No physical impediment or disability at all, I guess I've just been spoiled with my sog aegis which is really good in this specific measurement. When my aegis is in my pocket I can reach in and get my entire hand around it, I get about 90% of my fighting grip. I can put my thumb on the stud exactly the same way I would if I had just picked it up off the table to deploy it. I can feel almost the entire knife and get a great purchase on it. All I have to do to complete my fighting grip is wrap my fingers entirely around the handle, which is the max amount of grip available due to the very nature of the folding design, you can't get your whole grip until the blade comes out, unless you get an otf, which even then can experience different limitations of the same nature. When drawing the knife, due to sogs excellent clip design and placement, I get that excellent grip and I feel no "fabric pressure," meaning I dont feel my pocket pulling on the fingers while it is being pulled out of the clip during deployment. This pressure to me is very annoying because it can compromise that grip that I like so much by literally forcing your fingers off the handle. This is why I sold the spyderco stretch. I didn't feel the handle was long enough past the clip and I felt enormous pocket pressure during deployment. I also could not get the right grip and access to the deployment hole in the pocket. I mainly use my folders for tactical purpose, meaning I have my multitool in my back pocket if I need to cut a wire or whatnot. I want my folder to come out fast, which is why I'm seriously looking at doing my own custom waving, but being able to feel the stud/hole and maybe even deploy the knife before it fully leaves my pocket is a big attraction to me. Any knife that makes a gross demonstration of that, like in my opinion the spydie stretch, is gone pretty quickly. Does that answer your question at all?
