I've been switching out between a Gerber Applegate-Fairbairn Combat Folder, and a Kershaw Blackout. But they're just not working out for me. I'm really want to get a folder that will allow me to carry tip-up. I'm a little short on money so I need something affordable. I've found a couple of decent buys online. First is a Spyderco Tenacious (http://www.cutleryshoppe.com/spydercotenacious-plaincomboorserratededge.aspx). Second is a 5.11 Ten-Eight Tanto (http://www.lapolicegear.com/511-tactical-flat-foot-tanto-knife.html). So...what I really need to know is what is the significant difference between the spear point and the tanto??? Also, some ideas on good knives for about $50 would be nice. Thanks!
