I have used both the 6LN and 5CR versions. They're kinda cheap, but my opinion would be much different if the blade was facing the opposite direction. Both the Schrade/Vise Grip collaboration and the Kershaw A-100 are fixed pliers tools with the cutting blade facing away from the pliers.
It's amazing how prices have exploded on those Schrades. Should've gotten one when the secondary market prices were like $60. I do have a Kershaw A-100; which I built from a lot of four broken tools (along with a second one that wasn't as nice, which I gave away).
