Your uncle's method is the safe one. That homemade tool is probably fine if the handle is solid. A screwdriver alone is risky, it can slip. The clip lead makes sure the connection is solid before you even get close. Old habits from tube gear stick around for a reason.

So you're telling me your leftover stain is still holding up, @abbyp61? I'm jealous. Mine looked fine for about eight months, then it started to bubble up like bad wallpaper. I guess my deck just has a personal grudge against cheap fixes.

My old shop teacher swore by Snap-On for the fine tooth count alone.
