Mechanical keyboards, though about forty percent of them at this point are ones I feel comfortable saying I “made,” which is to say I did something significantly more involved than assembling a barebones kit. Still, they’re accumulating a bit and sometimes I build one just to try some small layout tweak or technique I haven’t done before.
I also have a fountain pen collection, but I haven’t added much to it recently. It’s not a bad gift vector for loved ones though, and it turns out that my Montblanc really is nice, though not by such a margin that I was ever going to pay for it myself.
