I have worked with a lot of tool's over the year's, and have seen all kind's of speacialty tool's...I have to say my favorite hand tool's are kobalt....I used a small set of them when i worked at a foundry for 9 yr's...I usede everything from hand tool's to many air tool's.. And I trained a little in the tool & die shop..That was really cool!...Learned a little about dial caliper's, and got a little training with some bridgeport's, and some smaller table lathe's...
