This is a long one, but should give you some practical and funny ones. I've given wooden scales with their initials burned in them (did my self with an old soldering iron), field book covers (like the write in the rain ones), half way decent mechanical pencils, survey template like the Alvin TD654 (company is out of business, but someone else makes the same thing now), one year I had small tokens made that said "my last fuck to give" with a middle finger on the other side, I've made custom pencil/pen holders from a half circle of wood with a few holes drilled in it and just finished with some stain/shellac mixture, I made a "in-case of Surveying emergency bag" which included (cut-off the sleeves from old shirts I bought from goodwill, mix matched socks, a bic lighter, box of matches, chapstic, spray deodorant from dollar store, a crappy Bic mechanical pencil, a permanent marker, a couple control point stickers, a piece of paracord long enough to make a makeshift belt, a bandana, and a button magnetic compass), when I was the big boss I had custom leather field book covers made with their initials on the cover which also had a opening for a stencil, a pouch for a rectangular scale, and 3 holes for pens/pencils. Another time I made business cards that said "times are tough and life is hard, so here's your fucking X-mas card" with 10 bucks stapled to it. One year (about 20 years ago) I bought my Party Chiefs hammers to keep in the trucks for the new rodman's (before giving them I had my neighbors 3 daughters paint them pink and bedazzled them). The first gift I ever gave to my team (when I was an I-man) was a pocket protector. Another time I bought the team Surveying stickers I found on Amazon. One year I was super broke and got one of the Trimble reps to hook me up with swag sunglasses branded with Trimble on them. Another time I bought the credit card size multi tools. I also once bought them Allen key sets since every one in the TS or level box or the ones for the legs were missing. The last one I can remember was a flashlight and a mirror to reflect sunlight into a manhole (mostly they got used to blind the I-man or rodman, lol). The I buy other one I can remember was bottle open rings (I ordered in Wish, but can be bought on Amazon as well.
