Good point, or as that most irreverant of american american poets might say "well spoken well said..."[chevy chase] while I do place a lot of stock /" faith" in my rs, failure of equipment is always in the back of my mind. Thats why when I put a blade on my pants belt I always have something of equal or simular value in my A bag. It also helps when OPONCONed out. Their "smaj" may have a problem with our gear but once the wire is cleared he ain't gonna be there. and if he is, he won't!
I am a fan of the rs, but for all this typin' I should state some caveats, If your looking for a basic camp knife its a good bet. If you want a Johnny Recon fighting knife... Do what Al Mar said, take what your issued, sharpen it well and train with it . Then use it only as a weapon. I am a big fan of the M7 for that. The blade shape has been a crowd pleaser since the stone age; I'm also much a bigger fan of the M95, A1, and Raven midtech.
Now that the rants over - - - Pack two. Carry one and keep the other where you can get it - Murphy never sleeps, but you have to.
