First for me was SAK Champ SOS kit (red), second was another SAK Champ SOS Kit (black), always kept one in vehicle.
Then this year I got my first real knife - a Military SE, and two accessories the Spyderench, and Spydercard.
My two SAK kits got refurbished this year from SAK, to repair scissors, chipped handle on one, and upon their return I gave one to each of my godson's on their 13th birthday.
Absolute delight to see their smiles. I have never since such big grins in all my life, seeing them open up all the tools on the knife.
