Snap-On 1/4" flex head ratchet with 3/8" drive. I've had one of these for 22 years only had to replace it twice (when it grew legs) fits everywhere and tough enough to use a cheater bar on it. I'm a professional mechanic this tool gets used daily on 98% of all jobs.

Victorionox keychain swiss army knife (the little one) has more uses than I can list from nose hairs to metal splinters electrical probe etc. I get new ones every year Christmas and birthday never get tired of this gift.

 

My 14 volt Milwaukee cordless drill followed by my Milwaukee cordless 3/8 impact gun.

 

Well, of all the tools I got in my "new" Snap On tool box, I would have to say the most useful is the 1/2" and 3/8" swivel impact adapters. For when you just can't fit your impact gun in a certain spot, throw one of these puppies on and you'll get that fastener out real quick.

My favourite tool isn't even mine. It belongs to the shop. Well, actually, it's the Millermatic 250. My boss is thinking of getting an argon bottle and an aluminum spool gun. Then I'd be happy, since I'm the only one at work who can weld aluminum.

As for my non-work related tools, it's a toss up between my mitre saw, and my brad nailer. Can't really do much without either one.

 

My lazyboy recliner. It has one of those handles on the side to where you can adjust the torque and speed of tilt

 

Mine has to be a 24" all aluminum Pipe wrench. Got it in 1964 and have used snipes on it and beat it with a hammer and the only thing I've had to do is replace the steel jaws about 10 years ago. It was made by Schick, the safty razor people. They were making helicopter rotor blades out of some very special aluminum alloy for the Viet Nam war and had some left over so they made some tools. It weighs less than a steel Rigid 12".

 

My new favorite tool is my Snap-On scanner. Still learning how to use it.

 

Since this is the same question as the other, I'll give the other answer I had. One that almost all of us would agree with!
The One that gets us out of the jamb, at the time!

 

The mind.

But handheld tools, my husband's favorite is his 5lb Blacksmith's hammer. What he uses to hammer out his historical weaponry with. That and his 250lb anvil along with his coalfired forgeblower (1900 #400 Champion) With those and steel, I have seen him work and create wonders with.

 

18 Volt Dewalt grinder. I have used that thing more than the original tool I bought the kit for which was a 18VDC drill. I out a cutoff wheel on it and cuts bolts, chains, just about anything without the cord.

 

I cant imagine life with out my ratchet wrench. Also, my John Deer beer can cuzzie, I think it's a tool anyways. keeps my right hand nice and warm all night, and it was only $2!

 

Got to love that 1/4" set I can all most rebuild a Motorcycle with it.

 

My Autoenginuity scan tool that hooks up to my laptop. I can view the outputs of dozens of sensors and even datalog things like High Pressure Oil Pressure and Mass Fuel Demanded under wide open throttle conditions. I can then graph them in excel.

 

Ill have to say my 12 volt dewalt drill...over 3-4 yrs of abuse and still kicking...

 

Y'all left out the Handy-Dandy-Super-Dial-a-matic-Sponge-Sharpener !
Couldn't live without it

 

Doh! You're right, mine was hidden behind the board stretcher.
