Rewarding Players On Kills

Rewarding Players On Kills - Confetti Falling on Proud Basketball Players Wearing Medals

I am working on a Minecraft Map where whenever you kill another player your sword upgrades. I have tried doing /scoreboard players add @a[score_Kills=1] Kills 1 and /give @a[score_Kills=1] 283 but it gives the player a kill and an upgraded sword. How do I fix this?
