Some of the tools are OK.... Wouldn't use them in a heavy duty application without expecting replacement. I bought a few of those flip open box cutting knives from HD. Both my mom and I use them exclusively now. HD calls theirs Husky, Lowes is Kobalt. Same damn company though. Um... I guess I have a wrench set that still works.
In any case. Kobalt is a Lowes brand. Task Force is generic IIRC. Husky is Home Depot. I worked at Home Depot and here was the thing about returning products with life time warranties.
If you return Husky/Kobalt, it depends on the store because the stores generally eat the cost in some fashion,
especially on the lower ticket items. Stores are supposed to get a type of credit, but this didn't always happen with the cheaper items. Some will return them (the one I worked for) without problems, others will refuse since it hurts their bottom line. Generally, if the same tool is still available (some tools are "retired" for this exact reason) and the cost is below a certain dollar amount then an exchange will take place. Don't count on a refund though.
None exclusive brands, like Task Force, Black and Decker, Sawzall, whatever. Don't count on it without the receipt. Even if they have a life time warranty. Some brands (can't recall which) have a lifetime or limited warranty of sorts but manufacturer guidelines for honoring that warranty is strict. Home Depot has this one brand of tape measure that used to be lifetime without any restrictions on the package. However, for the store to get credit, the tape measure had to have a mechanical failure
not resulting from abuse. If it was deemed otherwise, the store ate the cost. Ever see a tape measure that hasn't been dropped?
That's why many stores will ask for a receipt. They know that no reasonable person will keep the receipt. 99% of the time, they get away with it because very few people throw a ---Cleveland steamer--- fit over a $5 hand tool.
---smurfing--- Wal*Mart does the same thing too. I bought a folding chair from them.
Their ---smurfing--- brand and the frame collapsed under my fat ass within a month. Took it back but found it was discontinued. Tried to get a refund, but because it was "deleted" from their system, they wouldn't honor a refund. Apparently I'm not using the same ---smurfing--- dictionary as everyone else because "deleted" means the product still scans in their system. It was a major ---smurfing--- hassle especially with a hungry pissed off 9 month old in my arms. The ---smurf--- won that round and I had to return later with my GF. Still no receipt, but those ---smurfs--- gave her the refund (store credit) with no hassle.
You can play dirty by their rules though.
