eli5 why would you want to get rid of the weapon used in a crime?

For example if you use a gun to kill someone how could the bullet possibly be linked to you thousands of guns use the same caliber or a knife even though you would feel terrible looking at the knife wouldn’t it make more sense to just clean it and continue to keep the knife in your home so it make sense that your dna is on it? in movies people always feel the need to get rid of the weapons but i think it would make more sense to keep it unless there’s something i’m missing

Guns are mass manufactured, but they’re also all a little unique. A bullet recovered at a crime scene absolutely can be linked to a specific gun based on the way the rifling in the barrel has scored the bullet.

Every gun has a somewhat unique barrel “fingerprint” that forensics investigators can record if they recover the gun itself.

If your gun’s fingerprint and the bullet found in Jimmy Knuckles’ skull match, you’re fucked.

A smart criminal will *destroy* the weapon in question, making it impossible to ever become a piece of evidence against them.
