BD1N is not bad but it is a "kitchen knife steel".It's a class below VG-10 and kind of like AUS-8 I heard it put once recently. I would definitely say, for the average dude, S45VN is a better steel. BD1N would serve a specific purpose.
It would help to know what your needs are. The PM2 is not as big as it seems, but has a more ergonomic, large handle. I like it. Are you trying to save every single oz that you can, do you notice the difference between a 2oz and 4oz knife in your pocket? Or are you like me, where short of a pound or two, I don't care about weight if I like a knife? Because, the base model of the PM2 in S45 is super light to me (3.75oz is the G-10 for ref, my heaviest PM2, copper scales, weighs almost 8oz, like a Buck 110 or Leatherman and I don't see those as heavy). Or you could get the Cruwear PM2 for like 5 bucks more than the reg. S45, that is production, not a sprint.
That one is groovy. Super tough, cuts well, but not as long as S45, sharpens really well. Better than VG-10 or BD1N and is "friendly to beginners" compared to S30 series while still being great. Lots of people love it. One issue, cannot switch scales yet on Cruwear Micarta cause of full liners, but the Micarta looks great. Give us some more info, what are you looking for in a knife? I know when I got my first PM2, I just wanted a Spyderco and a super-steel! Ha. Welcome here
