a slightly larger peanut would be a jack in cv steel. take your pick: swell-end, sway back, serpentine. but my advice: get another peanut. no, two peanuts. you'll never know if you'll get another chance at making a great gesture like what you just did.
there is something about giving away a second-hand knife that you like to a non-knife person. the love seems to pass on automatically. i've given away a buck 301, a 371, a vg-10 delica, and a case toothpick. the owners don't carry them around: they put them up for display.
