I too have a williams (supposedly almost the same as the legendary snap on). I tried to like it but I work in mechanical maintenance and never used it. I could see it being useful for starting a screw in wood where pressure is needed. However, that's when would I grab my impact. As a result...
Flush cut pliers cut the zip tie off smoothly. They don't leave a sharp edge that can scratch you. I work on equipment that literally has hundreds of zip ties on it and I consider them indispensable.
I also have the Tsunoda KBN-150, They work well and I think are rated for up to #10 wire...
I like the smaller pliers wrench, the 10" are too big. I use them on brass fittings frequently and they work well for that. An adjustable wrench fits better in tight spaces.
As far at the cobras, I never really liked them. The alligators are much quicker to use, and can be adjusted with one...
It does, but if its not your primary stripper and you just need to strip a couple of wires before you crimp it makes for a nice multi tool. Not everyone likes multi tools but when working out of a tool bag with limited space or on a ladder you can appreciate the usefulness.
I've got both the Carlyle and Snap ON, as well as several other off brands. - There is very slight difference in the setup, but the Carlyle is the best counterfeit of the Snap ONs. The Carlyle stay in my mobile bag. Still love my Kleins though.
On the plus side, the head is smaller. I use mine on a regular basis and although a little extra torque would be nice I wouldn't be able to use it where I do if the head was bigger. I have no intention of getting the fuel model.
I'm in the commercial car wash business. Cat pumps are the way to go. They are Japanese made and will outlast the Honda engine. Ive got some that get used every day, 365 days a year and are fifteen years old. Get a belt drive unit if you can afford it.
IMO they are innovating somewhat. Milwaukee torque lock pliers have been the best vice grips I've found on the shelves- better than Spanish made proto and knipex.

This and a small bag with some accessory tools in it- measuring tape, utility knife, small hammer, a small level to help hang pictures, jewelers screwdrivers, a flashlight and maybe a receptacle tester.
