I've got an old Satin Edge Dubl Duck that belonged to my great-grandpa and it actually shaves very well.

However, the blade pulls to one side in the scales and I have to be very careful when I close it.

I saw on Lynn's video that to correct this, you use a jeweler's anvil and small hammer and tap the pin to re-swage it.

If the blade is pulling to one side, is there anything special in the way one taps on the pin? Other than lightly? Could there be a point where tapping isn't going to correct the problem and something else must be done to fix it?

This is the only razor I have with this issue so I thought maybe I'd ask before destroying a family heirloom.

Thanks!
