Fragging tools.

I know there are some tools out there to use for fragging, but I am wondering if anybody knows of a tool like a spring loaded center punch that I can use to chip encrusted montipora off of rock with 1 hand. The spring loaded center punch is almost the perfect tool but it doesn’t have a button to “fire” it when you want to, you have to push it hard on the object and when it clicks it fires automaticly and that could be a problem in certain areas (pushing hard on a rock that isn’t solid).

Anyone have any ideas?

you could use an Oscillating tool and then modify a Carbide Grout Blade to the width you would like to work with.

Not a bad idea, but I should have clarified that I am looking for in tank solutions. My rock work doesn’t come out unless I’m breaking down the tank.
