This comes up ever so often.
I carry a couple ( not at once )
Rat 2 , Kabar dozier, sometimes just a case sodbuster.
Prolly my favorite is the kabar, rat 2 being a close 2nd.
Not sure how long the kabar has been available with d2.
I picked one up the add to the rest.
Solid lockup. Maybe the coating with last better than the rat2 does.
Last week smkw had them for ~$27.
