In the case of GEC they call it a Bullnose.
Thought I had missed the initial offering on these but found a site in WV that had them. Very nice fit and finish. Excellent snap with half stop. The pull isn't too hard so that you break a nail but it's not one that is easy to pinch open. Took a few licks on my Sharpmaker to get the edge shaving sharp but it's good to go now and in my pocket for the next week or so at least.
The sodbuster pattern is one I've liked for a long time. In addition to this one I also have a large Boker Tree brand Gaucho, Queen Country Cousin and a large Case Sodbuster. Great pattern and a handy EDC.
