An 8-10 inch mid level chef knife. One with a single bevel made of quality steel that can hold an edge will make a world of difference. You haven't lived until you've cut paper thin potato slices like butter

One compact bag with a first aid kit, a knife, fire stone, rescue blanket and a turniquet. All really cheap, small and light and it can be life saving.

A flexible phone holder. Watching content in bed has never been more comfortable.

Clothes.

A Raspberry Pi.

• A tape measurer
• A heating pad
• A water resistant fire safe
• Decent surge protectors for your expensive electronics (splurge on UPS’s if you can)

If you are a dude and getting a bit older, then the Panasonic Nose and Ear hair trimmer. It's like 13$ on Amazon.

Asthma puffer - they are cheap, and if someone has an asthma attack (and you can have one if you don't have a history) it saves a person's life. I have one in my backpack, just in case. This was a tip from a first aid course I did years ago.

At least one GMRS radio, along with the license to use it. In an emergency where cell lines are down, that's what people will be using for communication. In the US, there are also NOAA weather stations that are very resilient that many GMRS radios can pick up. Just be mindful of etiquette, since there are a limited number of channels.

If you already have a good pedestrian vehicle: a good bike lock.

I (and lockpicking lawyer) recommend the kryptonite evolution. Good balance of price and protection.

For a step up I recommend the kryptonite fahgettaboutit.

Either way, bolt cutters aren't getting in, and portable angle grinders will take a little while because the chain is annoying to grind.

I see too many expensive bikes chained up with thin little locks.

As this commenter (https://lemmy.ml/comment/2274766) also said, an LTT Screwdriver from lttstore.com it is literally the best screwdriver on the market imo. I am a glazier. I work on glass, frames, screens, doors, security doors, patio doors... You name it, I'm all up in it. This screwdriver has been tortured for about 10 months I think, and it is solid as a rock. Nothing but great things to say about it.

Other things you should have. A good portable tool bag. I highly recommend a veto bag. They are amazing. They are not cheap by any means, but it's the last one you'll ever buy.

• Fastcap measuring tape

• A small rubber mallet

• Painters tool

• Putty knife

These two are very versatile and help in a ton of situations. I have never once used either of them for painting applications or drywall. But they work nicely for that stuff too.

• A small 9 inch crowbar

• Needle nose pliers with crimping, stripping, cutting, and paper thin holding accuracy

• Lineman pliars

• 6" blade utility knife (DeWalt and Milwaukee ones are really good). You can snap off the sections when you dull the edge and point.

• Cobalt drill bit set

• Cobalt countersink set

Cobalt stuff will go through hardened steel

• Speed square
• Small level (torpedo levels are a decent idea)
• Hardened steel chisel set
• spring punch tool set
• Metal file set

There is a bunch more I could list off, but yeah, these are good things to have.
