Update:
Yesterday I went to get a coffee, and on the walk back checked out the encampment site.
More areas were burnt, and as it had reached freezing temperatures, the homeless guy abandoned camp, likely to go to an emergency shelter.
But what had he left behind...his valuable folding utility knife!
So, I finished my coffee, put it in the empty cup and took it home.
Here it is all full of crud, after being sprayed with Lysol:
I then soaked it in bleach for 40 minutes, flipping it every 10 minutes to get full soaking:
I washed it with soap and water, dried it, and sanded the guck off the blade:
Here it is disassembled:
Here are some of the internal components after washing and alcohol soak:
And here it is in all its current glory, clean, reassembled, with added flair.
The blade is wiggly in the holder...the dirt, grime and guck is what held it stable before.
I will never use it for anything ever, but it makes a great addition to my Hobo Knife collection.
