hi Lureman. The first mold for the
Endura ran from 1990 to 1998. The handle remained the same although we made six changes to the clip over the 8 year period.
In 1998, we made the 2nd mold. To date, there have been 2 refinements to the design. (Strengthening clip well and strengthening tip on serrated version). No changes to the rear of the model in between.
