Just used my last Buck 110 blade on an old & worn Buck 560 from a friend of mine.
Had to use the old backspring as i'm all out of new ones, but luckily i still had a new blade, a pivot pin, and a bronze bushing.
The new pivot pin wasn't riveted with a hammer, but pressed using a vise and a little home made tool.
Pressing lessens the chances of damaging the handle plus it allows for a more precise tightening of the pivot, in this case to a 99.99 % bladeplay-free action.
