My LL Bean fleece lined winter jacket my parents got me when I was 19. I’ve treated it like crap and damn thing still looks good, nice and warm.
My Sharp Microwave. My grandfather bought it in 1975 (i'm a year older) and I still use it 2-3 times a week. It's a damn tank
I have an old cheap 2 cup Mr. Coffee I inherited from my grandmother in 1998 or so. I don't drink the horrid shit, but I've made a cup for my wife every day since 2007. I've even cleaned it 2 or 3 times.
Coleman cooler from the early 70's. Timberland steeltoed work shoes. The fit is perfect. 1st gen Sv650 racebike
My Benchmade Griptilian pocket knife. Great locking mechanism, perfect size and fits well in my hand. My dad's old English made bench vise, ugly and beat up but never fails and been part of countless projects that would have been impossible without it. I have a pair of long reach bent nose needle nose pliers from Snap-on that I seem to always grab. They have bailed me out 100's of times too. Just traded in my 07' Tundra and it was an amazing truck, never failed me.
HP calculators. I still have working HP-25, HP-34, HP-41, HP-12. The oldest was bought in 1975. My 2004 GSXR600 race bike. - it took a beating and still ran great. Pretty much anything I actually take care of works.
Bel-Ray salt water proof grease. Still have a tub from when I started racing motocross way back in 1980. The stuff looks brand new when I open the tub. Still using it.
My Leatherman OHT multi-tool. Quite possibly the best multi ever made. It's big and heavy, but after carrying it forever, I don't even notice it on my belt anymore.
