i have the TPT (and TPT Slide) and used its bottle opening cap lifter, nail file, mini pry lip, flat head screw driver functionalities occasionally. both TPT's are keychain-suitable but have several tangible drawbacks under certain work conditions, some minor of which i mentioned in the reviews and other major which i didn't mention in order not to unnecessarily harm the maker's sales. there wasn't any feedback on either awesome epic review so i am guessing that the readers don't care for this kind of edc gadget no problem. hence no need to detail on the QT other than: it is smaller than the TPT in every respect (LxWxH) and is exactly as expected whatever that means. i bought it for $17 mas $4 regged letter international shipping. Crowdfunding backers had paid like $25 mas $7 int shipping. i made a paypal currency conversion error losing €1 in the process lesson learned. bam!
