Recycling knives?

I have a few chunks of metal that don’t deserve to be knives. Does anybody recycle blades that aren’t worth the space they take up?

I and a bunch that I eventually had to take to the dump. Lots of frost cutlery a friend had given me.
 
Por lo general, los reciclo con cuchillos de cebo en mis días de pesca.
Siempre hay un uso según el cuchillo.
Por supuesto, siempre llevo una carpeta de calidad en mi bolsillo.
 
I used my old junkers to practice sharpening, grinding new profiles and bevels, and engraving techniques. Unfortunately, I would need a much bigger pile of crap knives to learn passable engraving, I ran out before improving much and one has to recognize one's limitations.
 
I usually repurpose bad or broken knives into other tools, most of the time, scrapers and picks. If it's a halfway decent steel and there's enough of it, I might try regrinding it into a decent smaller pattern.
 
Can you melt down a knife and make a new knife with the melted steel, or does it somehow ruin it?

It can be done.

The easiest way, depending on steel, for the common person would be to do some type of damascus build from them. I've seen it done with old folder blades, razor blades, etc....

melting it would ruin it, but reforging should be okay since there is no 'melting' involved... when you melt steel, you turn it into a liquid which generally will mess with all %'s of the alloy components

to melt it, you need a temperature of 2500+ F
forging temps are around 2000 F
 
If you melted down a bunch of rando knives and mixed them together in liquid form, would the result be some kind of hybrid super-steel?

Now that the previous post has appeared, I’m going with “No.”
 
Crappy knives that i have been given, have found, or any other knives that are deemed dangerous by me get repurposed or trashed. I don't want anyone to get hurt by them.

Knives that are lower quality than I like to use these days or that I am tired of, I give as random gifts. Nothing says "had a great time with Uncle Robert" like telling a nephew to go to the knife box and pick one out! It's the best kind of recycling.

I think forging is what I meant. Thanks.
My knife-smithing vocabulary isn't great even in my first language :D
