I have carried a black plastic 425 for over a year and wouldn't leave home without it. I bought it used with some blade play, but a few taps with a pin punch on the pivot pin tightened it up and it's stayed solid ever since. The plastic is quite rigid (unlike the Batam Series) and not showing any signs of wearing, although I've seen some that are worn smooth from riding with coins and keys. I abuse the edge pretty often, but a few strokes on a DMT diafold brings back a good working edge, or sometimes a light stropping is all it needs. I agree with gedlicks, it's so light you'll hardly know it's in your pocket.
