Please look at the photos as to its condition. I believe this is new & never used or carried with box

There are some normal scuffing on the reverse side fro sliding into the sheath

Not sure as to the steel as I have read 420 HC or 440 was used on these knives during these years

This is a early 2012 when Gerber first changed the obverse ricasso's Slant 3 logo was eliminated and marked with "GERBER" over "USA" and remains this way through the 2020 year. The reverse ricasso has the same 2-line marking consisting of a dated production code over a 5 digit numeric serial number.

Later in 2012, sometime after S/N 09804 and prior to S/N 10653, the reverse ricasso marking changed to a 3-line code consisting of an 8 digit alpha-numeric code (unknown meaning) over a dated production code, over a 5 digit numeric serial number.

Gerber stopped making these in 2020
