My little, but useful, fungus scraper is shown to the left of a petri dish of fungus that could be scraped. This is a sturdier version of the inoculation loop that microbiologists use.
I cut a strip of stainless, shaped it, stuck it into a stainless tube, forced in a little brazing paste (https://www.sra-solder.com/soldering-brazing-supplies/brazing/brazing-paste), then torched it. For this little job, a propane torch might have been sufficient.
Brazing is a useful skill. Nobody showed me. I watched videos, bought stuff, then made mistakes.
