Suggestions on Staking Tool

[freedom-lover]

On the older Winchester trigger groups they staked all of the pins and they produced a nice sharp staking. I tried pin punches and the like and either they were not hard enough or did not produce a nice sharp mark. Any suggestions for a staking tool? Perhaps something that works by turning a screw with a sharp tip instead of striking a pointy punch with a hammer?

how about a cold chisel, but what you're asking for was done in a press with a die
