Forks.

I have items for home and work:

Most of the year, my work gear is stored in the shed so I have all of these duplicated in the house.

Drills - a fullsized drill at home and a mini one for at work mostly to drive nuts and bolts.

Hand tools - screwdrivers, bits, wrenches, box cutter.

Headlamps - a small AAA at home and a AA at work.

Clothes - Like most people, I have dedicated work clothes.

AA batteries

Phone chargers - Home, car, and work. I also have multiple battery banks.

Headphones - an older corded pair at home and newer BT ones at work.

Vacuum Cleaners

We have four.

One lives in my backyard shed, for cleanups and dust collection.

One lives in my garage, for cleaning the cars.

Our house is split level, so we have one for upstairs and another one for downstairs. All to save carrying it up and down the six steps that divide the front and back of the house. These two are the same make and model.

Screwdrivers.

Somehow I've ended up with 3 laptops. It's rare to have all 3 on at the same time but it happens.

Knives, I have a lot of knives. Always looking for that new look or different blade geometry. New fancy metal or accessories. Just always been a blade or edged weapon kind of guy.

I have a bunch of bows too. Into archery as well...

Game consoles.

I enjoy collecting and modding them more than actually playing lol. Generally I suck at games.

Now I do play them. But I spend a lot more time figuring out better ways to use them and getting the best quality out of them possible, or trying to use og hardware but playing any game (like ps2 over ethernet)

writing tools

Hand lotion, lip balm.

I buy my hair gel in liters when the price goes low enough, not when I need it, so have two or three liters sometimes.

Two dogs and two cats because people left them with us. I'd be good with one cat.

Back in the vinyl phase a few years ago, I bought both a regular cover and an alternate cover of an album.

It was so cool for about 3 seconds, when I realised the record/music were the same. Realised I paid double JUST for a different picture.

Last record I ever bought

I have two teeshirts, but strictly speaking only one is required. This is because of social pressure

Coffee machines. Three roommates, each one brought theirs.

I have multiple monitors for entertainment and for work.

I have my main tool set in my utility room, a subset of tools in my main cave and another subset in my garage.

Multiple pairs of jeans.

My kitchen is well provisioned with multiple redundant utensils. Also I have a double oven.

I am in the process of expanding my utility room to have two washers and two driers.

Kidneys and thinkcentres.

Scissors.

Don't need to use them every day, but previously I could never find any of the three pairs I had. Then I realized that I have money and can go buy a dozen pairs of scissors.

Now it never takes me more than 30 seconds to find a pair of scissors. 10/10, would recommend this lifestyle.

Smoking pipes..

It's an addiction (pun not intended)

I believe that I have maybe 25-30 pipes at this point

Well, I have a bunch of stuff around here that serves no real purpose that I'm otherwise sentimentally attached to or think might be useful some day, but I'm not sure I have many duplicates, even loosely speaking.

The best(?) example is probably the fact I have 3 CRT TVs, none of which I use regularly. One is the main house TV but, since I don't use it much, I've never felt the need to upgrade it. The other two are portables that I'm keeping for if I ever get back into 8-bit computers.

Rock hammers. For, uh...reasons.

Also, as others have mentioned, clothes sets. Work wear is not what I wear on my own time, including shoes. But I could just wear one set (either work or casual) and I don't think anyone would care.

Knives and pocket tools, basses (electric/upright/electric upright), 10 mm sockets

gameboys

Computers. I could do everything I need to do on my threadripper workstation, but it's not as portable as my gaming rig. I move around a lot for work and wasn't thrilled with my steam decks performance plugged into a TV for some games. Then there is my limited home lab stuff that I could host on the workstation for a minimal hit to power consumption, but why do that when I have tons of older hardware I could piece together to do it. Then there are my multiple Atari STs that I've collected. One of them is my first computer which I've managed to keep for almost forty years. I also have a few classic macs and dozens of video games, all of which I could functionally duplicate with emulation. I like old hardware, and now it's not polluting the environment in a landfill.

Smol keyboards. Each one was my endgame, but I still like them 🤗

Phones. Got my current along with the last 3 I had. I haven't disposed of them because I'm a little paranoid someone would reconstruct the contents of each phone if I just disposed of them.

Also, burned CDs/DVDs that are useless because they don't work. I'm not good and throwing away discs, which is why I still keep them.

I thought about saying loose bread ties, but those are generally so useful for when one breaks or you just need one.

I have two color laser printers. The old one is a Dell branded printer from about 15 years ago and was about the cheapest color laser printer you could buy at the time. It has some issues now particularly with color printouts, and combined with poor Linux support meant I went ahead and bought its replacement, a much nicer Brother model. But as the old printer can still give acceptable results for some things I'm keeping it until it runs out of toner which could be a while.

On top of that I still have an HP LaserJet 4 but that's been disconnected for a while. Still prints but desperately needs new rollers.

Cajons. I have two, because after I got one my husband loved it and demanded i get another, basically. They are handy as bonus seats and as a barrier to keep dogs out though, on top of just being fun to thwack.
