Mark, As I mentioned, I use a rubber cane-tip as the striking surface for my version of this tool. These are available at most well-stocked hardware stores and are about 1/2" in diameter and height. They are soft enough to prevent marking the keytops yet hard enough so dirt doesn't imbed into its surface. I've been using mine without maintenance for a few years.
