I have been in two weddings in the past six weeks, and got interesting gifts for each one. The first groom gave us
these. They are pretty sharp (one drew blood within 10 minutes), and came with a holster, because why wouldnt you carry a throwing axe on your hip day to day.
The second groom personalized his version of the gift, which were cuff links. One guy who fishes got salmon shaped cuff links, another groomsman got his shaped like a wrench since he works on mining equipment in Ghana. I received
these, because the groom and I share a passion for homebrewing.
When I got married, I gave my groomsmen personalized flasks, but the cool part was the little mini funnels that went with each one. Now they can fill their flasks without wasting half the bottle.
