hi cukita-
This is right up my alley, as helping people get through daily life skills is my occupation- and my passion! All of the other suggestions are right on!
Do you have limited finger, wrist, elbow function? What is your strongest area?
The velcro strap thing is called a universal cuff. It has a pocket to slide "tools" into- Like a spoon. This way you will only have to move your wrist a tiny bit and bend your elbow.
You can definately build things up with foam pieces if you just need something larger to hold on to. You can add very creative things to make up for lost grip as well-Tape first and then add some large and small beads and tape over the tops of them so everything is smooth and doesn't hurt your skin.
You can build up your other items in this same way- toothbrush,hairbrush handles,etc.
If bending your wrist is the problem- try having someone BEND a spoon for you and give that a try. Just hold onto the handle near the scoop part and bend in to a 90 degree angle. Your spoon should now look like a boomerang. Add some girth to the handle with tape- or foam- and you should require much less hand function to operate your spoon nicely. The kitchen workers at my facility love me for this, but its usually VERY helpful

You also might try getting a plate with built up sides or a scoop plate. This way, you push the food up to the edge and the food loads onto the spoon if you are having any trouble with"loading" the spoon with food.
Hope it is helpful and best of luck to you.
