Sometimes we do, other times not, it all just depends. Tools are no different than any other consumer product. Will a Chevy S-10 get me to work and back same as a Super Duty Diesel for a fraction of the cost? Sure it will. Does that mean the S-10 is just as good a truck? No it doesn't. If my only objective is to get back and forth as cheaply as possible and haul small loads on occasion then I'm probably just as well off with with the S-10, but if I'm going to haul bigger loads or pull a bigger trailer on a regular basis and need it to last forever I'm not going to be satisfied with the S-10.
Will a $150 suit from JCPenney's serve me just as well as a $2000 tailored suit? If my only objective for it is to no look like a jake carrying Uncle Bob's casket from the hearse to the grave then yes, but if I have a $5,000,000 sale on the line I want to make an impression.
The same example can be used for virtually any product.
I'll be the first person to admit that I don't NEED Proto quality in many instances. I don't make a living with my tools. I wrench for pleasure and to maintain my tractor and equipment. Some tools get used several times a week, some once a month, some rarely. However, whether I'm using it once a day or once in a blue moon, my Proto stuff makes me happy. When I reach in my box and pull out a Proto wrench I feel good about my tools, I don't get that sense of pride and enjoyment out of A Pittsburgh wrench. I like Proto and I can afford it. Does that make the Proto worth it's price compared to the HF? Maybe not to everyone, but it does to me. I realize that isn't everyone's situation, and I respect that. People will buy what suits them same as I do.
I'm probably not going to change anyone's mind in regards to how they purchase tools with this post or any other and I can assure you nobody is going to change mine. Thus goes another day on GJ.
