nothing to do with sewing but help for disabled tip

Hubby has been diagnosed with carpel tunnel in his right wrist and has had a problem holding his knife. With this in mind i checked out the cost of purchasing a set of specialy adapted cutlery for him.
TILL I SAW THE PRICE.
Even on E Bay the cost was over £20.00 for a set.
Now i had to put my thinking cap on and see what i could come up with, I had seen some at the respite home that hubby goes to once a week and noted what the handles were made from.FOAM.. Well i have some of that already that is used to lag pipes. it is grey with a slit down it for ease of opening,
Light goes on in brain cell and i set to work.
select the knife fork and spoon you are going to use, with a sharp knife cut lengths off the pipe lagging tube to cover the handles, less about half inch.
get some dux tape ready you may need to cut of some of the foam along the length of the tube to make it fold around the handle nice and tight,
rip a length about half inch wide and six inch long from the roll and start to wrap it around the tape very tightly to secure the handle. rip of more lengths as you need them, make sure its tight enough to hold the foam firmly enough. take a short length of tape and cover over the top of the foam so that the handle does not protude then go around the roll again with more tape.
do this with the other utensils. You have now saved yourself £20.00 and any one will now be able to grip their cutlery with out pain .
How can companies warrant the cost of disabled items.
please feel free to pass on this way of overcoming a problem.
