I don’t have the super tinker, but I do have the compact, pioneer x, and the deluxe tinker, and if I had to choose between the three I’d choose the pioneer x. The 93mm alox models have a bit more blade, the inline awl, and are more durable. If you are ok with a little more weight and sacrificing the tweezers and toothpick (both are easily carried in your wallet), go with the pioneer x. As for what I use them for, it’s the daily stuff we encounter, and the fact that the three models you mention all have scissors tells me you have figured out just how useful they are...for me they’re a must have. If you’re like many of us, you’ll buy a couple different models until you have your needs figured out, but luckily a SAK is an affordable tool. I have them in every vehicle, travel bag/backpack, my wife’s purse, and all over the house.
