I decided that we should return to the shop we had passed on our first bicycle outing and see what they had. The store had a few bells to choose from. It was quite interesting how differently each sounded. While I was deciding (and it took me a while) a man and his mother were buying a meditation bell, the sort that looks like a brass bowl. They were doing the same sort of thing I was doing, trying a number until they finally found the bell that spoke to them.
My bell is 8.5 kilograms, about 16 inches high and has a reverberating, pure tone. It will fit in beautifully in a grove I walk through every morning as I go to work.
