I look forward to seeing your choice KJ, and everyone else's. I must pick a traditional 2 blade jack knife, my favourite pattern. I could happily live with a 15 Barlow forever, likely a 2012 spear or the 2014 red soup. I have a many 56s and would want for nothing. The 92 is a superb knife to use and carry. A 73 it goes without saying would absolutely work, my 734208 in burnt stag would be wonderful. I just noticed it is turning color a bit due to verdigris, might move into a pocket. Nice 5 pulls and outstanding (even for GEC) fit and finish. 78 would work, so would the 48. The 2 blade Diamond Jack of 13 in blood red would make for a happy pocket for life. A 38 farmers jack would be excellent, I long for one in stag with rattail bolsters.
Should anyone have read this rambling post featuring numbers, and understood, you must also be afflicted with GECitis and noticed 2models pointedly missed. My runner up is the 85. Specifically 852211 Real Harness Jack in Antique Walnut Jig Bone. The handles, fit, finish, beauty, elegance and pocketable type are perfect. But my lifetime knife would have to be another CC sfo, the 772214EC Washington Jack. Ideal in any of the 5 handles, I am conflicted between blood red and smooth polished stag. Having them in hand does not make the choice easier. The red is the best red I have ever seen on a knife. The polished stag has colour and figure from stamped endcap to grooved bolster. Out of dozens I am down to 2, if I could have but one I was decided stag but the red is so good. Red 77 Washington Jack for me. Class of its own. A sheepsfoot version I patiently wait for.
