My biggest three : ProTo, SnapOn, USA Craftsman
The other fourty: USA Allen, Bonney, Channellock, Diamond, etc
Then there are those China Shoppe and dime store tools that sneak in..
All my tools were purchased to either serve a current purpose or fill gaps in tomorrows needs.... My 3/4 and 1" drive impact sockets are a classic example: I have inexpensive sets in metric and std to cover most any job. If a socket breaks, I replace it with a ProTo. But I cannot justify buying a full set of ProTo impact sockets, and then possibly not use most of them.. I have my favorites and dislikes spread amongst the different tool brands based on durability, need, fit or feature, price, access for purchase and dealer support, and a made in USA imprint pulls allot of weight with me... BUT I DO have my favorite cheapo tools; I have no idea how many packs of HF orange handled pliers I have bought over the years... I give them as gifts and use them to save wear and tear on my good tools... I like their pneumatic cutoff wheels with the steel guard. I mentioned the large impact sockets. I was going to order these from Sears a few years back.. I wasted two hours on their website trying to buy them online, and have them shipped to the Grand Forks, ND store.........emails to their customer were ignored... Sears pissed me off so I went to HF and bought the sets I wanted. NOT everything you see when you look at a tool is evident; is it?? I don't belong to any tool fan clubs.... I just have my likes and dislikes.. Expensive doesn't always mean the best, as my two poorest lasting air tools have come off the SnapOn truck.. I hate my ProTo slipjoint pliers to the point that they have spent the last 35 years in two pieces in a junk tool drawer.. But the ProTo sidecutters are my favorite.. I looked at some raised panel large metric combination wrenches at Sears a few years ago.. They had edges sharp enough to slit your finger open... I seen that and didn't bother to pick that USA trash off the shelf.. It may not be a premium tool, but it should at least be safe to hold in your hands... The regular sized China sets of raised panels aren't that bad, but they can stay on the peg too. I bought raised panel wrenches back in the early 70's that put the new ones to shame.. Like I mentioned, I have my likes and dislikes...
If I had to choose one brand to stick with, it would be ProTo
