The one I had was 52100 mono, so can't speak to W1. But the grind was surprisingly good for it being 185x44 and ~200g, robust but still a very good performer. Kind of felt like a more rustic Shihan - thin enough to be enjoyable for mirepoix, sturdy enough to handle some light bone contact. Also had some really dramatic taper (maybe more than the newest batch). Very fun knife.Any experience y’all have had with his grinds or W1 as a steel? It look mighty tempting - the wrought clad stuff is so pretty!
