New to the forum, a Kershaw Leek got me started. I have a ZT0561, Sog Tomcat,Vulcan, Dirk Tighe a Blur and several others. I am looking for an unassisted ultra smooth opening knife. Must have a thumb stud but a flipper option would be nice. Prefer to stay away from liner or frame lock. Something like the axis lock or what Sog uses but that is not a deal breaker. Won't really be a user. I have VG10, SV30, 154CM and Elmax, another steel would be nice. Titanium would be a plus. Midsize to larger. So far the ZT 801 looks good but no thumb stud. Different price ranges are ok for the right knife. Prefer to keep it around $200 or so but can do more for the right knife. Are trits ever added to knives? That would be sweet. Thanks in advance for any suggestions.
