whatever vegetable bounty you dropped inside. *wow ....this would have to take the cake for wasting my precious time. So stupid and endless time to wash all the bits and bobs by hand as not really dishwasher friendly.
