It sounds as though you only collect them anyways instead of using. So if that's the case, it doesn't hurt to have a variety of all the blade shapes. If you were using them, I can understand sticking to one or two blade shapes that work for you.
I use all my knives, so my suggestion is use them as they were meant to be and you might be surprised at how much you like a particular blade shape you never considered in the past. I have found uses for almost all blade shapes, so I let that dictate what I carry on a daily basis.
no, i do have a box of users, in fact, when Glenns done modding that 15 i sent him, that will be a user. that 15 clip came used, and has a patina. Cant wait to put that in my pocket. also i managed to get a 2014 BF knife from a user, well paid for it, its not here physically, yet. that one was a user so it will be likely in the user box as well, unless i really polish off the patina and store it. but then the BF member said he doesnt have the tube/paper. So im still on the hunt for one that is mint for my collection. Actually was gonna consider buying someones nit 77 clip and having the blade swapped but then the 2014 blade is unique and stag is so touchy... also love stag, the ben hogan came in boy is that pretty. pinched bolsters, wish they were regular but ill live with it.
in my ideal world, id have two of every knife id really want. one to store and one to use. i have a hard time using a new knife, its a condition ive suffered from ever since i started collecting as a kid. thats why my collection has a few repeats for certain things. another recent obsession was copperlocks, i almost bought yours actually, in the autumn bone? i have the blues in variation, the mini and the full copperlock. but cant bring myself to put it in my pocket. want to buy a used one just so i can carry it.
All ive sorted my gecs from new/used. a few i bought from BF members claim to be new so i keep it with the news. they really just get fondled and put back in the wax paper and back in the tube. boy if i can find a used big clip 48 for a decent price id be happy to put that in my scrubs pocket. (ahem 2dead cough cough sell me one

, any one seen him about? hes been mia)
the only knife i never had an issue with using was my opinel. i bought two 9s when i was like 16. one stayed oiled, and the other is a round the house user.
i just find the clip blade so versatile, that it is my favorite blade shape. im sure itll lack in some areas, but overall i have quite the obsession with clip blades. Ordered the colt branded 17 inch bowie clip just for fun too, it brings a smile to my face every time i take it out. i think i dragged up a dead thread about clip blades the other week cause im still learning on what they are called. also made a comment here asking if someones got all of GECs clip blades so I can see them in comparison. The users in my cigar sort box includes 5 clips, the sak pocket pal, and a very old remington that has a clip and sheepsfoot. they are out of the picture because that thread was about single bladed slips. I do intend to get other gecs with clip blade in the future.
