Decluttering - Are There Definite Rules?

I have been slowly working on some deep cleaning and decluttering.  I felt I needed a little encouragement so I have been reading It's All Too Much.  I found some helpful tips and agreed with much of the book until I reached the kitchen section.  A list of rarely used kitchen items as included.  I own seven of the items on the list.  Here it is in case you are curious:

Fondue Pot
Bread Machine*
Crepe Maker
Ice Cream Maker*
Juicer
Slow Cooker*
Waffle Iron*
Propane Torch
Cookie Press
Banana Rack
Pizza Stone
Egg Slicer*
Apple Corer*
Pizza Cutter*
Grapefruit Spoons

I own the items with asterisks.  The ice cream maker is the main seasonal item.  It gets used almost weekly during the summer.  I suppose I could do without the apple corer.  The egg slicer is also a mushroom slicer and strawberry slicer around here.  The waffle iron gets used monthly for a bulk cooking session of waffles which are frozen for use throughout the month.  The slow cooker is used at least weekly.  I have used it twice this past week.  The bread machine.....I own three.  Two are purchased from people who would probably agree that it is a rarely used item.  I use mine a minimum of once a week.  W is proud to tell everyone that I often have all three going at once. 

These items do take up space in our home.  All of them are well used however.  I think the basic point of the book and good advice for decluttering is that if you use and/or truly love an item it is worth keeping.  I have purchased items with good intentions and never used them as I imagined I would.  I have struggled with guilt over the wasted money.  Keeping but not using the item is not helping at all.  Then there are the items that I use occasionally.  Where is the line?  I need to seriously think about what I have room to store.  My house is mostly neat.  I tend to do a bunch of things myself rather than buy them premade.  Again it goes back to items actually being used. 

I am looking forward to letting go of some things I have been holding onto when I start the Holiday Grand Plan later this month.  The marked rarely used kitchen items will definitely be staying though!
