Homemade or modified tension tools are my preference.
For small padlocks, and everything else lately I have been using twist-flex style wrenches made from hair pins. Just be sure to bring a small screwdriver to turn the plug if it demands more torque. These tiny twist-flex style wrenches worke excellent in the top of the keyway! I recommend them for american lock brand padlocks, as well as deadbolts! With deadbolts you usually don't need to turn with a screwdriver, just be careful... These are so cheap, useful and easy to make that I would recommend them for an emergency kit and for general use. Even if you like other tension tools or like to buy them give hairpins a try..
hehe the unbent end doubles as a wafer pick.
I also recommend brass rod, and wiper inserts to make excellent tools. Since they are custom, find the size that you think is right and give it a try! Don't underestimate alternate placements for your tension tool! Put it wherever it fits best and you can get to the keyway in the manner that you want to!
....and for wider wrenches, I find that tapering the business end works really well for a custom tool that fits many locks well. (I am unsure who originally had or posted that idea, but whoever you are, thanks again!)
Most important! If it doesn't fit the way you like, then make it fit!
