I thank all of you who replied, i really appreciate it.
The product/products that i want to create are a range of utensils that are easy to clean and dont get food stuck in gaps, not utensils that are used to clean other utensils.
Secondly, what i mean by my problem is that i find that the way some utensils are fitted together can be quite fiddly and i feel that it doesnt need to be fitted like that. For example i find many of the knives, larger spoons, graters have fittings that are two akward to get at.
I will try and post some pictures to show what i mean.
I also understand that most people use washing machines, i actually use one where i work but still encounter this problem, however i still feel this is an issue but i may be wrong.
Thanks again for the replies
