Okay, okay. Serious, this time.
Honestly, my Alox does all the day-to-day work that I "need", and on the weekends, it's been the QSP "Worker".
I'm honestly not sure what the third one would be. I've invested in good tools over the years, so anything that needs a stouter implement falls to the Sawzall or the angle grinder (okay, the angle grinder is pretty plastic, but it does the job), and if it just needs to be broken apart, I've got that handled, from the 24oz Estwing, to the Stanley Fubar.
In the interest of playing fair, I'll include the TOPS Lil' Roughneck as my third.
And in the interest of
not playing fair, I'm going to say this doesn't include a couple knives that were gifts, and the sharp tool on my Skeletool.
Because it's not a knife, it's a multitool!
