Since the 33OT was a long time personal EDC favorite I have always been interested in 2 blade jacks. I picked up a Providence made jackmaster as an example of what was around before the Old Timers. I've always been intrigued by the Jackmasters and their shell handle construction, but I never carried one as a user. I was wondering what those of you who had carried one of the shell handles as an EDC knife back when they were popular thought of them as users. Were they any good, or were they useless as working knives and just for kids? Thanks.
