Grip Suggestions

Hey guys. I'm looking for some ideas for grips on my saber. I've got the 4" deep fluted extension, and I'm looking for something to put into the grooves to add some grip, and also to add a little black accent to a mostly silver hilt. I was originally looking for ideas that stick on with adhesive, but I've got no problem drilling and tapping holes if you have suggestions that require screws. Thanks for any input!

Thank you for the reply! I actually tried those, but they weren't quite long enough or wide enough to fill the grooves like I wanted. Plus, they didn't really want to stick to the part very well. But thanks again for your reply!
