I have been carrying my 484-1 Nakamura literally every day for just over a year, I don't go anywhere without it. I haven't been bitten yet. I find that if you you simply twist it inwards, away from your pocket seam as you draw it out, it pretty much takes care of it. A couple pairs of jeans have tighter pockets so I just twist a bit harder, as long as you are conscious of it, you can avoid any incident.
The way I grip it might also help, I stick my thumb into my pocket against the scales with my other four fingers outside to ride the clip as I twist and draw, almost like the way you would grip a screw driver as you twist it, this keeps my palm basically over the spine of the blade so that if it does snag and tip a bit, it tips the spine of the blade into my palm, thus stopping it from tipping out further. I suppose every knife has its quirks and its ways, I personally love this knife. Changing out the thumb studs is another solution if you can find some that fit the diameter of the holes.
