I found a gif that visualizes it pretty decently. You twist the bottom of the handle and the top butterflies open so you can put a blade in.
Mine also has another part you can twist at the top of the handle that adjusts the distance of the blade from the razor body to determine shaving “depth”.
I also have a Leaf razor handle with some single edge blades. The $5 pack of 100 Derby blades also fit my unbranded straight razor I got for like $15 20 years ago. They both work really well for specific things so long as that specific thing isn’t getting through airport security.
My grandfather was a barber and he gave me one of his 1960s era Gillette Safety razors. It’s a pretty cool mechanism on how you load and adjust the razor.
Form community and work to assist that community. Thinking every individual has to provide for themselves and their family is a libertarian fantasy that depends on having money to spend at a nonexistent store on nonexistent bags of seed to grow with well water you excavated by hand that you will defend with a gun you load with nonexistent ammunition bought at that same nonexistent store with no money just so you can shoot your hungry neighbor who wants food.
If landlords demand payment when no one has a job, oust the landlords and protect your neighbors who are being threatened with eviction. If police try to protect the landlord’s position, oust the police and protect your neighbors who are being violently targeted.
If people in your community are hungry, use existing farmland and existing logistics to provide enough for everyone. Sure, these workers won’t be paid if there’s no money to pay with, but if the choice is between “work hard and help my community from starving” and “sit on my ass as everyone starves”, it seems clear what logistics workers and farmers would choose. And your goal should be to assist them or assist some other facet of maintaining your community.
Alphasmart keyboard to type notes when I’m out and about then transfer it to a VimWiki journal entry when I get home with a single button
iPod video modded with things like USB C and more storage
Retro “inspired” tv. Essentially, my old CRT didn’t survive a move and I replaced it with a replacement iPad 3 screen, a 3D printed body, and an analogue scaler so I can still plug my ps2 into it. It’s not really the same but it was a fun project.
Original gameboy with LSDJ so I can make chiptunes (though at this point, I’ve replaced it with the Dirtywave M8 entirely)
Tech of the non-electric variety:
Inkle loom, rigid heddle loom, and floor loom for various weaving
Spinning yarn on a spinning wheel and drop spindles (also have a 3D printed DIY e-spinner because the spinning wheel is so temperamental)
