I found this Robeson Serpentine (or Dogleg) Jack in a local hunt recently and finally got some photos. This was one of those opportunities that came along - not in my collection focus but always thought Robeson is a classic older cutlery... and Charlie sure likes them

... Accordingly I wasn't going to leave this one behind based on the following - I'm fond of jacks, serpentine patterns, condition was good and the price was very right

- blades though sharpened appear full length (at least the master and believe pen blade is near full as well), good snap on both blades, brass liners and one solid knife (3 & 5/16" closed)... Anyway - from the tang stamp "Robeson (arched)/U.S.A./Cutlery" it appears to have been made between 1917-1939. Only master blade was stamped and back side of master tang had a stamp with the model # "623480". There is not a tang stamp on pen blade. No shield (actually don't think it ever had one based on front scale) and jigged black composition handles in great shape. Interesting jack design to me in that the nail nicks for master and pen blades were on opposite sides of knife with pen blade on pile side... BTW - this knife bit me today playing with it

- razor sharp blades for sure
I would very much appreciate any other info on this knife... or observations from the "seasoned" Robeson collectors about it (for example did some not have shields??, was this a common pattern?, etc etc)... don't know much about Robeson other than it was a quality old company!! Thanks fellas!!!
(As an aside - now my collection is starting to evolve for good reason into having a smaller special category called "Special Opportunties" - a few other knives in this category, just as examples, are my Camillus 72 with Rogers Bone (short line stamp), Walden Knife Co Hawkbill Pruner, Case 6280 and Schrade Walden Sheepsfoot, original Schatt & Morgan Tidioute PA Stockman and a few others - heck this part of my collection is getting larger than I thought

- funny how collections evolve - still have the same focus for the great majority of my knives but added a few that no doubt were speaking to me
