Input:
I love this knife.  I first became acquainted with the M-37 while in the service.  From the quality steel to its razor sharp edge to the full tang handle, this knife feels good in your hand.  As a retired law enforcement officer, I carry the knife for self-defense and the multi-position sheath makes this very easy to carry.  What's not to love about this knife?  Man, I love it!!
