I'm not really sure what brand is best, but I do know for a fact, none of them grow when you plant them, not even the top of the line wrenches and nobody has a "lose it and we'll give you another" policy as of yet, when anyone does, let me know, no matter how bad of quality they are, I'd probably buy one just to find out if the warranty is any good.
It seems every few years, anyone locally who sells tools, switches brands, basically so they no longer have to provide any warranty, you know "well we no longer deal with that company, you'll have to find someone that does" we now sell this brand instead.............you need it today you say, you'd better buy this brand, its better anyhow, plus the warranty is longer [not that they'll handle that brand long enough to know].
Klutch, I think at one time I had some of those, either they got lost or someone liked them enough to not return them, either way, we're onto to bigger and better ones, or so the locals who sell them tell me, not sure what brand it is this week though.
Last week I noticed I had no 3/4 inch combination wrenches left I could find, so I made comment about it, sure would be nice if some of them found their way back to my shop, turns out they did appear, about a dozen of them, just opened the bill today and found out I paid for them anyhow, go figure. Kids, help, spouse, I've figured out over the years, I should have chosen them all more carefully, those I have around now are really hard on my tools.
