Isn't the correct term for
monster channellocks , "water pump pliers?"
I have a Craftsman pair I bought new probably 40 years ago to work on spas and hot tubs, for their fittings.
The best tools I have found for working on recalcitrant oil filters are either the exact-size 'caps' that fit into the end of the cartridge, or one of those three-arm articulating ones that also fit the end, and which grip the sides of the cartridge. I have one small one and one big one.
I agree about the prices going up, I haven't seen much that I would consider a 'steal' in some time. They get a lot of furniture donated from City Furniture, which is also Ashley Furniture, I believe. City Furniture started in Ft. Lauderdale, it was originally called, "Waterbed City" back in the 1970's.
They also get a lot of upscale luminaires from I think some importer, and while the prices are less-than new, the lights are often broken or missing parts, and there is a big sign saying, "Replacement parts
ARE NOT Available for these lights!" I would like to see them selling those for ten cents on the dollar, but it's more-like 1/3 of MSRP, not a 'deal' for incomplete, broken fixtures. I've seen tags on their stuff from two years ago, still waiting to be sold. I guess they do move stuff, because their shelves aren't overflowing. I think they act on the "sell it high until the sales fall-off" model.
First time you have a stuck oil filter that defeats every attempt at removal by every other tool you own , those channellocks WILL save the day. can't tell you how many times I have used my monster channellocks for that very purpose.
