Had a Benchmade 550 440C, then a 551 440C and a 556 440C. Was going to switch to the 154CM versions, but opted for a large and small Ritter numbered instead. Traded or sold the small Ritter off down the road, and just bought another one. Still have the large, got a 556 154CM for my little bro but sold that to get him something else. He could use a 440C 556, with his 40TR.
Also got a 710 154CM, got Sebbies and Striders, figured I didn't want the 710 anymore, I was wrong, got a 710 D2. Same thing with a 707, got the 707 before the 154CM 710, picked up a 705, and got rid of all of them with the 710 and 707.
Got a combo edge black blade Rukus, I hate serrations, picked up a [E Rukus recently in a trade.
Got a small micarta Sebenza, traded it for a used SMF, now I just ordered another one.
Got a 1095 Rat 3 at a local knife show, traded for a D2 RAT 3, traded or sold that one, just traded into a RAT RAT 3.
Had an Endura 3, traded it, then got an Endura 4, traded it, then got an Endura 3 again, traded it, and now I am the proud owner of an Endura 4.
Got a Spyderco Military 440V, then a CE black S30V Millie, those left, now I have a PE Millie.
Stuff I plan on getting
Strider PT, had a regular PT, traded or sold that, got a recurve PT in a trade, traded or sold that, now I am either going to get a regular PT or a PT CC.
Had a Pacific Salt SE, looking for a PE.
Last but not least, had a 707, got the 707 before the 154CM 710, picked up a 705, and got rid of all of them with the 710 and 707. Now, looking for a 707 again, and, probably a 705.
