I have not done any significant cutting tests yet with my Temperance 2, but I will say that the most significant difference with the original Temp is in the handle, as yab's fine photos show. From a SD standpoint, the knife works amazingly well in many different grips. As I am in the "pikal" and FGEU schools of defensive bladework, I was glad to find that the knife feels great in these modes. The slimmer handle of the new Temp facilitates discreet carry, and the "G" clip on the sheath reduces the sheathed knife's profile as well. I am ambivalent about thumb-capping in "pikal" or "ice-pick" mode, so the loss of the groove on the original's butt is inconsequential.
I had heard that one application of the original Temp as conceived by Mr. Glesser was for his personal defense when hiking in cougar country. I would appreciate verification of this; and if possible, an explanation of the technique. As an amateur student of cougar behavior, I'm curious. These animals generally attack from ambush, with little prior warning, and they tend to pounce on the backs of their prey with a bite on the head or neck. How would a hiker carry and utilize the Temp to defend against such an (unlikely but frightening) occurence?
