This is the Medford Theseus Fixblade. An incredible knife. As solid as you know Medford to be: 5mm thick blade, made of CPM-S35VN, 95mm long. The handle is outstanding, what a grip. No need to write much about the quality, if ever you had a Medford, you know what I mean. I have no intention to live up to it, still, I wonder if such a knife ever comes to its end of life.
