Hey guys, after finding very little about stir bar webbing implants on this site and for that matter, anywhere else, I decided to go ahead and try it.
I opted to put the magnet in the webbing of my right hand, as my fingers are super skinny, making a regular implant hard for me to do. Not only that but the pain factor just complicates it even more. Before this came my two failed attempts at putting a gold plated 3x1mm N52 in my fingertip, one try with a scalpel and the other with a needle, I decided to try something else and see if it works. It took no time at all to do the actual implant, as all it took was marking the implant site, inserting the needle (leftover from tag injection), taking the needle out, and pushing the magnet in. A few minutes tops. To make sure I didn't get a nasty infection everything was soaked in hydrogen peroxide, I washed my hands with warm soapy water, and the site was sterilized with iodine after gloving up my needle hand. After the implant I cleaned up with alcohol pads, applied some triple antibiotic ointment to the site and put on the band-aid.
My biggest worry is sensitivity, since after all my fingertip is way more sensitive than my webbing, but I figured it was worth a shot and if it doesn't work I can just take it out. I'll give some updates on sensitivity as the healing process goes on. If I were to do this again I'd definitely opt for a bigger PTFE.

Also have some pictures, a little bit of blood but if you're on this forum you should be fine with that :p
