What makes the green grass grow?
The original M9 made by Buck fetch really, really high prices...the later and current ones made by Ontario are far more affordable.
I can vouch for the wire cutter feature on the Buck model...used more than once to cut through chain link fencing and other fencing types...and for bayonet functionality, a broken tip may not look pretty, but your thrust is still going to penetrate, and the more ragged a cut the bayonet leaves, the better. Its not a knife, doesn't have to be sharp or even clean.
Are there significant differences between the M9 and the current USMC you have pictured? I dont believe I have ever seen the newer USMC skewer.
