Screwdrivers:
1. Wera
2. Williams
I find Wera LaserTip to be easily the best general purpose screwdriver that money can buy; easily. Their handles are not real tough, so the dedicated auto-mechanic may or may not tolerate that. But when it comes to turning a screw, NOTHING compares. The lasertip digs in, turns the screw, the tip doesn’t slip out and strip a fastener.
For a full time auto mechanic, I would still have the Wera’s but I would back them up with the Williams. The reason I list Williams and not Snap On is because I like the feel of the hard handles, and if you’re going to have hard handle screwdrivers, you might as well save 40% and have the Williams. If you like the soft handles, then pony up for Snap On.
Sockets:
1. Snap On
2. SK
These two are just so darned close in quality, I have never been able to bring myself to pay the difference for Snap On for sockets. I have had SK sockets my whole life, and I’ve broken a grand total of ONE. My ½” SAE socket set was my grandfathers that he bought in the late 1940’s…I still have all but one of the original sockets. I replaced the ¾” not because it broke, but because I lost it (still pissed about that). Actual performance in use, it's a draw. I will say that Snap On's chrome is deeper and nicer in appearance. But I also have many 70 year old SK's where the chrome hasn't chipped on bit in 70 years...that's impressive.
Ratchet Handles:
1. Bahco
2. Snap On
Okay same ratchet, but Bahco wins because the handle is more comfortable than the Snap On (at least for me).
Pliers:
1. Knipex
2. Snap On
Knipex just owns this category; they’re the ****!
Wrenches:
1. Proto JSCV Ratcheting
2. Wright
Okay I’m cheating by putting a ratcheting wrench in there…but I think all around it’s the best wrench money can buy period. The design of the wrench is very well thought out, the I beam design is very comfortable and strong. The open end has a stupid simple Anti-Slip design that works amazingly well, yet rarely marks up a fastener…something you can’t say about the Wright or Snap On design. The ratcheting side is BRUTE strong, and will shear a Grade 8. The spline design is very unique in that the splines are faceted. Those facets are amazing at grabbing onto an old rusty fastner like a WrightGrip open end, by digging in and just holding the fastener without rounding it off. I have the Taiwan made black chrome version of these wrenches which are out-freaking-standing. The US version is the same, but with a more comfortable beam design, and it’s properly bright chromed like a combination wrench ought to be.
For a full time auto mechanic, if he doesn’t want the Proto’s (they are God awful expensive, I’ll give you that…even the Taiwan ones), then I personally would take the WrightGrip over the Snap On’s…I think the Wright is just a slightly nicer wrench, and less money.
