I love my Victorinox Super Tinker, but I have never used the screwdriver much because it opens the Vic into a "T" shape which makes it hard to work in tight places. While fixing a stubborn kitchen drawer today, I found myself needing to apply A LOT of force on a wood screw to tighten it down, probably because I didn't drill the hole deep enough. I tightened the screw with my firmest grip on my screwdriver but I couldn't get it all the way in. I decided to try my Super Tinker because I happened to have it out. I found that I was able to apply much more downward force and turning power by gripping the T shape knife tightly like in these photos I took. It worked great! The Super Tinker didn't flex one bit, and I didn't have too go out looking for a bigger handled screwdriver.
