The English Dialect Dictionary has several definitions for scute with origins in Dorset, Somerset, Devon and Cornwall:
1. A sum of money, a present or reward
2. The metal shield for the heel or toe of boot or shoe
3. The iron point of a wooden plough
4. A small patch of leather put on the sole of a boot or shoe
5. The outside piece sawed off a balk of timber
None of these definitions really fits, especially as there are ten of them and they are specified as being of iron. They were found in the kitchen along with the bellows so maybe something to do with kitchen life.
