Thanks, Robert. Maybe this Pathfinder I got is an anomaly with the inner and outer liners all at 0.025? Is your two layers one like this one, no back tools, or is a GAK or Trooper (awl and corkscrew on the back)?
If you're interested in different sizes of 108's, you might look up my posting on March 4 of this year where I noted a difference in the width of either the saw (utility tool) or the covering saw guard on various models like the Hunter, Trooper, & Pathfinder.
