That's a tough answer DD. I like 'em all.
I guess it would be;
1. Mack wrenches my dad gave me that he bought in 1968. Probably 60-65 pcs total.
2. Lincoln 180 welder
3. Mack stubby wrenches. Standard and Metric sets.
4. Dewalt 1/2 inch cordless drill
5.Snap on torque wrench that I hardly ever use.
My least favorite is.
1. a no name pos porta band. I need a new one real bad.
2. Snap on wrench set. They are way to thin across the body of the wrench.
