Wavemaker Nick

Hi everyone, I'm based in Bristol UK and I desperately need some advice. I have got in my possession thousands of knives from a police amnesty we did 2 years ago. I want to now melt them down and ideally, eventually make some kind of sculpture to commemorate victims of knife crime. I have absolutely no connections (the person who was going to do it has passed away) and wandered if there are any pointers from this community. I would be so grateful for any advice Nick
