I love vaquero style blades and find them very usefull as they cut and pierce like crazy.One of my favorite knives is old style linerless El hombre, by Cold Steel, 4inch vaquero blade plain edge ,made in Japan in aus8.I put this knife through hell and it never let me down,and also tested it on old carpet many times for its cutting and stabbing efficiency.It performed extremely well.Knife is also very light to carry and I consider it one of best SD folders that Ive handled.Any experiences with these types of blades,all opinions are welcome.
