I like the looks of long pulls,as well. But in some cases,mechanically,they are a disadvantage.
On a clip blade,if the knife has a very firm pull,if that same knife has a long pull rear of the tip area,rear of the swedged clip,it makes it very hard opening,as compared to a crescent nick under the swedge,out by the tip,for leverage.
If you look at old knives,some Case & Schrade,I think you'll see it was done this way.
Also,a recent knife I had built by Dan Burke,a swayback with a long pull on the master sheepfoot blade.In this case,Dan does it both ways.He can also put a crescent nick out near the end of the blade. On this knife,it is a natural action to grab hold of the blade out near that high end & pinch it open.That in itself just about makes the long pull version of this blade just for show.If it had the crescent style,while not as good looking to many,it is way more useful.
IMO,there are mechanical situations that benefit the use of one style,to the other,putting "looks" aside. If you look at old traditional knives ,in different time periods,they just about tried it all
