Reddit reviews Superior Tool Company 03943 Compression Sleeve Puller and Sleeve Remover for 1/2-Inch Compression Fittings Only

Any bag or bucket will do - it's what you put in it that counts. Something cheap is best, like a 5 gal bucket, since the tools are going to cost you...

The tools I recommend having immediately:

-Hammer (22oz Estwing steel hammer is great, I still have the first one I ever bought 14 years ago)
-Nail puller
-Flat pry bar
-2-lb sledge (if you're doing commercial work you'll be setting a lot of hangers :)
-12" or shorter level (preferably with grade marks - I like these ones
-Set of cold chisels
-Adjustable pliers (some like channellocks, but after using both for many years, I have come to the conclusion that due to mechanical advantages and better engineering, these Knipex pliers are the best pliers on the face of the earth, period. You can get a 3-pack on ebay for less than $100. But you can also just get the 10" ones which you'll use most often for around $30 online.
-"Rat-tail" file and flat file
-4-in-1 or 8-in-1 screwdriver
-utility knife (preferably one that stores blades in the handle and one that easily changes blades)
-Sharpies (or pencils - I prefer sharpies, since they more visibly mark metal)
-12", 8", and 6" crescent wrench. Get something cheap, because eventually you'll want these and they're effing expensive, so you might as well get some basic stuff now, knowing that you'll eventually upgrade when you have about $800 to spend on hand tools.
-5/16" nut driver

That's all I can think of right now....don't get too worried about getting the perfect stuff now, because as you steadily become a master of your craft, your style of organization, tool selection, and approach will gradually become more specific, and you'll go through lots of old crappy "apprentice" tools before you start to have thousands of dollars invested in super-special stuff like this, this,this, this, this, boy I could go on forever. You don't use a lot of stuff very often, but when you need it, nothing else will do. Oh, and pipe wrenches...aluminum Ridgid pipe wrenches.

EDIT: Oh I forgot! If you're doing commercial work and cast iron piping, you'll definitely want one of these.

Ferrule puller. Screw into the nut on the back, pulls off brass ferrule. I'd do that before cutting pipe. high grit sand paper 200 grit or so. Gently clean up pipe. Try a new sharkbite valve.
