I've got an early 1990's Model 5 a four inch model that I have used to dress well over a dozen elk and twice that amount of deer and antelope. Even took it over with me in 1998 to RSA on my first plains game hunt...simply to say it had been to Africa.
Did use it though to search for slugs in dead game, and other cutting chores on the hunt.
Have a model 26 but that ones a safe queen.
